Supreme medium-pressure single-lip rotary shaft seal
Medium-pressure single-lip oil seal with integrated seal lip support and proprietary blends of PTFE bonded onto the dynamic sealing lip.
The combination of integrated lip support, reduced lip load, premium Duralast™ material, and low friction PTFE lip leads to reduced friction, lower heat build up and wear; this in turn results in increased seal life under higher pressures and speeds. This allows the seal to handle higher operating pressure. The rubber-covered OD of the seal creates a tight seal with the housing bore, and the press-in fitment design accommodates housings with short axial space requirements. For dirty, dusty or polluted environments, our ASHP5 style with additional dust lip should be used.
