DANFOSS / EATON 1 MNPT X 1 FNPT SWV

Description & Features

Designed for rotational fluid transfer in hydraulic systems, the Danfoss / Eaton FS59004-1616-75 is a 1-inch swivel joint from the FS5900 Series, connecting a 1 MNPT end to a 1 FNPT end. Both connections are NPTF-threaded, providing a leak-resistant dry-seal interface suitable for demanding industrial applications. The unit is constructed from steel and carries a minimum working temperature rating of -20°F, making it suitable for use in cold-environment installations.

Part of Eaton's Aeroquip-branded lineup, this swivel joint allows relative rotation between connected lines, reducing stress and accommodating movement or misalignment in hydraulic circuits. With a hex size of 1.44 inches on the male end and a 1-inch swivel size, it is straightforward to install using standard tooling. The package weight is 0.5 lb, and the unit ships individually.
