Hose clamp

A worm-drive hose clamp tightens a flexible hose on a hose tail or spigot. It is chosen from the outside diameter of the fitted hose: each clamp covers a clamping range, for example 8-16 mm or 20-32 mm.

The range runs from 6 to 200 mm. Norma Torro clamps comply with DIN 3017 according to their data sheet; their asymmetric housing spreads the clamping force and the band is stamped with the material and range. The same data sheet classifies materials from W1 to W5 by minimum salt-spray resistance: 72 hours for W2, 400 hours for W4, 1,000 hours for W5. The range mainly offers W4 (Norma) and W5 (Mikalor).

For reinforced hoses, couplers and high clamping forces, see the T-bolt clamps. Below the waterline, the site's seawater intake configurator suggests two clamps at each end of the hose, chosen from the outside diameter of the fitted hose.

Brands: Norma and Mikalor.
