1. Product Advantages
Exceptional Durability: Crafted with UPE (Ultra-High Molecular Weight Polyethylene), our seals boast 5–10 times higher wear resistance than PTFE, ensuring long service life and reducing maintenance frequency.
Superior Sealing Performance: The corrosion-resistant stainless steel spring delivers initial pre-pressure for zero-pressure sealing, while system pressure amplifies lip contact—guaranteeing leak-proof operation even under fluctuating pressures.
Wide Temperature Adaptability: Operates reliably from -200℃ to +93℃ (short-term use up to +120℃), suitable for extreme industrial environments.
Low Friction & Safety Compliance: UPE’s self-lubricating surface eliminates “stick-slip” issues; meets FDA 21CFR Part 177 and BGA standards, making it safe for food and pharmaceutical applications.
Flexible Customization: CNC-machined for non-standard sizes with no mold costs, fitting small-batch or specialized needs.
2. Working Principle
Our UPE Spring Energized Seals feature a two-part structure: a UPE sealing ring and a stainless steel spring. At zero system pressure, the spring provides constant pre-pressure to press the UPE lip tightly against the sealing surface. As pressure increases, the UPE U-shaped cavity fills with media, pushing the lip further against the contact surface—creating a dynamic, pressure-enhanced seal that maintains integrity across pressure cycles.
3. Product Details

5. FAQ
Q: Can these seals be used for high-temperature sterilization?
A: Yes—short-term exposure to +120℃ allows for high-temperature sterilization, suitable for pharmaceutical cleaning processes.
Q: Do you offer samples?
A: Yes, we provide free samples for standard sizes; custom samples are available with a small fee.
Q: What is the shelf life of the seals?
A: UPE’s stability ensures an unlimited shelf life when stored in a cool, dry environment.
