Gates® PowerGrip® SB Hose Clamp
Thermoplastic Clamps For Maintenance-Free Hose Connection

Don't trust your engine to just any hose clamps. Get a grip and get the revolutionary Gates® PowerGrip Hose Clamps. Gates® thermoplastic clamp maintains a dynamic tension so that it never needs retightening. Whenever the engine reaches operating temperature, the shrink forces of PowerGrip SB readjust to a consistent clamping force. Cold leaks, which normally occur when the temperature drops below 40 degress Farenheit are eliminated. Installation using a heat gun is fast and easy, including hard-to-reach places. The PowerGrip SB hose clamp features a smooth surface that won't rust, corrode, or result in cut fingers during installation. Those clamps are completely resistant to all automotive fluids including oil, antifreeze and even brake fluid.



- Be sure vehicle engine is turned off and has cooled down.
- Drain coolant.
- Remove old hoses.
- Clean metal stems with wire brush.
- Remove clamp from brace by squeezing, then folding the brace in half and removing it.
- Place clamps over each end of new hose.
- Position hose over fitting.
- Slide clamp over top of fitting bead. Be sure to position so the print on clamp is facing up and in full view.
- Apply heat as follows:
- Use standard heat gun with settings on high.
- Do not use open flame to apply heat.
- Do not apply heat to one spot too long. Move gun continuously.
- Continue until shrinking is complete.
- Check connections to be sure a good seal was made by trying to turn the hose.
- Replace coolant.
- Start engine and check for leaks. If leaks appear, apply more heat to clamp.
