Parker A6MES4-MG Male Swivel Elbow 3/8in Od 1/4in Nptf

Product Description

The PARKER A6MES4-MG is a push-to-connect male swivel elbow tube fitting designed for tube-to-pipe connections in fluid and pneumatic systems. It accepts 3/8-inch OD tubing and connects to a 1/4-inch NPTF male thread. The swivel feature allows the fitting to rotate during installation, simplifying alignment without requiring the tube or mating pipe to move. Constructed from POM (polyoxymethylene), this fitting is rated to 300 psi and suited for systems where a lightweight, corrosion-resistant polymer fitting is appropriate. It is installed by HVAC technicians, plumbers, and fluid-system mechanics in both light commercial and residential applications.

This fitting is used in pneumatic lines, refrigeration ancillary circuits, water distribution, and instrument tubing runs where a 90-degree direction change is needed. The push-to-connect design eliminates the need for ferrules, compression sleeves, or separate fittings, reducing assembly time on tight installations. The gray POM body resists many common chemicals encountered in HVAC and plumbing service environments.

Key Features

• Push-to-connect design accepts 3/8-inch OD tubing without ferrules or extra components
• Swivel elbow body rotates during makeup for easier alignment in tight spaces
• 1/4-inch NPTF male thread provides a pressure-rated pipe connection
• POM (polyoxymethylene) construction offers corrosion resistance and chemical compatibility
• 300 psi pressure rating suitable for pneumatic and fluid service
• Compact gray body at 0.03 pounds for weight-sensitive assemblies

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for systems using 3/8-inch OD tubing with 1/4-inch NPTF male pipe thread connections.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or fluid-system technicians. Depressurize and isolate the system before removing or installing any fitting. Confirm the mating pipe thread is NPTF and apply appropriate thread sealant per the system manufacturer and applicable plumbing or mechanical codes. Seat tubing fully into the push-to-connect collet until it bottoms out, and verify retention by applying a light pull-back on the tube before repressurizing.
