Parker 4MSEL2N-B Compression Male Elbow 1/8 in Mnpt

Product Description

The PARKER 4MSEL2N-B is a brass compression tube male elbow fitting designed to connect tubing to male NPT-threaded ports at a 90-degree angle. It features compression-style tube entry on one end and a 1/8 inch MNPT threaded connection on the other, allowing a secure, leak-resistant joint without soldering or brazing. Rated to a maximum working pressure of 3500 psi, this fitting is built for high-pressure fluid and instrumentation systems. Plumbers, HVAC technicians, and instrumentation mechanics routinely specify brass compression fittings like this for reliable, field-serviceable connections in both pneumatic and hydraulic lines.

This fitting is suited for residential and commercial plumbing, HVAC refrigerant and instrument tubing lines, and industrial fluid control applications where a compact 90-degree directional change is needed. The compression x MNPT configuration makes it a common choice when connecting copper or compatible soft tubing to threaded equipment ports, valve bodies, gauges, or manifolds. It is sold individually and is appropriate for new construction as well as retrofit and repair work.

Key Features

• Compression x MNPT end connections allow tool-assisted, solder-free tube-to-thread joints
• Rated to 3500 psi maximum working pressure for demanding fluid and instrumentation service
• Brass construction provides corrosion resistance and compatibility with a wide range of media
• 1/8 inch thread size fits standard NPT-threaded ports on gauges, valves, and equipment fittings
• 90-degree elbow geometry for directional routing in tight installation spaces
• Single-piece package quantity, orderable in individual quantities with no minimum order requirement beyond one unit

Compatibility

Designed as an OEM-style compression tube male elbow for use in high-pressure fluid, pneumatic, and instrumentation plumbing systems requiring a 1/8 inch MNPT threaded port connection.

Installation Notes

This fitting should be installed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic. De-pressurize and isolate the line before disassembly or installation. Compression fittings require proper tube squareness and seating of the ferrule against the fitting body; do not over-tighten, as this can deform the ferrule and compromise the seal. Follow applicable plumbing and mechanical codes, including IPC and ASME B16.39 guidelines where required, for threaded and compression joint installations.
