Parker PP-00351 Female Jic 37 Swivel Fitting 1/2 in

Product Description

The PARKER PP-00351 is a straight female JIC 37-degree swivel fitting designed for hydraulic hose assemblies. It connects a 1/2-inch hydraulic hose to a 9/16-18 female JIC threaded port using a 37-degree flare seating surface, which provides a leak-resistant metal-to-metal seal. The swivel design allows the fitting to rotate during installation, reducing hose twist and making final torque-up easier in tight-access plumbing runs. This fitting is used by hydraulic technicians and fluid-power mechanics assembling or repairing mobile and industrial hydraulic circuits.

This fitting is suited for hydraulic hose assemblies in mobile equipment, industrial machinery, and fluid-power systems where a straight female JIC termination is required. The 9/16-18 thread size and 1/2-inch hose ID make it a common size in medium-pressure hydraulic circuits. It is sold in package quantities of five, making it practical for shop stock or multi-point assembly jobs. Applications span construction equipment, agricultural machinery, and plant hydraulic systems.

Key Features

• 37-degree JIC flare provides a reliable metal-to-metal seal at the connection point
• Swivel design reduces hose twist during installation and final assembly
• Straight orientation simplifies in-line hose-to-port connections
• Fits 1/2-inch hose ID with a 9/16-18 female JIC threaded end
• Packaged in quantities of five for shop stock efficiency

Compatibility

Designed as a standard JIC 37-degree swivel fitting for use with 1/2-inch hydraulic hose and 9/16-18 female JIC ported connections in hydraulic fluid-power systems.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic. Depressurize and bleed down the hydraulic circuit fully before removing or installing any fitting. Inspect the 37-degree flare seating surface on both the fitting and the mating port for nicks or damage before assembly. Do not use thread sealant tape on JIC flare fittings, as the seal is made at the flare cone, not the threads.
