3 Introduction 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. See Fig. H for an illustration of this product flexibility. Parker offers a full line of NPSM pipe swivel adapters. Parker s product line is known as 07 Adapters. Fourteen configurations are available as standard, many of which are available in steel and stainless steel. 07 adapters are designed for use with male NPT/NPTF hose fittings and adapters with a 30 machined seat. Adapter Port Connection Design and Construction Pipe swivel adapters are manufactured in accordance to SAE J54 specifications, and thus are designed to work in conjunction with several manufacturers hose and adapter products. 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 as shown in Fig H. Thus a mating NPT male connector must have this 30 seat to ensure proper sealing. A full internal 30 seat with surface finish requirements of 5 Ra or better is required. See SAE J56 for specific requirements of the 30 seat. NPSM / NPT Union Fig. H Illustration of the flexibility of the NPT Port and Hose Adapter system Construction: Shaped 07 adapters are manufactured from a hot forged construction. Straight adapters and crimp nuts are manufactured from cold drawn barstock. All Parker 07 with male NPT ends include a 30 machined seat for NPSM swivel connections. Threads: NPTF: ANSI B.0., FED-STD-H8/7 NPT: SAEJ476, ANSI B.0.3, FED-STD-H8/8 NPSM: ANSI B.0., FED-STD-H8/7 *UN/UNF: ANSI B., FED-STD-H8/ (*Class A or B) Materials Specifications 07 adapters are manufactured using state-of-the-art equipment and manufacturing technologies to assure construction integrity, highest strength, long service life and the highest quality. These materials are shown in Table H. Upon request, 07 fittings can be furnished in materials, sizes and configurations other than Parker s standard offering.
