HBW buffer seal is a vital hydraulic sealing component specially designed for hydraulic cylinders to absorb pressure impact and buffer sudden pressure peaks during reciprocating operation. Installed before the main rod seal, it relieves instantaneous high pressure effectively and protects the primary sealing set from damage caused by hydraulic shock, greatly extending the service life of the whole sealing system.
Made of high-quality polyurethane material with optional PA back-up ring, HBW buffer seal features excellent wear resistance, extrusion resistance and low friction coefficient. Its unique pressure relief groove structure can discharge trapped pressure rapidly, preventing pressure buildup between buffer seal and main seal. It performs reliably under heavy load and frequent reciprocating motion, compatible with most common hydraulic oils. Suitable for construction machinery, mining equipment, hydraulic presses and other heavy-duty hydraulic systems.
We supply standard-size HBW buffer seals and accept custom machining according to customer drawings. Every product undergoes strict dimensional inspection and performance testing to guarantee stable sealing effect and low leakage rate. Our HBW series buffer seals help equipment reduce maintenance frequency and cut operation costs. We support bulk wholesale and fast delivery, serving hydraulic equipment manufacturers, seal distributors and maintenance partners worldwide.
