Parker PP4FA7 Push-to-connect Faucet Adapter 1/4 in Od

Product Description

The PARKER PP4FA7 is a push-to-connect faucet adapter fitting designed to create a fast, tool-free connection between a 1/4-inch OD tube and a 7/16-24 UNS-2B threaded faucet port. Constructed from polypropylene in a tan color, this fitting is rated to 150 psi and is suited for low-pressure water supply lines in filtration, drinking water, and point-of-use applications. The push-to-connect design allows the tube to seat and seal by simply inserting it into the fitting body, reducing installation time. Plumbers and water treatment technicians are the primary installers of this type of fitting.

This fitting is used in residential and light commercial water filtration systems, reverse osmosis installations, and under-sink drinking water setups where a faucet port connection to 1/4-inch tubing is required. It is appropriate for cold water lines in environments where polypropylene construction provides adequate chemical and temperature compatibility. The compact profile fits into tight cabinet or under-sink spaces without the need for additional tools.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion for 1/4-inch OD tubing

Compatibility

Designed as an OEM-style push-to-connect adapter for faucet ports accepting a 7/16-24 UNS-2B thread and 1/4-inch OD tubing, typical of residential reverse osmosis and drinking water filtration faucets.

Installation Notes

Installation is performed by a plumber or water treatment technician. Shut off the water supply and relieve line pressure before connecting or disconnecting any fitting. Ensure the tube end is cut cleanly and squarely with a tube cutter for a proper push-to-connect seal. Do not exceed the 150 psi pressure rating or use this polypropylene fitting on hot water lines without verifying temperature compatibility.
