JIS Fitting

JIS hydraulic fittings are specifically engineered to match Japanese Industrial Standards (JIS B 8363), commonly found on Komatsu, Toyota, and other Asian heavy machinery. Featuring unique 30-degree male flares or 30-degree inverted female seats with metric or BSP threads, our JIS hydraulic adapters ensure exact OEM compatibility, high structural integrity, and long-term reliability for construction and earthmoving equipment.
