Hose couplings

Worm-drive hose clamps in four ranges, covering hose from 8 mm to 265 mm. ASFA is the general-purpose clamp, 9 mm band, 8–12 mm up to 140–160 mm. GBS is the heavy-duty one for thick reinforced hose on agricultural, marine and biogas work, with three welding points on the larger sizes and a band range to 253–265 mm. MINI seals small thin-walled hose from 7–9 mm, with a smooth inner face so it grips a petrol line without cutting it. ST ORIGINAL takes a 9 mm or 12 mm band and locks in a seamless moulded housing that resists slipping. Every range comes W1 zinc-plated as standard; W2, W4 and W5 stainless are available to order, as are band widths and sizes outside those listed. All four have rolled band edges and a smooth underside, which is what stops a clamp cutting into the hose it is holding.
