High-pressure seal kit for PC270-8 main control valve, restoring hydraulic sealing and stable control valve performance.
OEM-matched 723-47-23302K control valve seal kit
Designed for Komatsu PC270-8 main control valve
Includes O-rings, gaskets, wear rings, and high-pressure seals
Manufactured with heat-resistant, oil-resistant sealing materials
Restores hydraulic stability and prevents internal leakage
The YNF13960 Main Control Valve Seal Kit, replacing OEM 723-47-23302K, is specifically engineered for the Komatsu PC270-8 excavator. The main control valve manages multiple hydraulic circuits including boom, arm, bucket, and swing systems. When internal seals wear out, leakage, pressure loss, drifting, weak hydraulic response, or mixed-actuation issues often occur.
This complete seal kit contains all necessary high-pressure O-rings, gaskets, backup rings, wear rings, and sealing components used in the control valve’s spool chambers and hydraulic passages. Made from high-strength PU, nitrile rubber, and heat-resistant sealing materials, the kit maintains performance even under high temperature and continuous heavy-duty operation.
Ideal for hydraulic repair workshops, fleet maintenance teams, and aftermarket distributors, the YNF13960 kit provides a cost-effective and reliable solution for restoring PC270-8 hydraulic control valve sealing and machine performance.
