Parker A4MES4-MG Male Swivel Elbow 1/4 in Od Nptf

Product Description

The PARKER A4MES4-MG is a push-to-connect male swivel elbow tube fitting designed for tube-to-pipe connections in fluid and pneumatic systems. Manufactured from POM (polyoxymethylene), this fitting accepts 1/4 inch OD tubing and connects to a 1/4 inch NPTF male thread. The push-to-connect end allows fast, tool-free tube insertion while the swivel elbow design permits rotation during installation to align the fitting without twisting the tubing or the pipe connection. Rated to 300 psi, this fitting is suited for compressed air, water, and compatible fluid service lines where a compact 90-degree directional change is required.

This fitting is used in residential and light commercial applications wherever a tube-to-threaded-pipe transition at a right angle is needed. Typical install scenarios include pneumatic control lines, instrumentation tubing runs, HVAC equipment ancillary connections, and general fluid distribution panels. The NPTF thread provides a pressure-tight seal without relying solely on thread sealant, making it a practical choice for field installations where consistent sealing is a priority.

Key Features

Compatibility

Designed as an OEM-style push-to-connect fitting for use with 1/4 inch OD tubing and 1/4 inch NPTF threaded pipe ports in pneumatic, instrumentation, and fluid distribution systems.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or instrumentation mechanics. Shut off system pressure and depressurize the line completely before removing or installing any fitting. Ensure tubing is cut square and deburred before inserting into the push-to-connect end to achieve a reliable seal. Apply an appropriate thread sealant to the NPTF threads per manufacturer and applicable code guidance before making up the pipe connection.
