The Micro Matic 1/2" Stepless Hose Clamp is the professional choice for permanent, leak-proof tubing connections in draught and gas systems. Unlike standard worm-gear clamps, the Oetiker-style stepless design provides a 360-degree uniform seal with consistent compression, preventing the "bunching" of tubing that causes slow gas leaks. Constructed from high-quality 304 stainless steel, it is resistant to rust and corrosion, making it ideal for the high-moisture environments of kegerators and commercial beverage rooms.
