Engineered for demanding hydraulic cylinder applications, this Bronze Filled PTFE Piston Seal Assembly delivers exceptional wear resistance, low friction, and long service life — even under high-pressure, high-cycle conditions. The bronze filler reinforces the PTFE matrix, dramatically improving load-bearing capacity and dimensional stability compared to virgin PTFE seals.
Key Benefits
Superior wear resistance — Bronze fill extends seal life in abrasive and high-load environments
Low breakout friction — Smooth, consistent actuation with minimal stick-slip
Chemically inert — PTFE base resists hydraulic oils, water-glycol fluids, and most industrial media
Wide temperature range — Performs reliably from -65°F to +450°F (-54°C to +232°C)
Bi-directional sealing — Effective in both directions of piston travel
Typical Applications
Hydraulic cylinders (mobile and industrial)
Heavy equipment and construction machinery
Agricultural and forestry equipment
MRO and OEM replacement sealing
Manufactured to AS568 and ISO dimensional standards. Verify bore diameter, groove dimensions, and operating pressure before ordering.
