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

Product Description

The PARKER 4MBT4N-316 is a stainless steel compression tube male branch tee designed for high-pressure, high-temperature fluid and gas line applications. It features a tee configuration with compression connections on two ports and a male NPT threaded connection on the branch port, allowing a branch line to be added to an existing tube run without welding or flaring. Rated to 10,300 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1,200 degrees F, this fitting is built for demanding service environments. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers of this component.

This fitting is suited for instrumentation, process piping, hydraulic, and pneumatic systems where a reliable branch connection is required in a stainless steel assembly. The compression-to-compression-to-MNPT end configuration makes it adaptable for connecting tubing runs to threaded equipment or manifold ports. It is commonly found in industrial facilities, refineries, chemical plants, and commercial HVAC and refrigeration systems where corrosion resistance and pressure integrity are critical.

Key Features

• Stainless steel construction provides corrosion resistance across a wide range of media and environments
• Maximum working pressure of 10,300 psi supports high-pressure instrumentation and process applications
• Wide temperature range of -425 degrees F to 1,200 degrees F covers cryogenic through high-heat service
• Compression x Compression x MNPT end connections allow tube-to-threaded branch transitions without flaring
• 1/4-18 NPT thread standard ensures compatibility with standard NPT-ported equipment and fittings

Compatibility

Designed as an OEM-style stainless steel compression branch tee for use with standard NPT-threaded systems and compatible compression tube assemblies where a 1/4-18 NPT male branch connection is required.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with compression fitting assembly procedures. Depressurize and isolate the line completely before disassembly or installation. Compression fittings require proper tube preparation including squarely cut, deburred tubing ends to achieve a leak-free seal. Consult applicable codes such as ASME B31.3 for process piping or ASME B31.1 for power piping when specifying fitting torque and assembly procedures.
