Parker 3MBT2N-316 Compression Male Branch Tee 1/8-27

Product Description

The PARKER 3MBT2N-316 is a stainless steel compression tube male branch tee designed for high-pressure, wide-temperature-range fluid and gas line applications. It features a Compression x Compression x MNPT end connection configuration with a 1/8-27 NPT male threaded outlet. Rated to 10,300 psi maximum working pressure and a temperature range of -425 to 1,200 degrees F, this fitting is built for demanding environments where leak-free performance is critical. Installers in HVAC, instrumentation, chemical processing, and industrial plumbing rely on this type of fitting to branch a compressed tube line while maintaining a threaded port connection.

This fitting is suited for both commercial and industrial applications where stainless steel construction is required for corrosion resistance or elevated temperature service. Typical use cases include instrument tubing systems, pneumatic control lines, and process piping where a branch takeoff with an NPT port is needed. The tee configuration allows two compression tube connections to pass through while the male NPT port provides a threaded outlet for gauges, sensors, or additional line connections.

Key Features

• Stainless steel body for corrosion resistance and high-temperature durability
• Compression x Compression x MNPT end connections for versatile installation
• 1/8-27 NPT male thread for compatibility with standard instrumentation ports
• Rated to 10,300 psi maximum working pressure
• Operates across an extreme temperature range of -425 to 1,200 degrees F
• Tee configuration supports branch line takeoffs without additional fittings

Compatibility

Designed as an OEM-style replacement or new-installation compression tee fitting for systems using 1/8-27 NPT threaded connections with compression tube ends in stainless steel service.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or instrumentation technicians. Depressurize and isolate the line completely before disassembly or installation of any compression fitting. Follow applicable codes including ASME B31.1 or B31.3 for pressure piping systems. Do not overtighten compression ferrules, as this can deform the tube end and compromise the seal.
