How to size a clip

hose OD clip band pipe clip size = hose OD = bore + (2 × wall)
1
Measure over the hose, not the pipe
A clip closes around the outside of the hose once the hose is already on its fitting. That outside diameter is the clip size — the bore the hose runs on is not.
2
Or work it out from the hose's own figures
If the hose is not to hand, take its internal diameter and add twice the wall thickness — both are listed in that hose's own Size Guide. A 19 mm bore silicone hose has a 4.5 mm wall, so it measures 28 mm across the outside.
3
Use vernier calipers, keep the largest reading
Set the outer jaws across the widest point of the assembled joint and rotate 60° between readings. Hose is soft and rarely perfectly round, so size to the biggest figure.
4
Pick the range that spans your figure
Aim for the middle of a clip's range rather than either end. Wound out near its limit a clip has little thread left to bite on; at the bottom of its range it may not open far enough to pass over the hose in the first place.
Size the clip to the hose OD, not the bore. A 19 mm hose does not take a 19 mm clip — with a 4.5 mm wall it measures about 28 mm across the outside. Every figure on this page is the outside diameter the clip closes on.

Assorted T-Bolt Hose Clamps Auto Silicone Hoses W1 Zinc Plated 2 Of Each - 46 Clips

Assorted T-Bolt Hose Clamps

What is in the assorted pack?

A spread of sizes across a single clip type in one box, so the right clip is on the shelf rather than being a trip to the merchant. Available in 2 of each - 46 clips, 5 of each - 115 clips, 10 of each - 230 clips, 2 of each - 42 clips, 5 of each - 105 clips and 10 of each - 210 clips.

Why buy assorted rather than single sizes?

Because you rarely know in advance which size the next job needs. For a workshop, farm or van, having the range on hand is worth considerably more than the price difference.

Are they good value?

Per clip, substantially cheaper than buying the same clips as singles, and the larger boxes are better value again. Singles only make more sense when you know exactly which size you need and will never need the others.

W1 or W4?

Available in W1 Zinc Plated and W4 Stainless Steel. W1 is zinc-plated steel - cheaper, fine for dry indoor use. W4 is stainless throughout, band, housing and screw, which is what you want for weather, coolant, road salt or a marine environment.

What sizes does the box cover?

The full stocked size range for this clip type is included in the box.

How do I choose the right clip from the box?

Size to the outside diameter of the hose once fitted over the pipe, not the bore, and aim for the middle of the clip's adjustment range rather than either extreme. A clip at the end of its travel has almost no thread engaged.
