Rubber Sealing Capabilities
Rubber Sealing Capabilities
(OP)
Hi,
I was wondering if there was a way to determine the minimum required "sealing stress" between a lapped stainless steel surface and an elastomer (we use a number of different elastomers the most common being Viton). Is there anyway to accurately predict the sealing characteristics of a particular material? Are there any common tests that are performed to determine these properties, and if so where can I obtain the data?
I would appreciate any suggestions,
thanks,
Andrew

RE: Rubber Sealing Capabilities
(4/3) E [(2xd)^0.5 PI D/d-x]
Where:
E = Young's Modulus of elastomer
x = deflection
d = diameter of cross section
D = mean diameter of seal
Remember that 'x' in the above equation does NOT mean multiply !!
Hope this helps.
Conrad.
