Description

The SSA type static seal has been developed and tested for many years for static and sometimes dynamic sealing applications. It is mainly used as replacement of o-ring and antiextrusion ring. The use of a high modulus polyurethane with a low compression-set prevents winding during assembling and avoid extrusion in working conditions. One single piece with symmetric profile allows the operator easier installation reducing at the same time the stock handling. The proposed material is a “C0” type polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance. Compound reference: C0 It is important to remove flashes or cutting edges to avoid damages. It’s also recommended to make a lead-in chamfer for easier assembling.
