Parker 6MBT4N-316 Compression Male Branch Tee 1/4-18 Npt Ss

Product Description

The PARKER 6MBT4N-316 is a stainless steel compression tube male branch tee designed for high-pressure and extreme-temperature fluid and gas line applications. It connects two compression tube ends to a male NPT branch port, making it suited for instrumentation, process, and HVAC refrigerant or pneumatic control tubing runs. The fitting handles up to 6,600 psi working pressure and a temperature range from -425 degrees F to 1,200 degrees F, making it appropriate for cryogenic through high-heat service. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers. The 316 stainless construction resists corrosion in aggressive media and damp environments.

This male branch tee fits into high-pressure tubing systems where a single inline fitting must serve both a straight-through tube run and a perpendicular male NPT branch connection. Common applications include compressed air, refrigerant control lines, hydraulic instrumentation, and industrial process piping where stainless steel is required for corrosion resistance or temperature compatibility. The 1/4-18 NPT thread size is standard for small-bore instrumentation and control line work in both commercial and industrial settings.

Key Features

• Maximum working pressure of 6,600 psi for high-pressure service
• Wide temperature range: -425 degrees F to 1,200 degrees F, suitable for cryogenic and high-heat applications
• 316 stainless steel construction for corrosion resistance in aggressive environments
• Compression x Compression x MNPT end connections for versatile tubing and pipe integration
• 1/4-18 NPT thread standard for compatibility with common small-bore instrumentation fittings

Compatibility

Designed as an OEM-style replacement or direct-install fitting for high-pressure compression tube systems using 1/4-18 NPT male branch connections in stainless steel instrumentation and process piping.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with high-pressure compression fittings. Depressurize and isolate the line fully before disassembly or fitting installation. Follow applicable codes including ASME B31.1 or B31.3 for pressure piping systems. Do not overtighten compression ferrules; follow the fitting manufacturer's turn-count torque method rather than relying on thread feel alone.
