VIO15-2 Centre Joint Seal Kit Description

The YNF16069 Centre Joint Seal Kit, replacing OEM 172446-73900, is specifically developed for the VIO15-2 mini excavator swivel joint. This seal kit restores the sealing performance of the centre joint—also known as the swivel joint or distribution joint—which is responsible for transferring hydraulic oil between the upper and lower structures of the machine while allowing continuous rotation.

When centre joint seals wear out, machines often experience hydraulic cross-leakage, oil dripping from the lower frame, weakened travel power, and unstable working functions. The YNF16069 kit includes high-quality NBR, PU, and PTFE sealing elements designed for excellent pressure resistance, abrasion resistance, and long service life even under high-cycle usage.

Widely used by hydraulic repair shops, excavator service centres, rental fleets, and aftermarket parts distributors, this seal kit helps restore smooth machine rotation, stable hydraulic flow, and overall operational efficiency.
