120 spring-action hose clamps in a 6-hole labeled plastic bin — the OEM-style constant tension clamp used on factory coolant, heater, and vacuum hoses in place of worm gear clamps. Spring clamps maintain constant radial pressure on the hose as it expands and contracts with temperature, which is why manufacturers spec them on cooling system connections where a worm gear clamp's fixed clamping force can allow micro-leaks over thermal cycles.

Best For

Automotive service shops replacing OEM hose connections — when the factory spec calls for a spring clamp, replacing it with a worm gear clamp introduces a fixed-tension point that can leak as the hose ages; this kit restores the correct clamp type
Cooling system specialists — heater core hose, upper and lower radiator hose connections, and coolant bypass hoses on many domestic and import vehicles use spring clamps from the factory
Fleet maintenance operations — mixed vehicle fleets include models from multiple manufacturers that use spring clamps in their cooling systems; having a stocked assortment prevents substituting worm gear clamps where springs are specified

Spring Clamps vs. Worm Gear Clamps

Both clamp types secure a hose onto a barbed fitting, but they behave differently in service:

Spring (constant tension) clamps — the clamp body is a spring-steel loop that is compressed with pliers to open, slid onto the hose, then released to clamp. The spring tension is self-adjusting: as the hose swells under heat or pressure, the clamp opens slightly; as it cools, the clamp follows the hose back. This prevents over-compression damage to the hose and eliminates leak points that develop as fixed-tension clamps relax over time.
Worm gear clamps — tightened to a fixed torque with a screwdriver. Provide high initial clamping force but don't self-adjust. Better for applications where the hose diameter doesn't change significantly with temperature, or where high torque retention is needed.

On cooling systems, the OEM choice is almost always a spring clamp. When in doubt, match the clamp type to what came off the vehicle. Questions? Contact us.
