Jiayuan fittings offer a series of caps, plugs, Union, coversion adapters to mate with this Komatsu end connections, body shape as Straight adapters, Elbow Adapters, Adjustable adapters etc.

The Komatsu style connection is generally rated at 4000 psi (280kg/cm 2 or 27.5 Mpa), thy are rated at the full pressure rating in sizes 4-16, with slight pressure reductions in the less common sizes of -20 and -24.

Komatsu style adapters allow for more aftermarket flexibility. Jiayuan’s caps and plugs enable technicians to protect critical sealing surfaces of hoses and adapters from damage and contamination. This protection is important during testing, repair and/or implement installation and removal.

Jiayuan’s line of Komatsu style fitting is sold only as a hose adapter and thus tube nuts and sleeves are not available. The adapter consists of a single body. The mating hose swivel mates directly to the 30°nose of the adapter, as shown in Fig. J1. This simple, metal-to-metal connection provides a very effective seal between the fitting nose and the hose swivel seat.

1) 30°nose flare

2) Metric threads with 1.5 mm pitch

3) Used only as a hose adapter

4) Heavy duty crimp nut for higher assembly torque
