Parker PF-00031 Reusable Hose Male Fitting 1/2 in Mnpt

Product Description

The PARKER PF-00031 is a reusable male hose fitting designed for secure, field-serviceable hose terminations in hydraulic and pneumatic fluid-transfer applications. Constructed from brass, it features a 1/2-inch MNPT threaded end and accepts hose with a 3/8-inch inside diameter. The reusable design allows the fitting to be disassembled and reinstalled onto a new hose without special crimping equipment, making it practical for field repairs and low-volume service work. It meets D.O.T. FMVSS571.106 standards and is rated for temperatures from -65 degrees F to 250 degrees F, covering a wide range of operating environments encountered in mobile equipment and industrial service.

This fitting is suited for use in hydraulic hose assemblies, pneumatic lines, and fluid-transfer systems found in mobile equipment, agricultural machinery, construction equipment, and light industrial installations. The 1/2-inch MNPT thread allows it to connect directly to standard pipe-threaded ports and fittings common across these industries. Plumbers, hydraulic technicians, and equipment mechanics working on hose replacement or field repair will find the reusable construction reduces the need for pre-crimped assemblies on short runs or emergency fixes.

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and pneumatic hose assemblies using 3/8-inch ID hose terminated with 1/2-inch MNPT male threaded connections.

Installation Notes

Installation is typically performed by hydraulic technicians or qualified mechanics. Depressurize and isolate the hose assembly fully before disassembling or installing any hose fitting. Follow the fitting manufacturer assembly instructions for proper insert and socket engagement; hand-tighten the threaded components and use appropriate wrenches to achieve a leak-free seat without over-torquing brass threads. Inspect the hose cut end for squareness and the hose ID for damage before reuse of this fitting.
