6900-20-16 O-Ring to NPTF Pipe Swivel NPSM Adapter

The 6900-20-16 O-Ring to NPTF Pipe Swivel NPSM Adapter is a straight hydraulic fitting designed to connect a 1 5/8-12 Male O-Ring Boss (ORB) (-20) port to a 1-11 1/2 Female Pipe Swivel (NPSM) (-16) connection. This adapter provides a reliable transition between ORB and NPSM thread systems while allowing swivel movement for easier alignment during installation.

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