Description：
The German style hose clamp is also know as worm screw hose clamp. It is a high-performance clamping solution designed for secure and durable hose connections in demanding applications. Featuring a solid, non-perforated stainless steel band, it ensures even pressure distribution and superior corrosion resistance, making it ideal for automotive, industrial, and marine environments.
German style hose clamp Material:
W1 - All parts carbon steel with zinc plated. (screw, hosing and band)
The zinc coating forms a dense protective layer on the steel band surface, effectively resisting moisture, acids, and other corrosive environments, significantly extending service life - making it ideal for harsh conditions. Compared to stainless steel, galvanized hose clamps maintain excellent rust resistance while offering lower costs, representing an economical and practical choice for standard industrial applications.
Both yellow zinc and white are available.
Features:
The worm screw hose clamp features the non-perforated band, which utilizes a continuous solid metal strap without screw perforations, delivering exceptional sealing integrity and uniform radial pressure distribution to ensure leak-proof performance in high-pressure or high-vibration applications. This robust design proves particularly advantageous for mission-critical systems handling fuels, hydraulic fluids, or corrosive media where maximum operational reliability is paramount.
