A premium all liquid cast polyurethane loaded lip seal

Characteristics

The Yellow Jacket is a premium all liquid cast polyurethane loaded lip seal. The energizing element is cast in place and chemically bounded to the inside of the cup resulting in a one piece double durometer seal. This unique design provide 95% more energizer volume than that provided by an ‘O’-ring insert, and the filler cannot pop out or extrude in service.

Liquid cast polyurethane materials with their immensely variable processing possibilities, have a available the physical properties most desired for sealing applications. For example, the energizer has virtually zero compression set ( < 1% as measured to ASTM D-395, method B, for 22 hours at 70°C), excellent resilience (Bashore Rebound; 46%), and good flexibility right down to minus 40°C. The Yellow Jacket is ideal where optimum sealing is required down to very low pressures and low temperatures. Its high resilience also allows it to accommodate large amounts of side play.
