Thread data for 7 standards: JIC, NPT, BSP, ORFS, DIN, JIS, SAE ORB

JIC 37° Flare The most common hydraulic fitting in North America. 37-degree flare, straight threads, reusable without replacing seals. NPT / NPTF Tapered pipe threads found everywhere in plumbing and pneumatics. Seals by thread deformation. Not reliably reusable. BSP (BSPP / BSPT) The international counterpart to NPT. 55-degree Whitworth thread angle. NOT interchangeable with NPT despite similar sizes. ORFS O-Ring The leak-proof fitting. O-ring seals on a flat face. Best for high vibration and zero-leak requirements. More expensive than JIC. DIN 2353 (Metric Bite) European standard bite-type fittings. Metric threads with a 24-degree cone and cutting ring. Common on German and Scandinavian machinery. JIS B 2351 Japanese standard fittings. 30-degree flare with metric threads. Found on Komatsu, Kobelco, Hitachi, and other Japanese equipment. SAE ORB Straight-thread O-ring port fitting. The most common hydraulic port standard in North American mobile and industrial equipment.

About This Data

Welding sources

AWS filler metal specifications.

Electrode specs, mechanical properties, and amperage ranges from AWS A5.1, A5.4, A5.9, A5.10, A5.18, A5.20, and A5.29. Preheat data follows AWS D1.1, D1.2, and D1.6.

Fitting sources

SAE and ISO thread standards.

Hydraulic fitting thread dimensions reference SAE J514, ISO 8434, DIN 2353, and JIS B 2351. Seal types and torque specs from manufacturer engineering data.

Operational data

Manufacturer technical data sheets.

Gas flow rates, wire feed speeds, and setup recommendations from Lincoln Electric, Hobart, and ESAB technical publications. All data verified against published standards.
