Made of a heat-sensitive material, Gates PowerGrip™ SB clamp solves coolant leakage problems in both silicone and standard rubber wall hoses, even on out-of-round fittings.

• Gates thermoplastic clamp maintains a dynamic tension so that it never needs retightening. Whenever the engine reaches operating temperture, the shrink forces of PowerGrip SB readjust to a consistent clamping force. In addition, its clamping force increases as the temperature drops below 40 degrees F, thereby tightening the connection.
• Cold leaks, which normally occur when the temperature drops below 40 degrees F, are eliminated.
• Installation using a heat gun is fast and easy, including hard-to-reach places. Heat-gun attachments permit installation in confining areas that would be extremely difficult to reach using a screwdriver on conventional orm-drive screw clamps.
• The PowerGrip SB hose clamp features a smooth surface that won't rust, corrode, or result in cut fingers during installation.
• PowerGrip SB hose clamps are completely resistant to all automotive fluids including oil, antifreeze and even brake fluid.
• Wider than conventional clamps, PowerGrip SB hose clamps can be positioned over the raised bead on the end of the fitting nipple - even cast metal.
• PowerGrip SB clamps are readily removed with Gates' specially-designed clamp removal tool. The clamps also can be removed using a soldering iron to melt through the thermoplastic material.
• Sizes are available for 1/4 through 3-1/8 inch I.D. hose.
