Product Introduction

This NBR/FKM hydraulic seal repair kit is professionally customized for excavator main control valves, specially designed to fix internal leakage, pressure loss, slow response and jitter problems of control valves.

With OEM precision size and perfect fitting performance, the kit effectively eliminates internal oil leakage and circuit series flow, stabilizes hydraulic pressure and flow, and restores accurate and flexible operation of excavators. Complete in specifications and easy to install, it supports fast valve maintenance, reduces downtime and repair costs, and ensures long-term stable and precise operation of the excavator hydraulic control system.
