Hey DIYers or plumbers, need a reliable shut-off valve? This BrassCraft R14X is a workhorse. It's a straight valve, which is the type you typically use when the water pipe comes up from the floor to supply a toilet, sink, or appliance. The inlet side is 1/2 inch nominal and uses a 'sweat' connection, meaning you solder it onto a copper pipe. The outlet side is 3/8 inch O.D. (outside diameter) and uses a compression fitting – that's where you tighten a nut onto a supply line (like the flexible hose to your toilet or faucet). It's a multi-turn valve, so you twist it several times to fully open or close the water flow. Made by BrassCraft, a trusted name in plumbing. Essential for repairs, renovations, or just replacing an old, leaky valve under your sink. Always make sure your pipe sizes match before you buy!
