Parker 1/8 Mms-s Male Branch Tee 1/8 in Mnptf Fnptf 5000 Psi

Product Description

The PARKER 1/8 MMS-S is a male branch tee fitting designed for high-pressure industrial pipe systems. It connects one male NPTF thread to a female NPTF thread in a tee configuration, allowing a branch line to be added to an existing pipeline run. Constructed from zinc-plated steel, it carries a maximum working pressure of 5,000 psi, making it suitable for demanding hydraulic and pneumatic applications. Both the male and female thread sizes are 1/8 inch NPTF, conforming to SAE standard 140425. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install this fitting in fluid power and compressed-gas distribution systems.

This fitting is used in residential, commercial, and industrial piping installations where a branch connection is needed at a 1/8 inch NPTF port. Typical scenarios include hydraulic manifold assemblies, compressed-air distribution lines, and instrumentation tubing networks where a tee junction is required without disrupting the main line flow path. The MNPTF x FNPTF connection type ensures a pressure-tight, dryseal thread engagement suitable for fluid and gas service at elevated pressures.

Key Features

• Maximum working pressure of 5,000 psi for high-demand hydraulic and pneumatic service
• Zinc-plated steel construction provides corrosion resistance in industrial environments
• 1/8 inch NPTF dryseal threads on both male and female ports for leak-resistant connections
• MNPTF x FNPTF connection type enables branch line addition without additional adapters
• Conforms to SAE standard 140425 for consistent thread form and pressure performance

Compatibility

Designed as an OEM-style replacement or direct-install fitting for industrial pipe systems using 1/8 inch NPTF threaded ports in hydraulic, pneumatic, or fluid instrumentation applications.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or industrial maintenance technician familiar with NPTF dryseal thread fittings. Depressurize and isolate the system completely before removing any existing fittings or installing this tee. NPTF dryseal threads are designed to seal on the threads themselves without pipe sealant, but a compatible thread sealant compound may be applied per system requirements and applicable codes. Do not overtighten, as this can damage the dryseal thread form and compromise the pressure rating.
