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.
