Parker 12MBT12N-316 Compression Male Branch Tee 3/4-14

Product Description

The PARKER 12MBT12N-316 is a stainless steel compression tube male branch tee designed for high-pressure instrumentation and fluid system applications. It provides a three-port branch connection with two compression ends and one male NPT end, allowing a branch takeoff from a compression tube run while threading directly into a port or manifold. Rated to 5800 psi maximum working pressure and capable of operating across an extreme temperature range, this fitting is built for demanding process, pneumatic, and hydraulic service. Licensed plumbers, pipefitters, and instrumentation technicians install this type of fitting in industrial and commercial systems where reliable leak-free connections are required.

This fitting is suited for stainless steel tubing systems in process piping, instrumentation lines, HVAC hydronic applications, and similar environments where corrosion resistance and high-pressure integrity are critical. The 3/4-14 NPT male thread connects to standard female NPT ports on valves, manifolds, or equipment. The compression connections on the remaining two ports accept compatible OD tubing, making it a practical branch point without the need for welded or soldered joints.

Key Features

• 316 stainless steel construction for corrosion resistance in aggressive media and outdoor environments
• Maximum working pressure of 5800 psi for high-pressure instrumentation and process service
• Wide temperature range from -425 degrees F to 1200 degrees F supports cryogenic through high-heat applications
• 3/4-14 NPT male thread conforms to standard NPT thread specification for broad port compatibility
• Compression x Compression x MNPT end configuration allows inline branch takeoff with direct port connection
• Overall length of 3.14 inches suits space-constrained panel and manifold installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for stainless steel compression tube systems using 3/4-14 NPT threaded ports and compatible compression tube OD sizes.

Installation Notes

Installation should be performed by a qualified pipefitter or instrumentation technician following applicable codes such as the IPC and ASME B31.3 for process piping. Depressurize and isolate the system completely before removing or installing any compression fitting. Use a calibrated torque wrench and follow the ferrule make-up procedure specified for the tube OD to ensure a leak-free compression seal. Do not overtighten NPT threads; apply an appropriate thread sealant compatible with the system media and temperature range.
