Description：
The perforate band American type worm drive hose clamp W2 is also known as screw clamp for hose. It is a mechanical device used to secure a hose onto a fitting, such as a pipe or nozzle, ensuring a tight and leak-proof connection. The material W2 typically consists of a stainless steel band with perforations and a worm gear mechanism that tightens the band when the galvanized screw is turned.
Material & Features:
W2 - Hosing and band stainless steel 201 or 301, screw carbon steel with zinc/nickel plated
The W2 American type hose clamp (screw clamp clamp for hose) features the zinc-plated screws, which forms a protective layer that shields the screw from moisture, oxygen, and other environmental factors, significantly reducing rust and corrosion. Compared to stainless steel or other anti-corrosion coatings, zinc plating is relatively inexpensive while still providing good protection.

How to choose the size:
- Method A: Measuring the Pipe's Outer Diameter
Measure the outer diameter (OD) of the pipe. If the OD is 35 mm, select a hose clamp with a 21-38 mm diameter range.
- Method B: Measuring the Pipe's Circumference
Measure the outer circumference of the pipe. If the circumference is 150 mm, calculate the OD using the formula: OD = Circumference ÷ π (≈3.14)
Example: 150 ÷ 3.14 ≈ 47.8 mm
Based on the calculated OD (47.8 mm), choose a hose clamp with a 27-51mm diameter range.
