*GETTING RID OF OLD INVENTORY*

NEW LOW PRICE

This replacement spool valve rod seal kit is designed specifically for 4-block Chinese mini excavator control valves. The kit includes 4 high-pressure black O-rings and 4 white Teflon retaining rings, providing all the essential sealing components needed to rebuild and stop leakage around the spool valve rods.

These seals are commonly used in 0.8–2 ton Chinese mini excavators and fit the standard hydraulic 4-section spool valve block found on many OEM and aftermarket machines. The O-rings provide the primary hydraulic seal, while the Teflon retaining rings support durability, reduce wear, and ensure smooth spool movement within the valve body.

If your control valve is leaking around the rod spools, losing pressure, or showing drifting functions, these seals are the direct-fit solution to restore proper hydraulic operation.
