Features & Benefits
PTFE NBR Hydraulic Buffer Seal combines low-friction PTFE with elastic NBR, helping a buffer seal hydraulic system reduce wear and improve sealing performance.
The design effectively absorbs pressure spikes, extending component life and maintaining stable operation in demanding hydraulic applications.
As an hby buffer seal, it minimizes leakage while supporting smooth rod movement and improved equipment efficiency.
The optimized sealing profile enhances resistance to abrasion, extrusion, and pressure fluctuations over long service periods.
This rod buffer seal is suitable for various hydraulic systems requiring reliable sealing and reduced maintenance costs.
Installation Guide
Before installation, clean the groove, rod, and housing thoroughly to prevent contamination from affecting the hydraulic buffer seal.
Inspect all components for scratches, burrs, or damage that could shorten seal service life.
Lightly lubricate the seal and installation surfaces to ease fitting and reduce assembly stress.
Carefully position the hydraulic cylinder buffer seal into the groove without twisting or overstretching the material.
After fitting the hby seal, verify alignment and perform a pressure test to ensure proper sealing performance.
Compatibility & Procurement
PTFE NBR buffer seals are compatible with many mineral oil-based hydraulic fluids used in industrial equipment.
A properly selected seal buffer can improve sealing reliability in construction machinery, presses, and mobile hydraulics.
The buffer seal hydraulic cylinder application requires accurate groove dimensions and operating pressure evaluation.
Buyers should confirm material compatibility, temperature range, speed, and pressure requirements before ordering.
For optimal performance, source seals from reliable suppliers that provide technical support, quality control, and consistent product availability.
