Gates

1.75″ – 2″ inside diameter shring range. Generally works well with 1.5″ ID hose.  Sold individually.

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.

Gates PowerGrip SB Clamps are maintenance-free, durable hose clamps that retain dynamic tension for any shape of hose and housing, even on out-of-round fittings and applications, to reliably stop leaks without the need for re-tightening. They’re designed for a secure, tight fit in extreme operating temperatures to eliminate antifreeze leaks and groundwater contamination.

Features:
Can be used with all brands of silicone hose
Wider sealing area entraps connector bead
Easy to install with ordinary heat gun
Heat-sensitive thermoplastic with a memory to prevent over- or under-tightening
Conform to any shape of hose and housing, even out-of-round fittings
Temperature Range: -40°C to +150°C (-40°F to +302°F)
