Campbell Hausfeld has been making air compressors for home garages for a very long time, which means there are a lot of older machines out there still running and a lot of owners hunting for campbell air compressor parts to keep them going. The good news for a first-time repairer is that most compressor fixes come down to a small handful of parts: the pressure switch that turns the motor on and off, the intake filter that keeps dust out, the little seals that stop air from leaking at the tubes, and the accessories that let you actually use the air. This guide walks through six of those items and explains, in plain words, what each one does.
One honest note before we start: only three of these six are made by Campbell Hausfeld itself (the two accessory kits and the CW209300AV switch), while the other three are compatible replacement parts from other makers sold “for” Campbell Hausfeld machines, and the models differ mainly in which job they do, from switching power to sealing tubes to inflating tires.

CW219300AV Pressure Switch For Campbell Hausfeld
Best for: Owners replacing a 120/155 PSI switch
Pros
- Cuts in 120 psi, out 155 psi
- 26 amp rating, 120 or 240 volt
- Four-port switch with unloader fitting
Cons
- Made by WHFZN, not Campbell Hausfeld
- Check model fit before ordering
A pressure switch is the small box that watches the air pressure in your tank. When pressure drops to a set point, it turns the motor on (this is called “cut-in”); when the tank is full, it turns the motor off (“cut-out”). The CW219300AV Pressure Switch For Campbell Hausfeld is a replacement for that part, made by a company called WHFZN rather than by Campbell Hausfeld. The listing says it cuts in at 120 psi and cuts out at 155 psi, carries a 26 amp current rating, and works in 120 and 240 volt applications. It is a four-port, two-pole switch with a 1/4 inch FNPT inlet and a 1/4 inch quick disconnect fitting for the check valve line, and the body is listed as aluminum.
The description includes a useful beginner tip: if your compressor keeps restarting, or the unloader valve on the switch keeps hissing air out, the check valve may be the real problem rather than the switch. That is worth reading before you buy anything. The seller also invites buyers to send their model and serial number if they are unsure about fit, which is a sensible step, because pressure switches are not one-size-fits-all.
This suits an owner whose existing switch carries the CW219300AV part number and who is comfortable with a compatible part. If you would rather stick with a genuine Campbell Hausfeld switch, the CW209300AV further down is the authentic option, though it is a different part number for different machines.
Air Compressor Silencer HL018200AV AirFilter Fits for Quieter Intake

Price and specifications are read from the Amazon product page and can change.
Air Compressor Silencer HL018200AV AirFilter Fits
Best for: Quieter intake and cleaner air
Pros
- Replaces HL018200AV filter silencer
- Metal 20mm thread
- Blocks dust and moisture
Cons
- Third-party SANFAY part
- Filter media not described
Every compressor sucks in outside air, and the intake filter sits where that air enters the pump. The Air Compressor Silencer HL018200AV AirFilter Fits is a SANFAY-made replacement for Campbell Hausfeld part number HL018200AV, so treat it as a compatible part, not an original one. The listing says it fits Campbell Hausfeld along with several other compressor brands, has a metal 20mm thread (listed as 1/2 inch PT), and measures about 3 by 2.4 inches, with a thread diameter of about 0.8 inch.
According to the listing, the filter blocks dust and moisture, reduces noise and helps the compressor run efficiently. That matches how intake filters work in general: a clogged or missing filter lets grit into the pump and makes the intake louder. The listing does not specify what the filter material inside is made of or how often it should be changed.
This is a good pick for someone whose compressor has become noisy at the intake, or whose old filter is cracked or missing. It is a small, simple swap that beginners can usually do by unscrewing the old one, but measure your thread first. It does nothing for electrical or leak problems, which the switches and tube seals handle.
Campbell Hausfeld 20-Piece Air Compressor Accessory for a Complete Starter Setup
Campbell Hausfeld
Campbell Hausfeld 20-Piece Air Compressor Accessory Kit, MP604103AV
Price and specifications are read from the Amazon product page and can change.
