About This Seal Kit
Komatsu seal kits including the PC200-7 control valve internal kits (LS shuttle, LS select, relief, backup valve, plug and cock seals), swing motor, pilot valve and travel valve seal kits.
The PC200-7 Relief Valve Seals is an OEM-standard aftermarket seal & repair kit for PC200-7. Seals are OEM-standard aftermarket, made in the original dimensions and materials (NBR / PU / PTFE as specified for the application) so they drop into the original gland and piston grooves without modification. The kit covers the wear parts that fail first — wiper, rod seal, buffer, piston seal, wear rings, O-rings and backup rings — so the cylinder is rebuilt once, correctly.
Every unit is inspected and pressure-checked before dispatch and ships with a test report. Stock models leave within 48 hours; non-stock units are typically ready in 5–15 days. Sea, air and express shipping are available worldwide, and our team answers quote requests within 12 hours — usually much faster on WhatsApp.
