Parker A6TMC6 Tube Stem Adapter 3/8 in Od 3/8 in Nptf 300 Psi

Product Description

The PARKER A6TMC6 is a push-to-connect tube stem adapter designed for quick, tool-free tube connections in pneumatic and fluid-handling systems. Built from polyoxymethylene (POM), this fitting accepts 3/8-inch outside-diameter tubing and threads into a 3/8-inch NPTF port, rated to 300 psi working pressure. The tan-colored POM body resists moisture and many common hydraulic and pneumatic fluids, making it suitable for light industrial, HVAC controls, and plumbing instrument lines. Installation requires no ferrules, sleeves, or compression tools — the push-to-connect design locks tubing with a single insertion. Licensed plumbers, HVAC technicians, and industrial maintenance technicians are the typical installers.

This adapter is appropriate for use in residential and light commercial applications where push-to-connect fittings are used to transition between tubing runs and threaded port connections. It is well suited for instrument air lines, control tubing, pneumatic actuator circuits, and low-pressure fluid-transfer setups. The NPTF thread type provides a pressure-tight dry-seal connection without relying solely on thread sealant. Typical installs involve connecting flexible poly or nylon tubing to valve bodies, manifolds, or equipment panels with threaded ports.

Key Features

• Push-to-connect design allows fast, tool-free tubing insertion
• 3/8-inch OD tubing acceptance with 3/8-inch NPTF male thread
• 300 psi working pressure rating
• Polyoxymethylene (POM) body resists moisture and common process fluids
• NPTF dry-seal thread eliminates need for thread-sealant tape in many applications
• Compact and lightweight at 0.05 pounds per piece

Compatibility

Designed for use with 3/8-inch outside-diameter tubing in systems equipped with 3/8-inch NPTF threaded ports. Verify thread type and tubing OD before installation.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified industrial maintenance personnel. Depressurize and isolate the line completely before removing any existing fitting or inserting this adapter. Confirm the mating port is NPTF — do not force an NPTF fitting into NPT or BSPT ports without verifying thread compatibility. To release tubing from the push-to-connect collet, depress the release ring while pulling the tubing straight out.
