The ANDERSON METALS CORP 710066-0504 is a compression-to-female iron pipe (FIP) adapter designed to transition a 5/16 inch compression fitting connection to a 1/4 inch female iron pipe thread. This fitting creates a reliable, leak-resistant joint between soft copper or plastic tubing and a standard FIP-threaded port. It is lead free compliant and meets the requirements of Public Law 111-380, making it suitable for potable water applications. Plumbers and pipefitters install this adapter in residential and light commercial plumbing systems where tubing must terminate at a threaded fitting or valve body.
This adapter is commonly used in water supply lines, refrigerator ice maker connections, reverse osmosis systems, and other small-diameter tubing installations where a compression-to-pipe-thread transition is required. It is sold in a package of 10 and arrives carded for easy jobsite inventory. The 5/16 inch compression side accepts standard compression sleeves and nuts, while the 1/4 inch FIP end threads directly onto male iron pipe thread fittings.
Designed as an OEM-style replacement or new-installation fitting for residential and light commercial plumbing systems using 5/16 inch compression tubing terminating at 1/4 inch male iron pipe thread ports.
This fitting is installed by licensed plumbers or qualified pipefitters. Shut off the water supply and relieve line pressure before making any connections. Ensure the compression sleeve and nut are properly seated on the tubing before tightening the compression end; do not overtighten, as this can deform the sleeve and cause leaks. Thread the FIP end onto the mating male pipe thread fitting using appropriate thread sealant tape per local plumbing code requirements.
