Parker 6MSEL4N-316 Compression Male Elbow 1/4-18 Mnpt Ss

Product Description

The PARKER 6MSEL4N-316 is a stainless steel compression tube male elbow fitting designed to connect tubing to a male NPT threaded port at a 90-degree angle. Built from 316 stainless steel, this fitting handles extreme temperature ranges from -425 degrees F to 1200 degrees F and a maximum working pressure of 6600 psi, making it suitable for demanding industrial, instrumentation, and process-control applications. The compression end provides a secure, leak-resistant tube connection without welding or soldering. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.

This fitting is used in high-pressure fluid and gas line assemblies where a directional change from tubing to a threaded male port is required. Common applications include hydraulic systems, pneumatic instrumentation lines, chemical processing, and refrigeration or cryogenic systems where wide temperature swings and elevated pressures are present. The 1/4-18 NPT thread size is a standard trade size used across a broad range of industrial valves, manifolds, and equipment ports.

Key Features

• 316 stainless steel construction provides excellent corrosion resistance in harsh and corrosive environments
• Maximum working pressure of 6600 psi for high-pressure system use
• Rated for temperatures from -425 degrees F to 1200 degrees F, including cryogenic service
• Compression x MNPT end connections allow tubing to threaded port transitions without welding
• 1/4-18 NPT thread conforms to standard NPT thread specification
• Single-piece construction with no loose components to lose during installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube to male NPT threaded connections in industrial, instrumentation, and process-control piping systems requiring 1/4-18 NPT thread size.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with compression fittings and NPT thread sealing practices. Shut off and depressurize the system completely before disassembly or installation. Apply an appropriate thread sealant to the male NPT threads per the system fluid compatibility requirements. Do not overtighten compression fittings; follow the fitting manufacturer's recommended hand-tight plus turns procedure to avoid deforming the ferrule.