Campbell Hausfeld 20-Piece Air Compressor Accessory
Best for: New owners wanting a hose included
Pros
- 25 ft nylon recoil hose
- Blowgun, tire chuck and gauge
- Industrial quick-connect fittings
Cons
- Full piece list not itemized
- Heavier than the 17-piece kit
Not every “part” is a repair. Many new owners discover their compressor arrived with no hose or tools at all. The Campbell Hausfeld 20-Piece Air Compressor Accessory kit, model MP604103AV, is a genuine Campbell Hausfeld product that fills that gap. The listing highlights a 25-foot nylon recoil hose (the coiled, springy type that pulls back on itself), a blowgun, a tire chuck, a gauge, inflator needles and industrial quick-connect fittings.
The recoil hose is described as preventing kinks and tangles, and the kit is designed to be corrosion resistant. Listed uses are blow cleaning and tire inflation, and the kit weighs 1.7 pounds. The listing does not itemize all twenty pieces, so if you need one specific fitting, check the photos or packaging carefully.
This kit suits a gift-giver shopping for someone who just got their first compressor, since it covers both the hose and the everyday tools in one box. If the person already owns a hose, the smaller 17-piece kit below may be the tidier choice.
Campbell Hausfeld 17-Piece Air Compressor Accessory for Owners Who Already Have a Hose
Campbell Hausfeld
Campbell Hausfeld 17-Piece Air Compressor Accessory Kit (MP284701AV)
Price and specifications are read from the Amazon product page and can change.
Campbell Hausfeld 17-Piece Air Compressor Accessory
Best for: Starter kit for existing hose owners
Pros
- Brass parts resist corrosion
- Couplers rated 25,000 cycles
- Dual-foot chuck and blowgun
Cons
- No hose in the listing
- Some listing fields are placeholders
The Campbell Hausfeld 17-Piece Air Compressor Accessory kit, model MP284701AV, is another genuine Campbell Hausfeld set. The description lists a blowgun, pressure gauge, dual-foot air chuck, coupler, plugs, couplings and inflation nozzles. A dual-foot chuck has two angled heads, which makes it easier to reach awkward tire valves on vehicles with dual wheels.
Two build details stand out. The brass components are described as corrosion resistant and help prevent sparks, and the plugs are cold-forged for strength. The listing also says the industrial couplers are designed to withstand a minimum of 25,000 life cycles without leakage, which is a useful promise for anyone who swaps tools often. The listing does not mention a hose, and some fields (such as color and shape) are filled with placeholder text, so rely on the description for what is inside.
This fits someone who already has a hose and wants the fittings and inflation tools that make a compressor useful day to day. Anyone who needs a hose as well should look back at the 20-piece kit.
Campbell-Hausfeld CW209300AV Pressure Switch for Air for a Genuine Replacement
Best for: Genuine replacement on listed models
Pros
- Authentic Campbell Hausfeld part
- Replaces obsolete CW209300AJ
- Long compatible model list
Cons
- Cut-in and cut-out not listed
- Listing says no warranty
If you want an original part, the Campbell-Hausfeld CW209300AV Pressure Switch for Air compressors is an authentic Campbell Hausfeld replacement. The listing says it replaces the obsolete part number CW209300AJ, fits many Campbell Hausfeld compressor models, and is a standard duty part built for longer life. The description lists a long run of compatible models, including VT633500, VT632900, EX840100, VT619504 and many more, so compare your compressor’s model plate against that list.
What the listing does not specify is the cut-in and cut-out pressure or the amp rating, so you cannot compare it number for number with the CW219300AV above. The listing also states “No Warranty”, and its “Included Components” field says “Pump”, which looks like a listing error for a switch this size (2 x 1 x 1 inches, 4 ounces), so do not expect a pump in the box.
Choose this if your compressor model appears on the compatibility list and you prefer a genuine Campbell Hausfeld part. If your machine uses the CW219300AV number instead, the WHFZN switch is the one that matches.
