Power Grip Clamp 1-3/4in to 2in

The ALLSTAR PERFORMANCE Power Grip Clamp 1-3/4in to 2in (SKU ALL 30257) is a heavy-duty hose clamp designed for securing coolant, heater, and fuel lines in high-temperature and high-vibration engine environments. This single-unit clamp features a heat-shrink rubber liner that grips hose material firmly while preventing damage to the underlying tubing—a critical advantage in racing, automotive restoration, and performance engine builds where line integrity under pressure is non-negotiable.

The 1-3/4 to 2-inch clamping range accommodates standard hose diameters across most small-block and mid-size engines, while the power-grip band design distributes clamping force evenly around the hose circumference, reducing the risk of localized crushing or leakage that can occur with inferior clamp designs. The rubber liner cushions the band against the hose outer surface, protecting against abrasion and corrosion while maintaining a secure seal even as thermal expansion and engine vibration cycle the assembly repeatedly over thousands of miles.

This clamp is essential for engine builders, weekend fabricators, and restoration shops managing custom cooling and fuel systems where stock clamps fall short. The compact design (4.05 x 2.15 x 4.05 inches) fits tight engine bays, and the light weight (0.06 lbs) adds nothing to overall system weight. Whether upgrading an old radiator installation, securing a new heater line, or building a high-performance fuel delivery system, the Power Grip Clamp meets the practical demands of serious automotive work.
