Ask A Question

Description & Features

Manufactured from straight steel, the #2 FP x #4 FP Swivel is a straight hydraulic adapter rated for dynamic pressures up to 6,000 PSI. It connects a 1/8-27 Female NPTF thread (conforming to SAE J476) on one end to a 1/4-18 Female NPSM Swivel thread (conforming to SAE J514) on the other, making it well suited for applications where rotational flexibility at the swivel end is needed to reduce stress on connected lines.

Part of the Brennan Industries Series 1405, this fitting is a reliable choice for hydraulic systems requiring a transition between NPTF and NPSM swivel connections. The swivel end allows the fitting to rotate during assembly or in service, helping to prevent line twist and mechanical strain at the connection point.
