Hose clamp pliers grip a clamp so you can squeeze it open, slide it along the hose and hold it there. Spring clamps, flat band clamps and ear type clamps all use different jaws. A long cable pair reaches clamps hidden behind other parts, while a short pair is easier to control on an open clamp.
The six picks below run from a nine piece set to single cable and locking pliers. Sizes, materials and weights come from each listing page and are the makers’ own claims. We have not used these tools ourselves. Where a listing disagrees with itself on a size or model number, we say so.

The 6 Best Hose Clamp Pliers
1. BETOOLL 9pc Hose Clamp Pliers
A nine piece set in a case with long reach cable pliers, Clic-R collar pliers, swivel jaw band clip pliers, spring wire clip pliers, regular and angled flat band pliers, hose removal pliers, a dual-headed screwdriver and a hose hook. The listing says to recognize the BETOOL brand and names SZBRT as the manufacturer, and the shipping weight is 6.4 pounds, so the naming is not consistent.
Suits: mixed jobs on coolant, fuel and oil hoses. Strengths: many clamp types in one case. Weaknesses: plastic material is listed and no size range is stated. Skip it if you only need one pair.
2. Toolwiz Hose Clamp Plier with Locking Device
A single pair of heavy duty carbon steel flat band pliers with a PVC handle, a locking device and a rotating tip for tight angles. The maker says the maximum opening is 1.38 inches (35 mm) and the length is 215 mm, while the table gives 1.2 by 2.2 inches, so the dimensions do not line up.
Suits: removing and fitting flat or ring type clamps. Strengths: a lock and a rotating tip. Weaknesses: conflicting size figures. Skip it if you need a long cable reach.

3. Astro Pneumatic Tool 94093 Multi-Cable Hose Clamp Pliers
Pliers on a flexible cable for clamps that are hard to reach. The maker says they handle plastic or metal self-tightening clamps from 11/16 to 2-1/2 inches (18 to 54 mm) and can be locked to free up your hands, with a threaded adjustment to set the last locking tooth. The item weighs 11.2 ounces with a one year warranty. The model number shown is 9409A against 94093 in the title.
Suits: clamps buried deep in an engine bay. Strengths: a stated clamp range and a lock. Weaknesses: the model number differs by one digit. Skip it if you prefer short rigid pliers.

4. GEARWRENCH Cable Hose Clamp Pliers 82115
Cable pliers in alloy steel with a plastic handle that the maker says work on clamps from 0 to 2 inches and from 1 to 3 inches. The listing names ASME B107.500, a limited lifetime warranty and a weight of 1.1 pounds. The length shows as 36 inches, which is the cable run rather than a solid body, so treat it as approximate.
Suits: difficult to reach clamps. Strengths: two clamp ranges and a long warranty. Weaknesses: sparse details in the bullets. Skip it if you want a short, rigid tool.

Care and Setup
- Match the jaw type to the clamp type before you squeeze.
- Follow the vehicle maker’s instructions for any hose or coolant work.
- Wipe oil from the handles and jaws after use.
- Store cable pliers coiled loosely so the cable does not kink.
Mistakes to Avoid
- Using flat band pliers on a clamp that needs a collar tool.
- Ignoring the stated clamp diameter range.
- Bending the cable tightly while it is under load.
- Buying a nine piece set when one pair would do.

When are cable hose clamp pliers useful?
When the clamp sits behind other parts. The flexible cable lets you squeeze the jaws from a position where a rigid handle will not fit.
Which pairs list a locking feature?
