ABA
ABA is the Swedish hose clamp maker. Autotools stocks ABA NOVA hose clamps across a wide range of diameters, plus rubber-lined clamps for pipes and cables.
NOVA clamps hold coolant, fuel and air hoses on cars, boats and machinery. They come in workshop packs, so the common sizes stay on the shelf.
Picking the size
Measure the outside diameter of the hose where it sits on the fitting. Each clamp lists its range, such as 11 to 17 mm. Choose the one where your measurement falls near the middle, so the clamp has room to tighten either way.
