Manufacturer Customized U601 U603 Hydraulic Jack Oil Seal Polyurethane UN PU Piston Rod Seals for cylinders.
KLHPS-01 is a high-performance single-acting U-rod or piston all-purpose seal that provides the driest seal in light and medium-load applications. The seals are injection molded with high performance U5203 material, easy to install and excellent low temperature resistance. When used in conjunction with a full-coverage retainer, the seal may be considered for heavy-duty applications. Unique design seal lip angle provides optimal sealing performance.
