CONSTANT TORQ CLAMP 4-1/4 - 5-1/8

The CONSTANT TORQ CLAMP 4-1/4 - 5-1/8 is a highly recommended product for bus, truck, and heavy-duty equipment air intake and coolant connections. Its patented belleville spring design eliminates "cold flow hose leaks" by automatically adjusting the diameter for hose compression set or expansion/contraction due to temperature changes. This clamp is specified by many top fleets for new vehicle installations and features an extended inner liner that protects against extrusions and damage. With its all stainless steel construction and extended adjustment range, it allows for fewer stocked parts, providing complete coverage. Sold individually, it fits most makes and models.
