Choose stainless steel adapters such as stainless steel NPT fittings ( NPT/NPSM pipe swivel), SAE J514-37 degree JIC fittings, O-Ring Boss (ORB), O-Ring Face Seal (ORFS), British and Metric (BSPP/BSPT), and ultra high pressure stainless steel fittings.
Pipe Thread (NPT) - Stainless Steel Female Pipe Swivel (NPSM) - Stainless Steel

Pipe fitting steel adapters use a NPTF (National Pipe Tapered, Fuel / equivalent to NPT National Pipe Taper) thread to mate male NPT to female pipe thread (parallel NPSM and tapered NPT.

Pipe female swivel or NPSM (National Pipe Straight Mechanical) female steel adapter fittings use a straight parallel thread with a 30° cone seat to mate to a male NPT/NPTF pipe fitting with a matching chamfer.

37 Degree JIC / AN - Stainless Steel O-Ring Face Seal (ORFS) - Stainless Steel

SAE J514 37° Degree steel adapter fittings use a 37° flare chamfer to provide an excellent mechanical seal between the male and female adapter.

Stainless Steel O-Ring Face Seal (ORFS) steel adapter fittings are the most recent adapter family designed to provide the ultimate in leak proof protection. These Stainless Steel SAE J1453 adapters use an o-ring in the face to create a strong seal.
British & Metric Thread - Stainless Steel SAE O-Ring Boss (ORB) - Stainless Steel

BSP British Standard Pipe Thread: BSPP (Parallel Thread) and BSPT (Tapered Thread) as well as a full offering Metric thread (DIN spec) are offered in 316 Stainless steel.

SAE O-Ring Boss (ORB) steel adapter fittings use a SAE J514 straight thread with an O-ring at the adapter base for a tight seal connection.

Flange Components - Stainless Steel Ultra High Pressure - Stainless Steel

Flange steel adapter fittings are held in place with four bolts and conform to SAE J518 code 61 (3000 psi) and code 62 (6000 psi) for high pressure hydraulic applications.

Stainless Steel Pipe fittings use a NPT thread to mate male to female pipe thread.
