Parker A5ME4-MG Push-to-connect Male Elbow 5/16 Od 1/4 Nptf

Product Description

The PARKER A5ME4-MG is a push-to-connect male elbow tube fitting designed for tube-to-pipe connections in pneumatic and fluid transfer systems. It accepts 5/16 inch OD tubing and connects to a 1/4 inch NPTF threaded port. The body is molded from POM (polyoxymethylene), a rigid acetal resin that resists moisture, fuels, and mild chemicals. Rated to 300 psi, this fitting handles the working pressures common in compressed air, light hydraulic, and instrumentation lines. The push-to-connect mechanism allows fast, tool-free tube insertion while the 90-degree elbow orientation simplifies routing in tight spaces. Installers in HVAC, refrigeration, pneumatic controls, and industrial plumbing specify this style when a directional change is needed at a threaded port.

This fitting is suited for residential and light commercial applications involving PTC pneumatic or fluid lines. Common install scenarios include instrument air tubing, condensate management systems, pneumatic control panels, and small-bore process lines where a 90-degree male-threaded transition is required. The tan POM body is compatible with a range of tubing materials including nylon and polyurethane. It is sold individually and is appropriate wherever a compact, low-weight elbow fitting is needed at a 1/4 inch NPTF port.

Key Features

• Push-to-connect design allows tool-free tube insertion and release
• 90-degree elbow orientation routes tubing away from threaded port face
• POM (polyoxymethylene) body resists moisture, fuels, and mild chemicals
• 300 psi pressure rating suitable for compressed air and instrumentation lines
• 1/4 inch NPTF male thread provides a dry, pressure-tight pipe connection
• Accepts 5/16 inch OD tubing — compatible with common nylon and polyurethane line

Compatibility

Designed as an OEM-style push-to-connect replacement or new-installation fitting for systems using 5/16 inch OD tubing terminated at a 1/4 inch NPTF threaded port.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or instrumentation technicians depending on the application. Depressurize and isolate the line before removing or installing any fitting. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect collet — a burred or angled cut can compromise the internal seal. Apply appropriate thread sealant to the NPTF male threads per the system fluid and local code requirements before torquing into the mating port.
