DIYUK W2 Stainless Steel Worm Drive Hose Clips, Adjustable Pipe Clamps, 8-210mm, 18 Sizes
20% off applied
Overview
W2 stainless steel worm drive hose clamps in 18 sizes, from 8-12mm (0.31-0.47in) up to 190-210mm (7.48-8.27in), for a secure, adjustable grip on hoses, ducting and pipes in plumbing, HVAC and workshop jobs.
The band and housing are stainless steel, giving strong resistance to rust and general weathering compared with a fully galvanised clamp of the same size. The screw is zinc-plated steel rather than stainless.
The worm drive mechanism itself - a screw thread engaging an embossed band, 9mm (0.35in) wide and 0.7mm (0.03in) thick - allows fine, even tightening across the full clamping range. A recommended torque of 4.0 Nm (approx. 35 lbf·in) is specified as a guide to correct fitting without overtightening.
Key Features
- W2-grade hybrid construction: stainless steel band and housing for strong resistance to rust and general weathering
- Zinc-plated steel screw
- Worm drive tightening mechanism for fine, even adjustment right across the clamping range, rather than fixed steps
- Slim 9mm (0.35in) wide, 0.7mm (0.03in) thick band, keeping the clamp low-profile once fitted
- Clamping range embossed on the band, so each size is easy to identify
- Recommended tightening torque of 4.0 Nm (approx. 35 lbf·in), to guide correct fitting without overtightening
- Supplied across 18 clamping-diameter sizes from 8-12mm (0.31-0.47in) up to 190-210mm (7.48-8.27in)

Full size range (clamping diameter): each size is named by its closed and fully-open clamping diameter - for example, a 16-25mm clamp closes down to 16mm and opens as wide as 25mm - so choose the row whose range comfortably spans your measured diameter, ideally with the screw still short of the end of its travel once tightened.

Choosing a size: measure the outer diameter of the hose once it's fitted over the connector it will be clamped to (not the hose alone) - it should close within its stated range with the screw still able to turn, not at the very end of its travel. If the measured diameter falls close to the top of one clamp's range, it's worth sizing up so the band still has clamping force in reserve once seated.
Typical Applications
- HVAC and ducting connections, securing flexible ducting and hose runs onto spigots and connectors
- General domestic and agricultural plumbing, including washing machine drain hoses, wherever a flexible hose or pipe needs clamping onto a barbed or ridged fitting rather than being solvent-welded or compression-jointed
- General workshop and light industrial hose and pipe fastening, with the mid-to-large sizes (40-60mm up to 190-210mm) suited to larger-bore hose and ducting
Installation Guidance
Slide the open clamp over the hose before pushing the hose onto its fitting - it's much harder to thread a clamp on afterwards once the hose is seated. Push the hose fully home on the barb, then centre the clamp over the ridged or barbed section of the fitting so the band sits on the reinforced part of the hose rather than overhanging its end. Tighten evenly to around 4.0 Nm (approx. 35 lbf·in), turning the screw steadily rather than in short bursts and checking the hose hasn't twisted or ridden up the fitting as the band closes.
Common Questions
Which size do I need?
Measure the hose once it is fitted over its connector, then choose the size whose range spans that diameter. Each size is named by its closed and fully open diameter, for example 16-25mm.
Is the whole hose clamp stainless steel?
The band and housing are stainless steel; the screw is zinc-plated steel.
How tight should I make it?
Tighten evenly to around 4.0 Nm (approx. 35 lbf·in), the recommended torque.
How do I tell the sizes apart?
The clamping range is embossed on every band, for example 100-120.
