HGW 37° JIC fittings are hydraulic adapters designed for flared tube and hose connections using the SAE J514 37-degree flare standard. This category includes straight adapters, elbows, tees, plugs, caps, and conversion fittings for JIC, NPT, ORFS, BSP, and metric hydraulic systems.
A JIC connection seals where two matching 37° metal seats meet. For rigid tubing, the tube end is flared to 37° and secured against the fitting nose with a compatible nut and sleeve. Hose assemblies commonly use a female JIC swivel that mates with a male JIC seat. The threads draw the joint together, while the flare surfaces create the primary seal.
HGW JIC series include straight, 45°, 90°, tee, cross, bulkhead, swivel, cap, plug, nut, and sleeve configurations. Conversion options connect JIC lines to NPTF, ORB, ORFS, BSPP, BSPT, JIS, Komatsu, DIN, metric ED-seal, and ISO 6149 ports, helping one 37° flare system interface with equipment built to different standards.
Materials
HGW JIC fittings are available in steel and stainless steel across many series, with brass offered in selected parts and sizes. Material, plating, dimensions, and pressure rating vary by item; confirm the specifications for the exact part number.
