Bronze Filled PTFE Hydraulic Piston Seal Assembly

Bronze Filled PTFE Hydraulic Piston Seal Assembly

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.
