PC220-8 Main Control Valve Seal Kit Description

The YNF17396 PC220-8 Main Control Valve Seal Kit provides all necessary sealing components to rebuild the main control valve of PC220-8 excavators. Over time, valve seals degrade due to continuous hydraulic cycles, pressure fluctuations, and oil contamination, resulting in internal leakage, reduced hydraulic performance, or imprecise control.

This kit includes premium O-rings, spool seals, gasket seals, and backup rings made from high-quality PU, NBR, PTFE, and rubber compounds. These materials ensure long-lasting performance, high pressure tolerance, and reliable sealing even in harsh working conditions.

Trusted by service workshops, fleet operators, and aftermarket distributors, the YNF17396 seal kit restores precise hydraulic flow, stabilizes valve performance, minimizes downtime, and prolongs the lifespan of excavator hydraulic systems.
