Hydraulic Oil Seal: Wear-resistant and durable piston seal (140*150*6) yellow rod oil seals. The KLHPS-04 is a high-performance single-acting U-rod or piston all-purpose seal that provides the driest seal in light and medium-load applications. Injection molded with high-performance U5203 material, it is easy to install and offers excellent low-temperature resistance.
When used in conjunction with a full-coverage retainer, the seal may be considered for heavy-duty applications. The unique design seal lip angle provides optimal sealing performance.
