Hose Clamps
Worm-drive hose clamps quoted on clamping range, band width and material grade, with W1, W2 and W4 versions kept apart. The grade matters more than the price: a W1 clamp on a marine or road-salt application rusts through, and the leak is not covered by having bought it cheaply.

Send a drawing, a sample or an OE number and we quote this part type to it. The selection data below is what the quote is built from.
What decides the price
In order of impactW1 is all zinc-plated steel. W2 adds a stainless band. W4 is stainless throughout. Each step costs more and lasts longer in a different environment.
A clamp quoted on one diameter is a clamp that fits one hose. The range is what you stock.
9 mm and 12 mm bands press differently on a soft hose. Wide bands spread load; narrow ones bite.
Worth checking before you order
Zinc-plated steel on a road-salt or coastal application is a scheduled failure. Pay for W4 once.
Worm drive cuts into a soft hose past a point. If it still leaks, the hose or the fitting is the problem.

Questions
Which grade for a boat or a coastal site?+
W4. It is the grade that survives salt, and the price difference is small next to a failure.
Are the ranges overlapping on purpose?+
Yes, slightly, so a stock range covers the gap between sizes.
Send the specification, not the product name.
Grade, size, thread standard and coating are what a quote is built from. A product name alone produces a price that changes twice before the order.
