Parker 222P-12-12 Pipe Adapter 3/4 in Mnptf X Fnptf Brass

Product Description

The PARKER 222P-12-12 is a brass pipe adapter designed to connect male and female National Pipe Taper Fuel threads in hydraulic, pneumatic, and fluid transfer systems. It features a 3/4 inch MNPTF on one end and a 3/4 inch FNPTF on the other, providing a reliable threaded transition in a single compact fitting. Rated to 1,000 psi maximum working pressure, it handles demanding service conditions across a wide temperature range of -65 degrees F to 250 degrees F. Machined from brass, it offers good corrosion resistance in fuel, oil, water, and air service. This fitting is sized at the 3/4 inch thread class and meets SAE J530 and SAE J531 standards.

This adapter is suited for industrial plumbing, hydraulic lines, fuel systems, and compressed air installations where a male-to-female NPT transition is needed. Common applications include equipment manifolds, pump connections, and panel-mount fittings in both stationary and mobile machinery. It is appropriate for residential, commercial, and light industrial settings where a brass NPT adapter meets the pressure and temperature requirements of the system.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanic familiar with threaded pipe fittings and applicable codes. Shut down and depressurize the system completely before removing or installing any fittings. Apply thread sealant or PTFE tape appropriate for the fluid service to the male threads before assembly. Do not overtighten; use a calibrated torque wrench and follow system manufacturer guidelines for thread engagement.
