Engineered for demanding hydraulic applications, this Bronze Filled PTFE Rod Buffer Seal delivers exceptional load-bearing capacity and low-friction performance. The bronze filler reinforces the PTFE matrix, providing superior dimensional stability and wear resistance under high-pressure, high-cycle conditions — making it the preferred choice for heavy-duty industrial and mobile hydraulic cylinders.
Key Features
Bronze-Filled PTFE Construction: Enhanced compressive strength and creep resistance compared to virgin PTFE, ideal for high-load rod applications
Low Friction: PTFE base material ensures minimal stick-slip and smooth rod movement, reducing seal wear and extending service life
Buffer Seal Function: Absorbs pressure spikes and protects the primary rod seal from peak hydraulic loads, significantly extending overall seal system life
Wide Temperature Range: Performs reliably from -65°F to +500°F (-54°C to +260°C)
Chemical Resistance: Compatible with most hydraulic fluids including mineral oil, synthetic fluids, water-glycol, and phosphate esters
Buffer seals are installed in the rod gland ahead of the primary wiper and rod seal. They are designed to handle dynamic pressure surges rather than continuous full system pressure. Verify groove dimensions and rod diameter before ordering.
