Parker PP-00388 Hydraulic Hose Swivel Fitting 3/8 Inch

Product Description

The PARKER PP-00388 is a steel swivel fitting designed for hydraulic hose assemblies. It uses a Seal-Lok face seal connection to provide leak-resistant performance in high-pressure hydraulic circuits. The fitting accommodates a 3/8 inch hose diameter and is threaded at 11/16-16. Swivel-style construction allows the hose to be positioned without twisting the assembly during installation or service. This type of fitting is installed by hydraulic system technicians and industrial mechanics working on mobile equipment, machinery, and fluid power systems.

This fitting is suited for use in hydraulic systems requiring a reliable face seal termination at the hose end. Typical applications include mobile hydraulic equipment such as skid steers, excavators, lifts, and agricultural machinery, as well as stationary industrial hydraulic power units. The Seal-Lok configuration is compatible with SAE straight thread O-ring face seal port connections. Installation is performed by qualified hydraulic technicians during hose assembly fabrication or field repair.
