Hose clamp
Hose clamps are components that tighten a hose onto a fitting or pipe spigot to secure it and prevent it from coming off or leaking fluid. They are also called hose clamps. Main types include the worm-gear type, which tightens a band with grooves engaged by a screw; the wire type, which wraps a metal wire and tightens it with a screw; and the spring type, which tightens using the restoring force of a spring. Spring types readily follow expansion and contraction of hoses caused by temperature changes and are used in applications such as automotive coolant piping. Materials include carbon steel with zinc plating or other surface treatments, as well as corrosion-resistant stainless steel such as SUS304. They are widely used for hose connections on equipment and machinery in piping for water, air, oil and other fluids.

How to choose Hose clamp
-
1. Select a clamping range that suits the hose outer diameter
The clamping range is the range of hose outer diameters the clamp fits, which is 4 to 200 mm for the listed products. Measure the hose outer diameter after insertion and select a size where that value falls near the middle of the range to allow a margin in clamping allowance. At the ends of the range, clamping may be insufficient or excess band length may protrude.
-
2. Choose a type suited to the application
Worm-gear types have a wide clamping range and are easy to retighten. Wire types tighten with a thin wire and are suited to small-diameter hoses. Spring types can maintain clamping force when the hose shrinks due to temperature changes, and some are designed to tighten evenly around the full circumference.

3. Determine the material according to the operating environment
Carbon steel types are inexpensive but require anti-rust treatment. For wet areas, outdoor use or environments exposed to chemicals, stainless steel types such as SUS304 are suitable. Also be aware of corrosion caused by the combination of materials with fittings or threaded parts.
-
4. Check the anti-rust surface treatment
For carbon steel types, corrosion resistance varies depending on the presence and type of treatments such as zinc plating or Geomet treatment (zinc-aluminum-based anti-rust coating). In humid or salty environments, check the type of treatment before selecting.
-
5. Check contact with the hose by wire diameter and band width
The wire diameter of wire types is 1 to 2.3 mm for the listed products. Thinner wire fits smaller hoses but raises contact pressure and can more easily dig into soft hoses. For band-type clamps, a wider band distributes the clamping force and is less likely to damage the hose.
-
6. Tighten to the recommended torque
Overtightening can cause hose damage or breakage of threaded parts, while insufficient tightening causes leaks or disconnection. For products where a recommended tightening torque is specified, tighten to that value using a torque driver or similar tool.
