Main Control Valve Seal Kit 7234720401 Description

The YNF17502 7234720401 Main Control Valve Seal Kit contains all essential sealing components required to rebuild excavator main control valves. Over time, hydraulic valve seals degrade due to high pressure, continuous operation, and oil contamination, leading to internal leakage, reduced hydraulic response, or abnormal valve operation.

This kit includes premium O-rings, piston seals, gasket seals, and backup rings made of high-quality PU, NBR, PTFE, and durable rubber compounds. These materials provide excellent durability, high-pressure resistance, and reliable performance under demanding working conditions.

Trusted by service workshops, fleet operators, and aftermarket distributors, the YNF17502 seal kit restores valve sealing, stabilizes hydraulic control, minimizes downtime, and prolongs the lifespan of excavator hydraulic systems.
