Air Compressor Parts – Finding Replacements & Substitute Parts

Depending on the type of air compressor you have, getting compressor parts can be straightforward, or nearly impossible. Why?

If your air compressor was acquired from an industrial-type compressor distributor, not only will that distributor be able to get parts for your air compressor, but they likely also provide a service department that will visit your shop, diagnose the problem, obtain the compressor parts, and then install them for you.

However, many of us have an air compressor that we purchased from a big box store, department store, auto parts outlet and the like. These are all compressor distributors too, but they have nothing in common with the industrial air compressor distributor.

The retail distributors offer a range of compressors. They often have a house brand air compressor to offer too. But their business is selling consumers air compressors and air compressor accessories like tools, hose and the like. Not spare parts and definitely not air compressor service.

Rarely does any retail outlet have any compressor parts for the brand of compressor you purchased from them.

Further, is our experience that the typical floor clerk in the typical big box store have virtually no experience with air compressors, with sizing them, with identifying the correct compressor for a customer’s needs, and they surely don’t stock compressor parts.

Then where do I get compressor parts?

First off, since all air compressors will ultimately fail, where you get parts for any particular brand of compressor should be an issue for you when you are selecting a brand of compressor. Ask the vendor where you get spare parts when – not if – you need them. No parts supply? Maybe pick another brand of compressor?

Depending on the brand of air compressor you purchases, that supplier may have an online presence that can help you with spare parts for the compressor pump and motor.The logical first step then is to use your computer browser and search for – parts for xxxx air compressor – replacing the x’s are in the search string with your brand of compressor.

Many compressor parts are interchangeable

While there are many air compressor manufacturers in the world, it seems that a few of them dominate the house-brand air compressor market. What does this mean?

Just because you bought a blue compressor from one store, the yellow air compressor of the same size and appearance from another store may be from the same plant. After all, a different color paint does not really make a different air compressor.

You can’t lug your compressor with you into a store, but you can take digital pictures of parts of your compressor, particularly the pump. Take the photos with you into the store and compare the appearance of the pump on another compressor with your own.If the pumps are the same, it’s a pretty good bet that the spare parts are too. Of course, this new store may not have parts either.

The only OEM spare parts that are essential for you to use are those parts in the pump. Other items on the air compressor that can be replaced by non-OEM spares are:

  • pressure switch
  • pressure line from pump to tank
  • line from tank to unloader valve
  • tank check valve
  • tank drain
  • any gauges
  • air regulator
  • PRV’s
  • couplers

These all work the same way, and as long as a replacement fits on your compressor, you’re good to use it to replace a failed part. Just make sure if you replace the pressure switch with the non-OEM version, it has the same voltage and pressure ranges. Otherwise, if it fits, use it.

Compressor Pump Parts

As noted earlier, compressor pump parts are pump specific. A valve plate from one brand may not fit another brand.

On the other hand, it might. We believe there are only a small number of compressor manufacturers offering the DIY brand of compressors, and as such, parts from one may fit the other. Your browser search engine is your friend when it comes to finding parts from one pump that may fit another.

Find out, if you can, who it was the supplied the compressor to your store. Was it, for example, supplied by Campbell Hausfeld or Devilbiss? If you can track who supplied it to the store chain, then contact that manufacturer for help. Make sure you have the model number and the brand.

Last, but not least, many folks have manufactured their own valve plates from spring steel when they could not find an OEM replacement. Some have manufactured their own pump gaskets using high-heat automotive gasket material. If you browse for home-made compressor pump valve plates or compressor pump gaskets, you will find guidance in making your own.

What’s the compressor worth?

One thing that we have seen repeatedly is the the cost of a new compressor of the same size and make is often only a fraction more than one single spare part for that compressor.

If, in the fullness of time, you cannot find parts, then the solution is to buy another compressor with the same pump on it, start using the new, and keep the old for spare parts.

You may find that in terms of cash and aggravation, this ultimately is the lowest cost way to get your compressor parts.

Hello: I have a 26gallon 175psi Kobalt (model# VLK 1582609-99007) air compressor. I am looking for parts, in particular the seal that goes around the piston, bottom plate ring/seal and the head gasket/seal. Do you carry these parts? If so can you provide part # and prices along with phone# so I can order these parts. If not can you provide contact info in where I can them these parts. Thank You

If you Google “pump parts for a Kobalt VLK 1582609-99007” your will find sources for some parts. The piston ring can be sourced from the companies that make them, Google that, and have the dimensions of the old measured up so you can find one that fits. The head gasket seal can be made using high-heat gasket material from an auto parts store cut to suit.

