Parker 8MBT6N-316 Compression Male Branch Tee 3/8-18

Product Description

The PARKER 8MBT6N-316 is a stainless steel compression tube male branch tee designed for high-pressure fluid and gas distribution systems. It connects two compression tube runs while providing a male NPT branch outlet, allowing a single inline tap without cutting into a main line. Rated to 6300 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1200 degrees F, this fitting is built for demanding industrial, instrumentation, and HVAC-adjacent applications. It is typically installed by licensed pipefitters, plumbers, or instrumentation technicians working with tubing systems that require a reliable, corrosion-resistant branch connection.

This fitting is suited for use in industrial process lines, high-pressure instrumentation tubing, pneumatic control systems, and corrosive-media applications where stainless steel is required. The 3/8-18 NPT male thread on the branch outlet mates to standard female NPT ports on valves, instruments, or manifolds. The compression ends accept standard tubing on both inline ports, making it a versatile branch fitting across residential and commercial mechanical systems wherever corrosion resistance and high-pressure rated connections are needed.

Key Features

• Stainless steel construction for corrosion resistance in wet, chemical, and high-temperature environments
• Rated to 6300 psi maximum working pressure for high-pressure instrumentation and process lines
• Wide temperature range from -425 degrees F to 1200 degrees F covers cryogenic through high-heat applications
• 3/8-18 NPT male branch outlet mates to standard female NPT fittings and ports
• Compression x Compression x MNPT end configuration allows inline branch without welding or flanging

Compatibility

Designed as an OEM-style replacement or new-installation compression branch tee for stainless steel tubing systems using 3/8-18 NPT thread connections in high-pressure instrumentation and process piping applications.

Installation Notes

Installation should be performed by a qualified pipefitter or licensed plumber familiar with compression fittings and NPT thread assembly. Depressurize and isolate the line completely before disassembling any existing connections or installing this fitting. Apply an appropriate thread sealant to the male NPT branch threads per the system fluid and applicable piping codes such as ASME B31.3 or IFGC. Do not overtighten compression nuts, as stainless steel ferrules require controlled hand-plus-turns torque to seat properly without cracking.
