Gates 32990 Power Grip Thermoplastic Hose Clamp 3-1/2" to 3-5/8" OD

The Gates 32990 Power Grip Hose Clamp is a maintenance-free, heat-shrink clamp engineered for superior sealing performance. Made from a heat-sensitive thermoplastic material with built-in memory, this clamp automatically conforms to the shape of the hose and housing for a precise, leak-free seal — even on out-of-round applications.

Unlike traditional worm-gear or screw-type clamps, the Power Grip clamp retains dynamic tension throughout its service life, eliminating the need for retightening. Simply apply heat with an ordinary heat gun and the clamp shrinks to form, providing consistent clamping force across all conditions and temperature extremes ranging from -40°F to 302°F.

Key Features:

• Fits hose outer diameter (O.D.) of 3-1/2" to 3-5/8"
• Maintenance-free design — never needs retightening
• Retains dynamic tension to prevent leaks over time
• Wider sealing area entraps connector bead for a secure hold
• Conforms to any shape of hose and housing, including out-of-round applications
• Heat-sensitive thermoplastic with memory prevents over- or under-tightening
• Built-in visual indicator confirms clamp has shrunk to proper seal
• Easy installation using a standard heat gun
• Temperature rated from -40°F to 302°F (-40°C to 150°C)
• Sold individually

The Gates Power Grip Clamp is ideal for demanding under-hood and cooling system applications where reliable, long-term sealing is critical. Trust Gates engineering to keep your connections secure in even the most extreme operating conditions.
