Description
Custom PTFE Spring Seals Polytetrafluoroethylene – U-Shaped Spring Seal Rings & PTFE (Teflon) High-Pressure Oil Seals
We specialize in custom PTFE (Teflon) spring seals, including U-cup rings and high-pressure oil seals. Our tailor-made solutions combine premium PTFE properties with spring-energized design, excelling in high-pressure, corrosive and extreme-temperature environments where standard seals underperform.
Made of high-purity PTFE with optional fillers (carbon/glass fiber, bronze) for wear resistance, these seals are chemically inert to acids, solvents and oils. Equipped with stainless steel/Inconel springs, they ensure reliable sealing even at low pressure, while the U-cup profile optimizes dynamic performance for reciprocating/rotating applications (up to 50 MPa).
As a professional custom manufacturer, we offer full customization—dimensions, spring material, PTFE filler ratios—to match your equipment. CNC-machined with tight tolerances, our seals ensure perfect fit for hydraulic systems, chemical pumps, high-pressure valves and more.
Our seals perform in -200℃ to 260℃, adapting to cryogenic and high-heat scenarios. PTFE’s low friction reduces mating surface wear, extending equipment life. They also resist aging, ozone and UV, ensuring durability in harsh industrial settings.
We follow ISO 9001 standards, with each seal undergoing pressure testing, temperature cycling and dimensional checks. Our expertise in PTFE solutions includes technical support, delivering cost-effective, high-performance custom products.
