Parker 1/4 Mms-s Male Branch Tee 1/4 Inch Mnptf Fnptf

Product Description

The PARKER 1/4 MMS-S is a male branch tee fitting designed for high-pressure industrial pipe assemblies. It connects one male NPT thread to two female NPT threads in a tee configuration, allowing a branch line to be added to an existing pipe run without additional adapters. Constructed from zinc-plated steel, the fitting carries a maximum working pressure of 5,000 psi, making it suitable for hydraulic, pneumatic, and instrumentation lines where pressure integrity is critical. Licensed plumbers, pipefitters, and hydraulic technicians install this type of fitting in both shop fabrication and field service applications.

This fitting is used in industrial fluid and gas distribution systems where a branch connection must be introduced at a 90-degree angle off a main line. Both the male and female threads are 1/4 inch NPTF, conforming to SAE standard 140425. The tee configuration suits tight-quarters installations in machinery, compressor stations, hydraulic power units, and similar equipment where a compact, all-steel connection is required.

Key Features

• 5,000 psi maximum working pressure rated for demanding hydraulic and pneumatic service
• MNPTF x FNPTF thread configuration enables direct branch connections without additional adapters
• Zinc-plated steel construction provides corrosion resistance in industrial environments
• 1/4 inch male and female thread sizes on all ports for consistent line sizing
• Conforms to SAE 140425 standard for NPTF fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4 inch NPTF threaded pipe systems operating up to 5,000 psi in industrial hydraulic, pneumatic, and instrumentation applications.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician familiar with NPTF thread assembly procedures. Depressurize and isolate the system completely before disassembling any fittings or pipe connections. NPTF threads are designed to seal on the thread form itself; apply thread sealant or PTFE tape only as required by the system manufacturer or applicable codes. Do not overtighten, as this can crack the fitting body or distort the thread seal.
