This introduction focuses on FOREVER SEALS PTFE spring-energized seals specially designed for high-precision dispensing machines.
Conventional rubber O-rings easily suffer from swelling, wear, leakage and unstable dispensing accuracy when working with UV glue, epoxy resin and various chemical solvents.
Our spring energized seals feature low friction, excellent chemical resistance, automatic wear compensation and long service life, perfectly solving dripping, leakage and frequent replacement problems of dispensing valves.

FOREVER SEALS FS series FFKM O-rings directly replace DuPont Kalrez in semiconductor manufacturing, with equivalent performance, 25%-30% lower procurement costs and 70% shorter delivery cycles, ensuring stable production.
