Parker PP-00066 Female Swivel Hose Fitting 3/8 Inch Barb

Product Description

The PARKER PP-00066 is a barbed push-on hose female swivel fitting designed for secure, leak-resistant connections in fluid transfer and hydraulic hose assemblies. Machined from brass, this fitting features a 3/8 inch barb that accepts compatible push-on hose and a 5/8-18 UNF female swivel thread for attachment to male-threaded ports. The swivel design allows the hose to be positioned without twisting during assembly, reducing stress on the connection. At 1.44 inches in length, it is a compact fitting suited to tight installation spaces. Plumbers, hydraulic technicians, and HVAC service professionals routinely install this type of fitting in low- to medium-pressure fluid lines.

This fitting is used in residential and light commercial applications where a barbed hose end must connect to a UNF-threaded port. Typical installations include hydraulic hose assemblies, fluid transfer lines, and cooling system plumbing. The brass construction provides corrosion resistance in both water and petroleum-based fluid service. The push-on barb design eliminates the need for clamps in compatible low-pressure hose systems, though clamps may be added for additional retention depending on the application pressure and hose type.

Installation Notes

Installation is performed by plumbers, hydraulic technicians, or HVAC service professionals. Depressurize and drain the fluid system completely before removing or installing any fittings. Inspect the mating male UNF threads for damage before assembly and ensure the hose is fully seated past all barbs before applying system pressure. Follow applicable IPC or system manufacturer guidelines for allowable working pressure with push-on hose assemblies.
