The PARKER FB4FA7-HBLK is a push-to-connect faucet adapter tube fitting designed for quick, tool-free connections in low-pressure fluid handling systems. Constructed from Kynar (PVDF) with a black finish, this fitting accepts 1/4-inch outside diameter tubing and connects to a 7/16-inch UNS thread port. The FKM o-ring provides reliable sealing compatibility with a wide range of fluids. Rated to 250 psi and a vacuum rating of 28 in-Hg, it is suited for water filtration, reverse osmosis, and similar plumbing applications. Plumbers and water treatment technicians are the primary installers of this fitting type.
This fitting is used in residential and light commercial plumbing systems where push-to-connect convenience and chemical-resistant construction are required. Typical applications include under-sink water filtration systems, reverse osmosis installations, ice maker supply lines, and faucet adapter connections. The Kynar body resists chlorine, mild acids, and common potable water treatment chemicals, making it a practical choice for drinking water system service work.
Designed as an OEM-style push-to-connect faucet adapter for plumbing systems using 1/4-inch OD tubing with 7/16-inch UNS threaded ports, typical of residential water filtration and reverse osmosis equipment.
Installation should be performed by a licensed plumber or qualified water treatment technician. Shut off the water supply and relieve line pressure before removing or installing this fitting. Ensure tubing is cut cleanly and squarely, and that the tube end is fully seated before pressurizing the system. Follow all applicable local plumbing codes and manufacturer guidelines for potable water system work.
