Parker 12MSEL12N-B Compression Male Elbow 3/4 in Mnpt

Product Description

The PARKER 12MSEL12N-B is a brass compression tube male elbow fitting designed to create a 90-degree directional change in tubing runs while transitioning from a compression connection to a male NPT threaded port. Constructed from brass, it handles a maximum working pressure of 1900 psi, making it suitable for demanding fluid and gas line applications. The 3/4 inch MNPT thread mates with standard pipe thread ports, and the compression end accepts tubing for a leak-resistant mechanical connection. Plumbers, pipefitters, and HVAC technicians install this fitting in systems where a rigid tube must connect to a threaded male port at an angle.

This fitting is used in residential and commercial plumbing, HVAC refrigerant and fluid lines, pneumatic systems, and industrial process piping where a compression-to-MNPT elbow transition is required. The brass construction suits water, air, and compatible fluid service. It is typically installed in tight spaces or panel installations where a straight fitting would require a separate elbow, saving fittings and reducing potential leak points in the line.

Key Features

• Brass construction for corrosion resistance and durability in fluid and gas service
• 1900 psi maximum working pressure rated for demanding system use
• 3/4 inch MNPT threaded end mates with standard pipe thread ports
• Compression end provides a reliable mechanical tube connection without soldering
• 90-degree elbow configuration allows directional routing in confined installations
• Swagelok cross-reference part number B-1210-2-12 for identification and sourcing

Compatibility

Designed as an OEM-style compression tube male elbow for use in plumbing, HVAC, pneumatic, and industrial fluid systems requiring a compression-to-3/4 inch MNPT connection.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable IPC or system-specific codes. Depressurize and isolate the system completely before removing or installing any fittings. Do not overtighten the compression nut; hand-tighten then advance with a wrench to the fitting manufacturer's standard procedure for compression connections. Inspect the tubing end for squareness and burrs before assembly to ensure a proper seal.
