Parker A4MC2-MG Push-to-connect Connector 1/4in Od 1/8in Nptf

Product Description

The PARKER A4MC2-MG is a push-to-connect tube-to-pipe connector fitting designed for quick, tool-free tube connections in pneumatic and fluid distribution systems. Constructed from polyoxymethylene (POM), this fitting accepts 1/4 inch OD tubing and connects to a 1/8 inch NPTF female thread port. It is rated to 300 psi, making it suitable for moderate-pressure pneumatic lines. The tan-colored POM body resists many common industrial fluids and provides a lightweight, low-profile alternative to brass fittings. HVAC technicians, plumbers, and industrial service technicians use this style of fitting when routing control tubing, sensor lines, or low-pressure fluid lines where fast assembly and reliable sealing are required.

This connector is used in residential and light commercial applications wherever 1/4 inch OD tubing meets a 1/8 inch NPTF threaded port. Common install scenarios include pneumatic control panels, condensate management systems, pressure sensing lines, and instrumentation tubing runs. The push-to-connect design eliminates the need for ferrules, compression sleeves, or special tooling at the tube end, reducing assembly time in tight spaces or high-count installations.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure retention
• 1/4 inch OD tube connection with 1/8 inch NPTF male pipe thread
• Rated to 300 psi for use in moderate-pressure pneumatic and fluid lines
• Polyoxymethylene (POM) body offers good chemical resistance and a lightweight build
• Tan color allows quick visual identification of fitting material in multi-fluid systems
• Compact connector profile suited to tight panel and cabinet installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4 inch OD tubing with 1/8 inch NPTF threaded ports in pneumatic and low-pressure fluid distribution applications.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or instrumentation technicians. Before connecting or disconnecting, depressurize the line completely and verify the system is de-energized if the tubing serves a pneumatic control circuit. Ensure the NPTF threads are clean and apply thread sealant appropriate for the service fluid before threading the fitting into the port. To insert tubing, push the tube firmly into the fitting until it seats; to release, depress the collet ring and withdraw the tube.
