Parker 4MSEL4N-316 Compression Male Elbow Ss

Product Description

The PARKER 4MSEL4N-316 is a stainless steel compression tube male elbow fitting designed to connect 1/4-inch OD tubing to a 1/4-18 NPT male threaded port at a 90-degree angle. Built from 316-grade stainless steel, it handles working pressures up to 10300 psi and temperatures ranging from 0 degrees F to 1200 degrees F. This fitting is sized and rated for demanding fluid and gas distribution applications where corrosion resistance and pressure integrity are critical. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This fitting is used in high-pressure instrumentation lines, pneumatic systems, hydraulic circuits, and process piping where a 90-degree direction change is needed between a compression tube connection and an NPT threaded port. Its stainless steel construction makes it well suited for corrosive environments, high-temperature service, and applications where cleanliness and material compatibility are required. Typical installations include industrial process controls, HVAC hydronic systems, and compressed gas distribution lines.

Key Features

• 316 stainless steel construction for corrosion resistance in aggressive service environments
• Maximum working pressure of 10300 psi for high-pressure applications
• Wide temperature range: 0 degrees F to 1200 degrees F
• 1/4-inch OD tube compression inlet with 1/4-18 NPT male outlet
• 90-degree elbow geometry for direction changes in tight installations
• Compression-style connection requires no solder, flare, or brazing

Compatibility

Designed as an OEM-style replacement or direct-fit compression elbow for 1/4-inch OD tubing systems using 1/4-18 NPT threaded ports in instrumentation, pneumatic, and process piping applications.

Installation Notes

This fitting is typically installed by licensed pipefitters, plumbers, or instrumentation technicians. Shut off system pressure and depressurize all lines completely before removing or installing any compression fitting. Hand-tighten the compression nut onto the NPT port, then tighten to the ferrule-engagement point per standard compression fitting practice — do not overtighten. Verify local codes, including applicable sections of the IPC or ASME B31.3, for pressure piping requirements in your jurisdiction.
