Transparent White UPE Material PTFE Spring Energized Seal
Embedded Stainless Steel Spring Ensures Reliable Sealing in Normal & Vacuum Environments
The Transparent White UPE Spring Energized Seal is a high-reliability precision sealing component. It features a transparent white ultra-high molecular weight polyethylene (UPE) body—boasting superior wear resistance, self-lubrication, and corrosion resistance—paired with an embedded stainless steel spring.
The spring delivers steady initial preload for tight sealing in normal pressure and vacuum, while UPE’s low-temperature durability (functional at liquid nitrogen temperatures) and non-toxic, hygienic traits meet strict safety needs.
Ideal for food, medical, chemical, and aerospace sectors, it prevents leakage, cuts friction-related energy loss, and ensures long-term performance in harsh or variable conditions.

1. Product Advantages
Crafted by Forever Seals, this seal leverages UPE (Ultra-High Molecular Weight Polyethylene) for unmatched performance: top-tier wear resistance (8x that of plain carbon steel), inherent self-lubrication to reduce friction, and strong corrosion resistance against harsh media. It’s non-toxic, hygienic (meets food/medical safety standards), and retains ductility at liquid nitrogen temperatures—ensuring durability in extreme conditions.
2. Working Principle
The seal combines a UPE body with an embedded stainless steel spring. The spring provides initial preload for tight contact in normal pressure and vacuum environments; as system pressure rises, the UPE cavity’s pressure pushes the seal lip closer to the surface, maintaining leak-proof sealing across pressure fluctuations.
3. Product Details
Material: Transparent white UPE (main body) + stainless steel (spring)
Key Traits: Low friction coefficient, no lubrication dependency, long service life
Design: Compact structure, easy to install in precision equipment
4. Application Range
Ideal for Forever Seals’ target sectors:
Food industry (beverage filling lines)

Chemical field (corrosive medium pipelines)
Aerospace (hydraulic/pneumatic systems)
5. FAQ
Q: Is this seal suitable for vacuum environments?
A: Yes—its spring-driven preload ensures reliable sealing in vacuums.
Q: Can it be used in food contact applications?
A: Absolutely; UPE’s non-toxic, hygienic properties meet global food safety standards.
