Low-Friction Performance & Chemical Inertia

The Stainless Steel Case PTFE Shaft Seal represents the pinnacle of sealing technology for aggressive industrial processing.
By combining a precision-engineered stainless steel outer shell with a modified PTFE sealing element, this ptfe rotary lip seal achieves structural rigidity that traditional rubber seals cannot match.
The PTFE lip is chemically inert, resisting degradation from nearly all industrial acids, bases, and solvents. This material synergy allows our ptfe rotary seals to operate efficiently at surface speeds exceeding 30 m/s while maintaining a low-friction interface that prevents shaft wear.
The robust metal casing ensures a secure interference fit in the housing, maintaining alignment even under significant thermal expansion or high-pressure cycles.
Why Choose Jinwo - Advanced Material Engineering
Our seals utilize premium stainless steel housings (SS304 or SS316) to ensure zero oxidation and maximum durability in high-humidity or sterile environments.
We optimize the PTFE lip geometry using proprietary turning technology, ensuring that the contact pressure is perfectly balanced for dry-running longevity.
Every batch of the Stainless Steel Case PTFE Shaft Seal is verified for thermal stability, guaranteeing consistent performance across a wide operating window from cryogenic temperatures to extreme heat.
Jinwo partners with B2B clients to provide customized filling recipes (Graphite, Carbon, or Moly) tailored to specific application requirements for air and gas handling.
