Steel BSPP Steel Pipe Fittings (NPTF) Steel 37°JIC Flare
Our steel pipe fittings come in many configurations such as 7002 Male Connector BSPP, 7042 Female Adapter BSPP, 7202 90Male BSPP Elbows, and many more. These pipe fittings have BSPP threads, which stands for British Standard Parallel Pipe. Male BSPP fittings that have a 30-degree internal chamfer that make a 60 degree inverted cone, will mate with female BSPP swivel unions.
Our steel pipe fittings come in many configurations such as 5404 male pipe hex nipple, 5000 female pipe coupling, 5404N seamless pipe nipple, and many more. These pipe fittings have NPTF threads, which stands for American Standard Taper Pipe Duel Dryseal Thread, that are designed to screw together and cause interference at the roots and crests of the threads. The thread deformations caused by the interference fit and the wrench tightening is designed to make a dry mechanical seal.
Our steel 37°JIC flare come in many configurations such as 2404 male connector, 2503 45° male elbow, and many more. These hydraulic fittings have NPTF threads. The JIC connection is widely used in hydraulic systems. When the straight threads are engaged, the 37° male seat seals on the 37° female flare seat which allows a complete mechanical seal. JIC fittings are an excellent choice for preventing leaks and can be used for higher pressure applications.
Steel Female Pipe Swivels (NPSM) Steel Straight Thread O-Ring Boss (SAE/ORB)
Our steel female pipe swivels come in many configurations such as 1404 male pipe adapter, 1501 90° male pipe elbow, 1503 45° male pipe elbow, and many more. These pipe fittings have NPSM threads, which stands for National Pipe Straight Mechanical, that are designed to screw together and cause interference at the roots and crests of the threads. The thread deformations caused by the interference fit and the wrench tightening is designed to make a dry mechanical seal. Theses Fittings are not used with liquids.
Our steel SAE straight thread o-ring boss (ORB) come in many configurations such as 6400 straight thread connector, 6801 90° straight thread elbow, and many more. This straight thread connection uses the same threads as the 37° JIC. However the 37° flare has been removed and an o-ring has been added. When mated with a female o-ring boss port the o-ring is trapped in a special tapered counter bore to affect the seal.
