Keep your mini excavator's hydraulic control valve running leak-free with this replacement spool valve rod seal kit. Designed specifically for 4-block Chinese mini excavator control valves commonly found on 0.8–2 ton machines, this kit delivers everything you need to fully rebuild the spool valve and restore proper hydraulic operation. The kit includes 4 high-pressure black O-rings that provide the primary hydraulic seal, along with 4 white Teflon retaining rings that reduce wear and ensure smooth spool movement within the valve body. If your control valve is leaking around the rod spools, losing pressure, or experiencing drifting functions, these direct-fit seals are the reliable solution to get your machine back in working order. Compatible with standard hydraulic 4-section spool valve blocks found on many OEM and aftermarket mini excavators.
