Quarter Ball builds frost-proof ball-valve sillcocks and gas valves for residential and commercial plumbing. The traditional sillcock's weak points - compression washers, ceramic discs, O-rings - are replaced with a solid brass cartridge and a chrome-plated solid brass ball.

The result is an exterior faucet built to survive decades of freeze-thaw cycling without the callbacks that come from worn washers. Every anti-siphon model ships with dual backflow protection built in, so it meets hose-bib code requirements without a separate vacuum breaker.
