Product Introduction
High‑performance PTFE piston ring seals are precision dynamic sealing components for reciprocating piston systems. Manufactured by moulding, sintering and CNC machining, they adopt virgin or filled‑modified PTFE compound with fillers like carbon, graphite or glass fibre to boost wear‑resistance and anti‑creep performance. Core advantages include ultra‑low friction, self‑lubrication without extra oil supply, excellent chemical inertness and wide temperature adaptability. They deliver stable gas‑liquid sealing and minimize friction loss for piston‑cylinder assemblies. Ideal for oil‑free air compressors, pneumatic cylinders, vacuum pumps and general‑industrial reciprocating equipment. Multiple standard sizes are available in stock. Custom dimensions, PTFE filling formulas and OEM service can be provided according to drawings, samples or cylinder groove parameters to satisfy diverse industrial sealing demands.
