Gates PowerGrip SB Clamp Fits Hose OD 3 1/2 to 3 5/8 Nominal Hose ID 3 1/8

This Gates PowerGrip SB clamp is built with a strong, corrosion-resistant stainless steel band and housing, designed to hold securely onto hoses with an outside diameter ranging from 3 1/2 to 3 5/8 inches. The nominal inside diameter it's meant for is 3 1/8 inches, making it a solid choice for securing various coolant or air intake hoses where a reliable connection is needed.

The unique screw-tightening mechanism allows for a precise fit, ensuring a leak-free seal without damaging the hose. This type of clamp is often used in applications where a standard worm gear clamp might be too bulky or prone to loosening over time due to vibration or temperature changes. Its robust construction means it will stand up to the demands of an engine bay.
