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.;

Thanks for the help.

It works very well. We've glued-up O-rings for years with CA.

Cut ends at 45 degree angles and lay one on top of the other.

404 is the stuff. Expensive and short shelf life, but works
remarkably well.

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

Super glue works fine on neoprene. Can't say about other o ring materials.

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.

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"

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.

cyanoacrylate ester will not work on siliconized rubber gasket material it
will dry up and crack off

CA is the adhesive of choice for make-your-own o-rings.