ST085200AV Molded Ferrule Tube Seal for Stopping Small Leaks
Best for: Fixing leaks at tube fittings
Pros
- Two 1/2 inch seals per pack
- Silicone ferrule design
- Long model fit list
Cons
- Third-party XXHCML part
- Small part, easy to misplace
A hissing leak where a metal tube meets the pump or tank is one of the most common problems on older portable compressors. The ST085200AV Molded Ferrule Tube Seal addresses exactly that. It is made by XXHCML, not Campbell Hausfeld, and is sold as compatible with Campbell Hausfeld portable compressors in the WL, VS and VT series, with a long list of model numbers in the listing.
The listing explains how it works: the seal sits inside a compression nut on a copper or aluminum tube, and the nut then attaches to a compressor component, squeezing the seal to stop air leaks. You get two red silicone seals in the 1/2 inch size.
This suits the hands-on owner chasing a leak at a tube joint. It is the smallest part here, but often the fix that brings a tired compressor back to holding pressure. If your leak is at the switch or tank drain instead, this part will not help.
How to Choose the Right Campbell Hausfeld Air Compressor Parts
Start with the symptom. If the motor will not start, will not stop, or keeps cycling, the pressure switch is the usual suspect, but read the check valve tip in the CW219300AV listing first. If the compressor is loud at the intake or the old filter is damaged, the HL018200AV-compatible filter silencer is the simple swap. If you hear a steady hiss at a tube joint, the ST085200AV tube seals are the likely fix.
Next, match the part number. Campbell Hausfeld labels its parts with codes such as CW209300AV or ST085200AV. Find the number on your old part or in your owner’s manual, then match it exactly. For pressure switches this matters most, because the wrong cut-in and cut-out settings can leave your tank under-filled or over-pressurized.
Then decide between genuine and compatible. The CW209300AV switch and both accessory kits are made by Campbell Hausfeld. The CW219300AV switch, the filter silencer and the tube seals are third-party parts made to fit. Compatible parts can work well, but you have less assurance from the original maker, so double-check fit with your model number.
Finally, if nothing is broken and you just want to use your compressor more, pick an accessory kit: the 20-piece if you need a hose, the 17-piece if you already have one. If you are still deciding on the compressor itself, our air compressor comparison guide explains the basics of tank size and pressure.
FAQ
Which Campbell Hausfeld part should I buy first if my compressor will not build pressure
Listen before you buy. A steady hiss at a tube joint points to a tube seal, while a motor that never switches on points to the pressure switch or wiring. The CW219300AV switch listing also notes that constant restarting or air escaping at the unloader valve often means a faulty check valve, which none of these six parts replaces.
Are all of these parts made by Campbell Hausfeld
No. The CW209300AV pressure switch and the 20-piece and 17-piece accessory kits are Campbell Hausfeld products. The CW219300AV pressure switch (WHFZN), the HL018200AV filter silencer (SANFAY) and the ST085200AV tube seals (XXHCML) are compatible parts from other makers.
Is the CW209300AV the same as the CW219300AV pressure switch
No, they are different part numbers. The CW219300AV listing gives cut-in at 120 psi and cut-out at 155 psi. The CW209300AV listing does not specify its pressure settings but does list the compressor models it fits and says it replaces the older CW209300AJ.
What is the difference between the 17-piece and 20-piece kits
The 20-piece kit includes a 25-foot recoil hose, while the 17-piece listing does not mention a hose. The 17-piece kit is described with brass, corrosion-resistant parts and couplers rated for at least 25,000 cycles. If you also carry a portable inflator, our look at a portable air compressor for the car covers a different kind of tire tool.
How do I know if a tube seal will fit my compressor
Check your model number against the long list in the ST085200AV listing, which covers many Campbell Hausfeld portable models in the WL, VS and VT series. The seals are 1/2 inch, so they need to match a 1/2 inch tube and compression nut.
Can a beginner do these repairs
Filter and accessory swaps are easy for most beginners. Tube seals need a wrench and some patience. Pressure switches involve electrical wiring, so always unplug the compressor and drain the tank first, and ask a qualified person for help if you are not comfortable working with wiring.
