HBY Buffer Seal HBT Step Seal 95*110.5*6 PU Buffer Rod seal
Description
1)The most important thing of the buffer seal is to fully lubricate the main seal, which can assist the main oil seal to increase the pressure without causing a pressure trap between itself and the main seal.
2) HBY Buffer Seals are used as buffer rings along with secondary U-Cup type seals. The anti-extrusion ring protects the rod sealing area from pressure spikes and the notched lip allows a pumping-back action suppressing any pressure-trap effect.
