KMX15YB Valve Seal Kit Description

The YNF17334 KMX15YB Main Control Valve Seal Kit is designed to restore hydraulic sealing performance for the KMX15YB main control valve used in various excavators. The main valve distributes hydraulic flow to major functions including boom, arm, bucket, and swing circuits. When seals deteriorate due to pressure cycling, heat, or contamination, operators may experience internal leakage, weak hydraulic pressure, unstable machine response, or mixed movements.

This seal kit includes high-grade O-rings, wear rings, dust seals, and backup rings made from PU, NBR, PTFE, and heat-resistant rubber compounds. These materials ensure excellent compression resistance, chemical compatibility, and long operational stability.

Trusted by hydraulic repair centers, machinery fleets, and aftermarket distributors, YNF17334 provides a cost-effective, durable solution for full KMX15YB valve overhaul, restoring the excavator’s hydraulic efficiency and reducing downtime.
