45° Pipe Swivel Elbows | Parker

Pipe swivel connections are one of the most traditional types of hydraulic connections. NPSM swivel adapters add versatility to male NPT hose and adapter connections. They are especially suited for manufacturers and end users that rely on this versatility. As a result, equipment manufacturers can simplify their hose assembly requirements by specifying NPSM adapters. Motion & Flow Control Products, Inc. offers a full line of NPSM pipe swivel adapters. Fourteen configurations are available as standard from Parker, many of which are available in steel and stainless steel. Parker’s pipe swivels are designed for use with male NPT/NPTF hose fittings and adapt­ers with a 30° machined seat.

How Pipe Swivels Work

Pipe swivel adapters are manufactured in accordance to SAE J514 specifications.

Unlike most pipe thread connections, NPSM swivel adapters do not seal on the threads. NPSM swivel connections incorporate parallel threads, as opposed to tapered. Sealing is accomplished between the nose of the swivel and the mating seat of the NPT pipe thread. This creates a metal-to-metal seal.

A mating NPT male connector must have 30° seat to ensure proper sealing. A full internal 30° seat with surface finish requirements of 125 Ra or better is required. See SAE J516 for specific requirements of the 30° seat.

Not all male NPT ends have the 30° seat. Parts that have 30° seat include a note.
