Paper gaskets failing on compressor

[rcx132]

I used gasket paper when I rebuilt my compressor but all the gaskets I made started failing one by one. I used good quality gasket paper but they go brittle and burnt.

The first gasket that failed I made a new one from copper, but the head gaskets are bit big to make from copper. Ideas for what to use that will stand up to the heat?

Also noticed that a fair bit of fine blast media is getting through the sponge filters as I do some outdoor blasting. Are car type paper gaskets better? Anyone know a car with a simple airbox that's easily plumbed into some 1.5" pipe so I can do a cold air feed for my compressors? Idea is to take a feed from further away from the area I do my blasting, use some better air filter, e.g. an car airbox.

Other simpler idea is to use sponge filters soaked in oil like you get on motorcross bikes, would be easier to connect than plumbing in an air box.

As always, thanks for the help!

There is fancy types of graphite impregnated gasket paper for high heat available on eBay, there's a few different grades. Search for high temperature gasket paoee.

Used on my compressor last year and all good.

I bought a cheap air filter from halfords for my compressor...just fits on with a jubilee clip.
It's had lots of water falling on it from a dodgy roof but is still going ok.

Having also found that sometimes paper gaskets don't last (or I was feeling lazy or pushed for time) I put the works compressor together with anaerobic flange
sealant, like Loctite 574 or better still the high temp version, 510.

It's lasting very nicely, was very quick and easy to do and a little bonus in my view was by eliminating the thickness of the gasket it's raised the compression ratio and is now a better compressor.

Might be something to consider.

Permatex ultra copper spray. Designed for high-temp gasket sealing, goes on super thin.

A single cylinder bike airbox would do it. Get a foam filter for it and oil it then nothing will get through.

I reckon a thin sheet of annealed ali would be a better job than paper, mine went a while back and it cost me £60 for a complete set because they would not supply just the head gasket.

Thanks, some top ideas here!

Copper ie hot water tank is what I use for the pump compressors that are running 24/7 on near full pressure, ie they dont get to a pressure and stop compressing it is a total loss system, you can anneal and reuse also making the bridge piece wider helps but only widen them into the inlet side the cool intake air tends to keep the bridge piece cooler.

For a simple air filter I was wondering about one of these, I think it's the air intake filter for the air brakes compressor on a truck.

Seems like a low cost simple solution. The car air filters have minimum 50mm necks so would need adaptors, crankcase filters are either low quality or low filtration, using a motorbike airbox seems ok, but means buying hose and fittings to plumb it all up. This filter would just connect using a single fitting.

Some forums said a truck compressor is 15 CFM so the filter through-put should be ok. That was the CFM for an American truck, maybe our baby trucks have lower CFM, don't know.

I am sure that using spin on oil filters as compressor air filters has been discussed on here in the past but I have no personal experience of using them.

I've done it that way without any issues

Just need a barrel nipple that will screw into the filter usually 3/8 bsp or maybe on bigger filters 1/2, threads might not match exact but because they are taper and for a air filter its good enough.
They work as a silencer too and are usually 15 micron ideal for small stuff even paint

Now that's an idea. I have a couple of new old oil filters that I've long since parted with the vehicle they fitted. Ching, ching, money saved.

@rtbcomp has used one for that purpose, I believe.

I have a stihlsaw filter on one mine. they don't get better than that for keeping large amounts of dust out

He has indeed. Rover 100/Metro type. I use 2 on my Clarke with a T-Piece, on the end of a length of vacuum cleaner hose. This is to take the intake away from the hot motor and put it inside a box to cut the noise down. As said screwing it on to a BSP thread locks the threads nice and tight.

You get the idea - I've actually pinched one of the filters for another compressor as I don't use the Clarke at the moment
