38898 Central Pneumatic Compressor leaking gasket?
My compressor was leaking air.
Took off the cover that says DO NOT REMOVE. NO OWNER SERVICABLE PARTS. It is the switch compartment. Found a gasket had a hole in it. It was easy to get at and the gasket should be replaceable.
Where could I find a replacement gasket ?? I would hate to throw the compressor out just because of a leaky gasket. That is all it needs to get it back working again. HELP !!!!
Larry, just had a couple of questions similar, so I wrote a blog entry that addresses that issue.
Have a look at the latest entry here: http://wrw51.wordpress.com/
The full posting is in the December 2011 directory, and portions of it are copied here:\"Recognize first of all that a compressor pump head gets very, very hot in operation. Yes, you can burn skin with the heat generated, so any gasket material has to be heat resistant.
What some visitors to my about-air-compressors.com info website have done is as follows.
They acquired gasketing material. They disassembled the pump and located all the gaskets that were present. They then either removed them to use as a template to make new ones, or used the surface where the original gaskets were installed as a template, if the gasket was beyond removal in one piece. With the old gasket template as a guide, they marked the new gasket material appropriately, and cut the material to suit.
If your air compressor won’t build pressure past a certain point, the most frequent causes seem to be either the intake or high pressure reed / flapper valve is failing, or a gasket is letting go. You may, nor may not, be able to see the failure point if it is the gasket. Yet, once you have the pump apart, you might as well eliminate that as the potential problem, by installing new gaskets.
If you can’t buy them, you can make your own.
I have not dealt with the company myself, but a source that has popped up for gasket material is:
I don’t think you can buy from them, but you can find the material and a source through them, evidently."
Central Pneumatic air compressor check valve blew?

Were you able to help Nathan in Houston?
I also have a Central Pneumatic 2HP 8 Gal compressor (40400) about 2 or 3 years old. I use it only about once a month for a few minutes at most.
I think I blew the "check valve". Part of it that actually looks like the head of a bolt broke and "blew" off. I called the 1-800 and they said that the part was not available. The valve screws into the tank and connects the release with the air control mechanism as well as the air pressure. I bought the air compressor at Harbor Freight. Can you help me?
My guess is it is a pressure release safety valve that blows if the pressure is too high. I don't think pressure was the cause of the "blow". I think it was more that the part was a bit weak.
Anybody have an idea on getting a replacement?
Bob, you say "Were you able to help Nathan in Houston?" Hmmm. What's Nathan's compressor issue. There are thousands of posts on this site, and despite my prodigious memory /:-) I don't remember.
I have never heard of a check valve blowing apart, so this stymies me.
Find out where HF sends air compressors for repair under warranty, and talk to those folks about a replacement.
The check valve isn't rocket science, and as long as you can thread a new one into the tank, and connect the line from the pump and the line over to the switch, any check valve that functions will work.
"My guess is it is a pressure release safety valve that blows if the pressure is too high." Yup, and certainly not the check valve. See the PRV valve page for info on it and the CHECK VALVE page for info on them.
