PTFE Back-up Rings are essential components in high-pressure sealing systems, designed to reinforce primary seals like O-rings and prevent extrusion under extreme mechanical stress. Engineered from polytetrafluoroethylene (PTFE), these rings exhibit exceptional chemical inertness, resisting virtually all aggressive media including strong acids, strong alkalis, organic solvents, and corrosive gases. Their ultra-low friction coefficient and outstanding dimensional stability enable reliable performance in dynamic applications with temperatures ranging from -200°C to +260°C. The material's high compressive strength and non-deformable characteristics ensure optimal load distribution, effectively protecting elastomeric seals from blow-out or damage during pressure fluctuations. With inherent non-stick properties and FDA/USP Class VI compliance where required, PTFE Back-up Rings are widely utilized in critical industries such as oil and gas wellhead equipment, chemical processing reactors, hydraulic systems, and pharmaceutical machinery demanding contamination-free operation. Their combination of chemical imperviousness and mechanical resilience makes them indispensable for maintaining seal integrity in harsh operating environments.

PTFE Stainless Steel Oil Seals offer a robust sealing solution with an inner wall featuring grooves that create an inward thrust, enhancing the seal's retention. Made with a top-grade PTFE material, these seals are ideal for oil-free operations, providing immediate low-friction performance post-restart. The use of high-strength, wear-resistant hardware ensures long-term durability without rust. An integrated oil return line in the design boosts sealing performance. Suitable for a variety of applications including compressors, motors, and food processing equipment, these seals are a reliable choice for harsh environments.
