PTFE Lip Seals
PTFE lip seals are an alternative that bridges the gap between elastomer lip seals and mechanical carbon face seals, particularly in applications where higher pressure, speeds or other harsh conditions go beyond the capabilities of oil seals.
The typical size range is for shaft diameters from .125” (3 mm) to 10” (254 mm).
