Parker 4 Mtx-s Steel Flared Tube Run Tee 1/4 in Od

Product Description

The PARKER 4 MTX-S is a steel flared tube run tee designed for high-pressure fluid and pneumatic line assemblies. It connects two inline tube runs while providing a branch outlet, making it a standard component in hydraulic, refrigeration, and instrumentation tubing systems. The fitting features a 37-degree flare angle with female-by-male BSPT end connections and a 1/8-27 FNPTF thread standard. Rated to 5000 psi maximum working pressure, this run tee suits demanding service environments. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting in both industrial and commercial mechanical systems.

This fitting is suited for 1/4-inch OD tube applications requiring a tee branch in a continuous run. The 37-degree flare seating angle is a widely used standard in hydraulic and fluid power lines. The female-by-male BSPT end configuration allows integration into existing threaded assemblies. Typical installations include instrument tubing panels, compressed air distribution, hydraulic manifolds, and refrigeration suction or liquid line branching where a steel fitting is required over brass or aluminum alternatives.

Key Features

• Steel construction for durability in high-pressure and high-temperature service
• 37-degree flare angle conforming to standard fluid power fitting geometry
• 1/8-27 FNPTF thread size for reliable thread engagement and leak-free sealing
• Female x Male BSPT end connections for versatile inline installation
• Rated to 5000 psi maximum dynamic working pressure
• Run tee configuration maintains full flow through the main line while supplying a branch port

Compatibility

Designed as an OEM-style replacement or service fitting for 1/4-inch OD flared tube assemblies using 37-degree flare and 1/8-27 FNPTF thread standards in hydraulic, pneumatic, and refrigeration piping systems.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or HVAC technician familiar with flared tube fitting assemblies. Always depressurize and isolate the line completely before removing or installing any fitting. Inspect the flare seat and tube end for burrs or deformation before assembly, as surface defects are a primary cause of leaks at high pressure. Follow applicable codes including ASME B31.3 for process piping or the relevant fluid power standards for the system type.
