Double Coated PTFE O Ring Industrial Sealing
A: A precision-engineered sealing solution featuring a PTFE (Teflon®) outer layer bonded to an elastic inner core (typically silicone or FKM). This dual-layer design merges PTFE’s extreme chemical/thermal resistance with core flexibility, eliminating compression set issues in static/dynamic seals.
A: The dual-coating technology solves 3 critical challenges:
✅ Zero Leakage – PTFE’s near-zero friction surface prevents glandular micro-gaps.
✅ Longevity – Resists degradation from acids, solvents, and 260°C+/500°F temps.
✅ Adaptability – Inner core maintains seal force under vibration/thermal cycling.
A: Ideal for ultra-demanding environments:
➠ Semiconductor etch tools (HF acid resistance)
➠ Pharma CIP/SIP processes (steam sterilization)
➠ High-speed rotary unions (low friction = energy savings)
➠ Aerospace fuel systems (wide thermal range:-50~250℃
