Parker PPB6FC4-MG Push-to-connect Fitting 3/8x1/4 in

Product Description

The PARKER PPB6FC4-MG is a push-to-connect tube fitting connector designed for quick, tool-free tubing connections in fluid handling and pneumatic systems. Built from polypropylene, this reducer connector joins two different tube outside diameters — 3/8 inch and 1/4 inch — in a single inline fitting. It is rated to 150 psi, making it suitable for low-to-moderate pressure plumbing, HVAC ancillary lines, chemical distribution, and water treatment applications. Plumbers, HVAC technicians, and industrial maintenance professionals install this fitting where a fast, reliable push-in connection is required without threading or soldering.

This fitting is used in residential and light commercial applications involving polyethylene, nylon, or similar semi-rigid tubing. Common install scenarios include RO water systems, ice maker supply lines, pneumatic control tubing, and fluid distribution manifolds. Its reducer configuration handles transitions between 3/8 inch OD and 1/4 inch OD tubing runs in a compact inline footprint. The polypropylene body resists many common chemicals, making it a practical choice for water-based and mild chemical service environments.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Reduces between 3/8 inch OD and 1/4 inch OD tubing in a single fitting
• Polypropylene construction provides corrosion resistance and chemical compatibility for water-based service
• Rated to 150 psi for low-to-moderate pressure systems
• Compact body at approximately 1.41 x 0.81 x 1.41 inches fits tight installation spaces

Compatibility

Designed as an OEM-style push-to-connect replacement connector for systems using 3/8 inch OD and 1/4 inch OD semi-rigid tubing in low-to-moderate pressure fluid or pneumatic service.

Installation Notes

Installation is performed by plumbers or HVAC technicians following applicable plumbing codes such as the IPC. Before servicing, shut off the fluid or air supply and depressurize the line completely. Ensure tubing ends are cut cleanly and squarely with a tube cutter — ragged or angled cuts compromise the push-in seal. Do not exceed the 150 psi pressure rating or use this fitting with tubing types not rated for push-to-connect fittings.
