Dual Seal Flange Static Seals , Heavy Load Cover Seals
The SSA type is a static seal made of high-modulus polyurethane with a low compression set. The symmetrical ß-profile keeps it from twisting while it's being put together and stops it from extruding under pressure. It can withstand high pressure and wear. Could be an alternative solution to replace o-rings and anti-extrusion rings in high pressure.
