6900-08-04 O-Ring to NPTF Pipe Swivel NPSM Adapter

6900-08-04 O-Ring to NPTF Pipe Swivel NPSM Adapter

The 6900-08-04 O-Ring to NPTF Pipe Swivel NPSM Adapter is a straight hydraulic fitting designed to connect a 3/4-16 Male O-Ring Boss (ORB) (-08) port to a 1/4-18 Female Pipe Swivel (NPSM) (-04) connection. This adapter provides a reliable transition between ORB and NPSM thread systems while allowing swivel movement for easier installation and alignment.

Manufactured from high-strength steel and compliant with SAE 140157, this fitting is built for durability, pressure resistance, and long service life in hydraulic and fluid transfer systems. The ORB end ensures secure O-ring sealing, while the swivel NPSM end helps reduce hose twist and installation stress.
