JOINT(S,G1/8-G1/4) (KU-RB23861490)
Description:
The Genuine Kubota JOINT (S, G1/8-G1/4) (Part No. RB238-61490 / KU-RB23861490) is an OEM hydraulic pipe joint designed for compatible Kubota mini excavators and compact construction equipment. This precision-made connector provides a secure transition between G1/8 and G1/4 threaded hydraulic connections, allowing proper routing and connection of hydraulic lines and components.
Manufactured to Kubota’s original equipment specifications, this genuine replacement joint ensures correct thread dimensions, sealing performance, and installation fit. It is designed for use in hydraulic piping assemblies where reliable fluid connection and leak prevention are essential.
Hydraulic joints operate under pressure and are exposed to vibration, temperature changes, and continuous machine operation. A worn, damaged, or leaking joint can result in hydraulic fluid loss, reduced system efficiency, and potential component damage. Replacing the fitting with a genuine Kubota part helps restore proper hydraulic circuit performance.
