The PARKER 1 MMS-S is a male branch tee fitting designed for industrial pipe systems requiring a reliable three-way connection. It features a 1-inch male NPT thread (MNPTF) on the run ends and a 1-inch female NPT thread (FNPTF) on the branch port, allowing straight-run pipe flow with a threaded female branch takeoff. Constructed from zinc-plated steel, this fitting handles a maximum working pressure of 1,800 psi, making it suitable for high-pressure hydraulic, pneumatic, and fluid transfer applications. Licensed plumbers, pipefitters, and mechanical contractors typically install this fitting in industrial and commercial piping systems.
This fitting is used in industrial and commercial pipe assemblies where a branch connection must be added to a threaded run. The MNPTF x FNPTF configuration allows the fitting to thread directly onto male-threaded pipe on both run ends while accepting a male-threaded branch connection on the female port. Common applications include compressed air distribution, hydraulic fluid lines, and general industrial fluid handling systems where steel construction and high-pressure ratings are required.
Designed for use with 1-inch NPT-threaded steel pipe in industrial fluid and pneumatic systems rated to 1,800 psi or below.
Installation should be performed by a qualified pipefitter or licensed plumber in accordance with applicable mechanical codes. Depressurize and isolate the line completely before disassembly or fitting installation. Apply a compatible thread sealant or PTFE tape to all male threads before assembly, and tighten to hand-tight plus the appropriate number of turns for the thread size per standard practice. Do not over-tighten, as this can crack or deform threaded connections.
