Product Introduction
Long‑life PTFE hydraulic piston seals are high‑performance composite sealing components for heavy‑duty hydraulic cylinders. Made of filled‑PTFE sealing ring paired with NBR or FKM elastomer energizer, they are precision‑machined for reciprocating dynamic sealing. Core strengths cover ultra‑low friction, outstanding wear‑resistance and anti‑extrusion capacity, effectively eliminating stick‑slip movement. Featuring great chemical inertness and broad temperature adaptability, they maintain stable bidirectional sealing under high‑pressure harsh working conditions and extend equipment service cycles. Widely adopted for construction machinery, hydraulic presses, mining equipment and general‑industrial hydraulic systems. Multiple standard sizes are in stock. Custom dimensions, filled‑PTFE formulas and OEM service are available according to drawings, samples or groove sizes to satisfy diverse engineering requirements.
