The PARKER PPB4FA7-MG is a push-to-connect faucet adapter tube fitting designed to create a quick, tool-free connection between a 1/4 inch OD tube and a 7/16-24 UNS threaded port. Constructed from black polypropylene, this fitting is rated to 230 psi and provides a reliable seal for low-pressure fluid lines. The push-to-connect design allows tubing to be inserted and locked without ferrules, nuts, or additional fittings. Plumbers, water treatment technicians, and HVAC service pros install this fitting where a threaded faucet port needs to transition to small-diameter tubing quickly and cleanly.
This faucet adapter is suited for residential and light commercial applications including water filtration systems, reverse osmosis installations, ice maker supply lines, and similar low-pressure potable or process water plumbing. It is a compact, single-piece fitting intended for installations where space is limited and repeated connection and disconnection may be required.
Designed as an OEM-style push-to-connect replacement adapter for plumbing and fluid handling systems using 1/4 inch OD tubing and 7/16-24 UNS threaded faucet ports, such as those commonly found in water filtration and reverse osmosis systems.
This fitting is installed by licensed plumbers or qualified water treatment technicians. Shut off the water supply and relieve line pressure before removing or installing any fitting. Ensure tubing is cut cleanly and squarely and inserted fully until it bottoms out in the fitting body to achieve a proper seal. To release tubing, depress the collet ring while pulling the tube free.
