Parker 12MSEL8N-B Compression Male Elbow 1/2 in Brass

Product Description

The PARKER 12MSEL8N-B is a brass compression tube male elbow fitting designed to transition between a compression tube connection and a male NPT threaded port. The fitting features a 1/2 inch thread size with a Compression x MNPT end connection configuration, allowing techs to connect tubing to threaded pipe or equipment ports at a 90-degree angle. Rated to a maximum working pressure of 1900 psi, this elbow is built for demanding fluid and gas line applications where a reliable, leak-resistant mechanical connection is required. Plumbers, HVAC technicians, and industrial pipefitters commonly install this type of fitting in both new construction and retrofit work.

This male elbow fitting is suited for use in residential and light commercial plumbing systems, HVAC refrigerant or fluid lines, pneumatic systems, and instrumentation tubing runs where a directional change from tubing to a threaded port is needed. The compression end accepts standard tubing without soldering or flaring, while the MNPT end threads directly into female pipe ports on valves, manifolds, or equipment housings. Its brass construction makes it compatible with a wide range of media including water, air, and many hydraulic fluids.

Key Features

• 1/2 inch thread size with Compression x MNPT end connections for tool-free tubing attachment
• Maximum working pressure rated to 1900 psi for high-demand service environments
• Brass construction provides corrosion resistance and durability across a broad range of media
• 90-degree male elbow geometry allows directional routing in tight or confined installations
• MPT thread standard ensures compatibility with standard female pipe thread ports

Compatibility

Designed as an OEM-style compression fitting for use in plumbing, HVAC, pneumatic, and instrumentation systems requiring a 1/2 inch Compression x MNPT male elbow connection in brass. Cross-reference Swagelok part number B-1210-2-8 for equivalent specification sourcing.

Installation Notes

This fitting is typically installed by licensed plumbers or HVAC technicians. Always depressurize and isolate the line before removing or installing any compression fitting. Hand-tighten the compression nut onto the tubing, then advance with a wrench per standard compression fitting practice — do not overtighten, as brass fittings are susceptible to thread and ferrule damage. Ensure the tubing end is cut squarely and is free of burrs before seating in the compression end.
