B & K 1/2 in. x 6 in. Anti-Siphon Frost-Free Sillcock Valve

The B & K anti-siphon frost-free sillcock valve is engineered to provide reliable outdoor water service while protecting against freezing temperatures. Its integrated backflow preventer stops siphoning back into the potable water supply, and the valve automatically drains upon shut-off to prevent freeze damage. Constructed with a heavy-duty chrome-plated brass body and tube, this valve features a built-in lockshield and a sturdy six-point cast iron handle for smooth operation and long service life. It complies with ASSE standard 1019, ANSI/NSF 61-9, ANSI B1.20.1 threaded ends, ANSI B1.20.7 hose threads, and ANSI B16.18 solder ends.
