help with compressor!

We do that with our molds, just cut and it is compressed when mounted in the machine. Wrks well in a relativel low pressure application of about 3 bar pressure.

There is also a special (expensive) adhesive for O rings so you can make your own. I don't know if super glue would work.

Ted, cut the ends as flush as you can and use some super glue. I am sure there is some special super glue for this .. perhaps Locktite 404 ... but I have had success with just plain old super glue. There are O-ring kits that come like that. Just a long length of rubber, a cutting jig, and some super glue.

Actually, I don't think super glue will work with the type of rubber. Just cutting face flush should work fine after compression. DON"T cut them exact fit, cut just a micron longer for shrinkage. When compressing the rubber tends to pull apart at the joint. YOu could try a dab of Permatex RTV silicone at the joint. The high temp red that I have says "pressure resistant"

Hello all, I have an air compressor that blew out the two different O-ring gaskets on the top of the head. One is shaped like a D or half moon, and the other is round. Problem is, I just received the replacement O-ring material, and it is about a two feet long red rubber cord. I was expecting them to be pre-fit. It is the same material as what was originally used. How do I join it together to make sure that no air blows out of where the O-ring meets up? Am I to assume that when the O-ring material is cut to the proper length and face off against each other, that the torque of screwing the metal parts together will compress the O-ring together to form an airtight barrier? Below is a link to a page on my site that shows pics of the top of the motor with the old blown 0-rings in place.;

as one poster stated, cut ends on a 45, and as another suggested, either red rtv or copper rtv, and remember, a small dab 'l do ya
