Spring lip seals have been used for many years. Spring lip seals are used in a manner similar to conventional elastomer seals, such as o-rings. Elastomer seals often fail due to conditions that often occur in their operating environment, such as chemical corrosion, extreme high or low temperatures, extrusion, friction, or compression set. However, spring lip seals have different structures and do ...

OD (Outer Diameter) face seals are used on the FLS and FLS-R seat. They are a type of mechanical face seal that's used in conjunction with the ID (Inner Diameter) face seal to provide a seal between the seat and the seat pocket of FLS style valves. FLS ID and OD face seals are used in all sizes of valves ranging from 1-13/16” to 7-1/16”. The OD seal you’ll receive is spring-loaded and pressure-ene...

Spring energized face seals are often used in static sealing applications. PTFE face seals offer advantages over traditional O-rings in terms of pressure handling, chemical compatibility, and operating temperature range. Often used in cryogenic applications. Face seals are designed for either internal or external pressure, but not both. Product Type Product Description Technical Data Working temp ...
