Parker A4ME6-MG Male Elbow Tube Fitting 1/4 in Od 3/8 in Nptf

Product Description

The PARKER A4ME6-MG is a push-to-connect male elbow tube fitting designed to connect 1/4 inch OD tubing to a 3/8 inch NPTF male threaded port. The elbow configuration redirects flow 90 degrees without additional fittings or tools. Constructed from acetal (polyoxymethylene), this fitting handles a maximum working pressure of 300 psi and is rated for temperatures from -20 degrees F to 180 degrees F. It is used across HVAC, pneumatic, and fluid handling systems where a fast, reliable tube-to-pipe connection is required. Installation requires no ferrules or compression sleeves — tubing seats and locks by insertion alone.

This fitting is suited for light industrial and commercial applications involving air, water, and compatible fluid lines. Typical install scenarios include instrumentation tubing runs, pneumatic control circuits, and low-pressure fluid distribution lines found in HVAC equipment, refrigeration ancillaries, and plumbing control systems. The tan acetal body resists corrosion and is compatible with a range of non-aggressive media. Technicians working with 1/4 inch OD poly or nylon tubing routed to 3/8 inch NPT ports will find this a direct-fit solution.

Key Features

• Push-to-connect design — no tools required for tube insertion
• 90-degree male elbow routes tubing without additional elbows or adapters
• Acetal (polyoxymethylene) body resists corrosion and chemical degradation
• Rated to 300 psi maximum working pressure
• Operating temperature range: -20 degrees F to 180 degrees F
• 3/8 inch NPTF thread for a pressure-tight pipe connection

Compatibility

Designed for use with 1/4 inch OD tubing and 3/8 inch NPTF threaded ports in pneumatic, HVAC, and fluid handling systems. Verify tubing material and media compatibility with acetal before installation.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or instrumentation specialists. Ensure the system is fully depressurized and drained before removing or installing any fittings. Thread the male NPTF end into the mating port with appropriate thread sealant per the fitting manufacturer and applicable plumbing code requirements. Insert tubing straight into the push-to-connect end until it seats fully; to release, depress the collet ring and pull the tubing straight out.