Fix My Compressors is an information portal and does not sell compressors or parts. Sorry. Some of the advertisers on this site may. Good luck.

Hi Josue. Before trying to track it down on your own, did you consider asking Husky? https://www.husky.com/contact/customer-service/

My Clark pancake compressor would not start (just hummed). I found the piston stuck. Took the crankcase cover off and used WD-40 to free the piston. Reassembled and tried to start but found the crankcase cover gasket leaking. Can’t seem to get it to seal and I haven’t been able to find a replacement (part #P046927). What’s the best option to get it up and running?

If the cover gasket is leaking and their is no OEM or after market supply, you’ll have to make your own. High heat gaskets from an auto supply store could be cut to size, and I know some folks have had success with liquid gaskets.

willyr, thanks for the reply. When you mentioned liquid gaskets are you referring to RTV gasket sealant or another product? Also, if I make a gasket for this unit should it include the divider and baffles?

Mark, you’ll have to read up on the specs of the liquid gasket to ensure it is suitable for a high heat application. Since I don’t see the gasket that you are replacing, I cannot comment on what the new “gasket” will look like, but can say that it should isolate all the parts of the pump the original one did.

Since there is no replacement part or motor for the 19 gallon oil free air compressor, will a motor off of another size, such as a 20 gallon, fit and work on the 19 gallon air compressor? Is the piston rod length and the piston diameter of a 20 gallon pump the same as a 19 gallon pump?

Hi Garry. Your questions were consolidated and moved to this section.

As long as the motor can be fitted to the compressor, and has the same RPM, you can use any motor you wish on a compressor. It helps if the footprint is the same, the shaft size etc. etc, but really, as long as the pump is getting sufficient force at the right RPM, it will work just fine.

I cannot respond to the second part as I have no idea what make(s) or model(s) of compressors are being asked about. Look for parts diagrams on line for both, and check the measurements to be sure. Often pump parts can be interchanged, as so many different makes and models of compressors are made by the same company. Good luck with that.

Do they make a better exhaust height for an air compressor Central promatic 125 from Harbor Freight Louder Than Hell

The cheaper the air compressor, typically the more noisy it is Steve. Better exhaust height? Not quite sure what you mean by that. Don’t really know what a Central promatic 125 compressor is, either. Perhaps you could clarify a bit for us?

I purchased a Husky Compressor at home Depot. Someone opened the box of a new model TA2530B Husky 8 gal. oil type compressor. when i got the compressor home over two hundred miles from home depot. When I opened the box someone had taken the Air filter P/N 41.005 and the oil tank cap P/N 26.002B along with the oil that was packed in the box. This again shows again that just how sick America is. Having thieves from the white house to the very streets we all walk down. If anyone has the direct phone number of huskies manufactures please forward.

We have a really old BroomWade TS9 reciprocating compressor and we need to buy new springs for the annular ring valves. The springs are two concentric rings tied together in a single piece.

I have a somewhat cheaper air compressor that I received for christmas about three years ago. It’s only been used a handful of times (Maybe 5, no more than 12), and the capacitor already went out in it. (I troubleshooted this was the fault as the compressor comes on but the motor doesnt spin, it just hums really loud for a few and then shuts off).

In trying to find the replacement, I am having no such luck. The capacitor is a XuFENG

CBB60 120uf (+/- 5%), 250vAC 50/60hz. Does anybody know where I can find this replacement?

You can use any capacitor that fits, that connects the same way, that has the same voltage range, the same MFD or micro-farad rating. MFD might also be shown as µF. All of this information should be on the side of the existing capacitor, except the physical size. That you get by comparing the old to the new to make sure it actually fits on the motor. If you Google replacement capacitor, and input the parameters of the old one, you’ll get a match.

Hi there
I own an older Snap on 1.5 hp upright, single cyl. The check valve that threads into the tank broke. I can only find check valves that have the intake from the compressor and unloder outlet 90 degrees from each other. I need a check valve that the inlet from compressor and outlet to unloader are 180 degrees from each other.

Is there no room for a little creative plumbing, using a couple of 90 degree elbows to orient the line?
