3 Piece Hose Clamp Pliers Set

When a cooling system repair or heater core swap demands that you stop flow through a flexible hose without disconnecting it, the right pinch-off plier makes the job clean and controlled. This tray puts three sizes at your fingertips so you can match the tool to the hose rather than forcing a single plier to do everything.

The smallest plier handles hoses from 6 mm to 19 mm — vacuum lines, small coolant crossover tubes, and similar applications. The mid-size plier covers 6 mm to 32 mm, taking on typical radiator and heater hoses found in most passenger vehicles. The largest plier spans 19 mm to 57 mm for bigger flexible lines encountered on trucks, heavy equipment, and industrial setups.

All three are plastic, which means they grip the hose wall without the sharp edges or concentrated pressure points that metal jaws can introduce. That helps preserve hose integrity so you can reuse the line after the repair instead of cutting it out and replacing it.

The red tool tray is designed for the Teng Tools TT system. Slide it into a roller cabinet drawer, set it on a service cart, or lay it on the fender cover next to the engine. Each plier sits in a molded pocket, making it obvious which size you have grabbed and which slot is empty when you pack up. Total weight for the loaded tray is 478 g, light enough to carry comfortably with one hand.

Three pliers covering 6 mm to 57 mm. One tray. Everything you need to isolate flexible hoses across a wide range of automotive and general maintenance tasks.
