Secure your brewing tubing connections with the Craft a Brew Beer Hose Clamp in 1/2", a reusable stainless steel clamp sized to fit 1/2" outer diameter tubing. It creates dependable, leak-resistant connections across a range of brewing and fermentation setups. Unlike traditional worm clamps, the smooth banded interior helps reduce the risk of pinching or cutting soft tubing during installation and tightening. The ergonomic plastic turn key lets you tighten or loosen by hand—no screwdriver or dime required—so it’s easy to disconnect and reconnect tubing when it’s time to sanitize. Use it with transfer tubing, pumps, wort chillers, kegging systems, and other tubing-based brewing equipment wherever you’re running 1/2" outer diameter tubing. Please note this clamp fits 1/2" outer diameter tubing. If your tubing has a 1/2" inner diameter (roughly 3/4" OD), choose the 3/4" Beer Hose Clamp instead. Designed for repeated homebrewing use, this reusable clamp is a practical, tool-free upgrade over standard worm clamps.
