Heat-Shrinkable Hose Clamps

Gates® PowerGrip™ SB clamps are engineered with a heat shrinkable tube material that secures hoses more tightly and effectively than traditional metal clamps. The wide clamp construction eliminates damage caused by over-tightening, with a thermoplastic material that's proven to perform in even the harshest of automotive and heavy duty cooling system applications.

Just Add Heat.

Using only a standard heating gun, you can install your PowerGrip™ SB hose clamp in minutes. Simply place your clamp onto the hose, work the hose to completely cover the fitting, and apply heat evenly around the clamp until it shrinks tightly over the hose.
