Eastman K2037LF 3/8" x 1/4" Lead-Free Compression Adapter

The Eastman K2037LF is a 3/8" x 1/4" compression adapter built for behind-the-wall and under-fixture rough-in work where a supply line needs to transition between two compression tube sizes. This lead-free adapter is designed for plumbers and contractors making up water supply connections at stops, valves, and fixture tailpieces, and it provides a straightforward compression-to-compression joint without soldering or solvent welding. As a lead-free (LF) fitting, the K2037LF is intended for potable water supply applications where lead-free construction is required.
