Worm drive hose clip W1 50 to 70 mm, 9 mm band

The worm screw pulls the band around the hose and presses the rubber onto the barbs of the tail. W1 grade to DIN 3017: band, housing and screw are all zinc-plated steel, which is plenty inside a dry workshop.

Choose on clamping range, measured over the hose as it sits on the tail. If your size lands right at the bottom of the range, take the size below; a band that is nearly closed has no adjustment left for a retighten. Tighten until the rubber just starts to bulge through the slots and stop there.
