Description：
The galvanized hose clamps clamp (American type hose clamp) features a perforated galvanized steel band paired with a worm gear tightening mechanism, offering superior adjustability and secure fastening for hose applications. The perforations along the band reduce weight while maintaining structural integrity, ensuring even pressure distribution.
Material:
W1 - All parts carbon steel with zinc plated
How to use:
Taking the common size 21-44 as an example:
- In delivery state, the clamp’s inner diameter must exceed the maximum range (32mm) to allow easy fitting over the hose.
- When fully tightened, its diameter should remain below the minimum range (18mm) to ensure a secure, slip-free grip.
- The recommended hose outer diameter must fall within the nominal adjustment range (18-32mm) for optimal clamping performance.
