CONSTANT TORQ CLAMP 3-3/4 - 4-5/8

The CONSTANT TORQ CLAMP 3-3/4 - 4-5/8 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 all stainless steel clamp features an extended inner liner that covers worm gear slots, protecting against extrusions and damage. With its extended adjustment range, this clamp allows for fewer stocked parts, providing complete coverage. Trusted by top fleets, this clamp is a practical and reliable solution for new vehicle installations. Sold individually, it fits most makes and models.
