The BRASS CRAFT SERVICE PARTS R3701RX RD is a dual outlet shutoff valve designed for residential and light commercial plumbing supply lines. It connects a 1/2 inch Female Iron Pipe inlet to two compression outlets: one at 1/2 inch OD and one at 3/8 inch OD. The valve is multi-turn style, providing controlled flow adjustment rather than a single quarter-turn actuation. Constructed from rough brass, it is built for durability in behind-the-wall and under-sink applications. The R3701RX RD is lead free compliant, meeting federal and state potable water standards. Licensed plumbers and experienced service techs install this valve where a single supply line must feed two fixtures or appliances simultaneously.
This dual outlet valve is suited for under-sink installations where a cold water supply line must branch to serve two connections, such as a faucet supply and an ice maker, dishwasher, or filtration system feed. The 1/2 inch FIP inlet threads directly onto standard iron pipe or compatible fittings. The two compression outlets accommodate common supply tube sizes found in residential kitchens and bathrooms. It is packaged individually on a card and sold in a package quantity of 5 units, making it practical for stocking service vehicles or supply counters.
Designed as an OEM-style replacement or new-installation dual outlet valve for residential and light commercial plumbing supply line applications requiring a 1/2 inch Female Iron Pipe inlet with dual compression outlets.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and relieve line pressure before removing any existing valve or fitting. Compression fittings should be hand-tightened and then snugged with a wrench — do not overtighten, as brass compression seats can deform. After installation, restore supply pressure and inspect both outlet connections and the FIP inlet for leaks before closing up the work area.
