Parker 12MSEL12N-316 Compression Male Elbow 3/4-14 Npt

Product Description

The PARKER 12MSEL12N-316 is a stainless steel compression tube male elbow designed to connect compression tubing to a male NPT threaded port in a 90-degree configuration. It features a 3/4-14 NPT thread and accepts a compression-style tube end on the opposing connection. Rated to 5800 psi maximum working pressure, it handles extreme temperature ranges from -425 degrees F to 1200 degrees F, making it suitable for high-pressure instrumentation, hydraulic, pneumatic, and process piping applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This fitting is used in industrial, commercial, and high-purity process systems where a direction change from compression tubing to a male NPT port is required. Common applications include instrumentation lines, compressed gas systems, hydraulic circuits, and chemical process piping where stainless steel corrosion resistance is required. The compression end eliminates the need for tube flaring, allowing for a clean, repeatable connection in tight spaces or multi-branch assemblies.

Key Features

• 3/4-14 NPT male thread for direct connection to female NPT ports
• Compression x MNPT end connections for tool-assisted, leak-tight assembly
• Stainless steel construction for corrosion resistance in aggressive media environments
• Maximum working pressure of 5800 psi for high-pressure service
• Wide temperature range: -425 degrees F to 1200 degrees F
• 90-degree elbow geometry for directional routing in confined installations

Compatibility

Designed as an OEM-style compression fitting for use in high-pressure tubing assemblies requiring a male NPT elbow transition. Suitable for systems where stainless steel 316-series fittings are specified.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician following applicable codes such as ASME B31.3 for process piping. Depressurize and isolate the system completely before disassembly or fitting installation. Use appropriate thread sealant rated for the service media on the NPT threads, and tighten the compression nut with a backup wrench on the fitting body to prevent body rotation. Do not overtighten the compression nut, as this can deform the ferrule and compromise the seal.
