Parker 8MSEL4N-316 Compression Male Elbow 1/4-18 Npt Ss

Product Description

The PARKER 8MSEL4N-316 is a stainless steel compression tube male elbow fitting designed to connect compression tubing to a male NPT threaded port in a 90-degree configuration. With a 1/4-18 NPT thread size and an end connection pairing of compression by MNPT, this fitting is built for high-pressure fluid and gas line applications where leak-free performance is required. The 316 stainless steel construction offers strong resistance to corrosion, making it suitable for demanding service environments. It carries a maximum working pressure rating of 6300 psi. Licensed plumbers, pipefitters, and instrumentation technicians typically install this type of compression elbow in process, HVAC, and industrial piping systems.

This fitting is used in residential, commercial, and light industrial applications where a direction change from a compression tube run to a male NPT threaded connection point is needed. Common install scenarios include instrument tubing lines, refrigeration and gas service piping, and hydraulic or pneumatic control circuits. The compression end accepts standard tubing and creates a reliable seal without soldering or welding, which makes it practical for field installations and retrofits.

Key Features

• 316 stainless steel construction for corrosion resistance in wet or chemically active environments
• Maximum working pressure of 6300 psi for high-pressure line service
• 1/4-18 NPT thread standard ensures compatibility with standard threaded pipe ports
• Compression by MNPT end connections allow tube-to-pipe transitions without soldering or welding
• 90-degree elbow configuration for direction changes in tight or confined plumbing layouts
• Sold individually, suitable for single-unit replacement or repair work

Compatibility

Designed as an OEM-style replacement or direct-use compression fitting for standard NPT-threaded ports in instrumentation, HVAC, and industrial fluid or gas piping systems requiring a 1/4-18 NPT compression male elbow connection.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or instrumentation technician in accordance with applicable codes including ASME B31.1 or B31.3 for pressure piping. Depressurize and isolate the line completely before removing any existing fitting or installing this elbow. Apply thread sealant appropriate for the service medium to the NPT threads before making up the connection; hand-tighten first, then wrench-tighten to achieve a proper seal without over-stressing the fitting body. Ensure the compression end is seated correctly on clean, undamaged tubing before applying final compression.
