Granatelli Motor Sports - 1.50-Inch Billet Aluminum Hose Clamps

Upgrade your cooling, fuel, or intake connections with the precision and durability of the 1.5-inch (38mm) Billet Aluminum Hose Clamps featured on this page. Designed for a secure, even clamping force, these billet aluminum clamps help prevent leaks, blown-off hoses, and pressure loss in high-performance and street-driven vehicles. Each clamp is CNC-machined for strength and consistency, then finished for both corrosion resistance and style. Available in polished, red, blue, green, and black anodized options to match your engine bay. Hose clamps should be replaced whenever you notice signs such as cracking hoses, coolant or fuel seepage, loss of clamp tension, corrosion, or after repeated removal during maintenance, as worn clamps can no longer maintain proper sealing force. Choosing high-quality billet clamps ensures a tighter seal, longer service life, and the confidence that your hoses stay exactly where they belong, even under heat, vibration, and pressure.
