Parker PPB4MC6-MG Push-to-connect Connector 1/4x3/8 Od

Product Description

The PARKER PPB4MC6-MG is a push-to-connect tube fitting connector designed for quick, tool-free joining of tubing with outside diameters of 1/4 inch and 3/8 inch. Constructed from polypropylene, it is rated for service up to 230 psi and offers corrosion resistance suited to water, chemical, and pneumatic fluid handling applications. The push-to-connect design allows a technician to make a secure, leak-resistant connection simply by inserting the tube into the fitting body — no solvents, clamps, or compression hardware required. This fitting is typically installed by plumbers, HVAC technicians, and industrial maintenance professionals working on fluid or air distribution systems.

This connector is appropriate for residential and light commercial applications where polypropylene fittings are specified, including water supply, pneumatic control lines, and chemical-compatible fluid circuits. The 1/4 inch by 3/8 inch OD configuration makes it a practical choice for reducing or transitioning between two tubing sizes in a single inline connection. It ships individually and is suited for both service repairs and new installations requiring a compact, inline tube connector.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure retention
• Polypropylene construction provides corrosion resistance for water and chemical service
• Rated to 230 psi for use in pneumatic and fluid handling systems
• Connects 1/4 inch OD tubing to 3/8 inch OD tubing in a single inline fitting
• Compact profile at 1.18 inches length and 0.69 inches width for tight installation spaces

Compatibility

Designed as an OEM-style push-to-connect replacement connector for systems using 1/4 inch and 3/8 inch OD polypropylene or compatible tubing in pneumatic or fluid distribution lines.

Installation Notes

Installation is performed by plumbers or HVAC technicians. Before servicing, depressurize the line completely and verify zero pressure at the fitting location. Ensure tubing ends are cut square and deburred before insertion to achieve a proper seal. Follow applicable codes such as the IPC or IFGC for the specific fluid or gas service involved.
