Making a seal between two elastomer faces
Making a seal between two elastomer faces
(OP)
Hey guys,
I need to make a seal between two elastomer surfaces (specifically polyurethane). At first I simply thought to use an o-ring but my manufacturer told me the seal will fail sooner rather than later because I'm not making a seal between two "rigid" faces.
How else can I make this seal? It only needs to hold 100psi MAX.

I had no idea a steel o-ring was an actual thing. Thanks for mentioning that.
On that note however, they aren't on mcMaster. Could I just use a thin washer? Do you know what a proper steel oring is called and where to find it?

How are you clamping the parts together? If you are using screws on solid PU parts you will likely not have any clamping pressure between the screw locations unless you have a metal clamp ring.

The design looks great, now I just have a seal problem elsewhere :)
