Constructed from 304-grade stainless steel with zinc-plated hardware, they resist rust and support repeated assembly and disassembly for maintenance or upgrades. The unitized band design reduces weight while keeping clamp loads even across the joint.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these clamps secure a 4\" butt or lap joint?\u003c\/h3\u003e\n\u003cp\u003eThe clamps wrap around the mating pipe ends and tighten uniformly to compress the joint, producing a reliable mechanical seal without deforming the pipe. Their single-piece band and integrated fastener give consistent pressure along the circumference for a snug fit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned specifically for 4\" OD to 4\" OD butt or lap joints.\u003c\/li\u003e\n  \u003cli\u003eUnitized band minimizes moving parts and simplifies installation.\u003c\/li\u003e\n  \u003cli\u003eHigh clamp loads distribute force to prevent pipe distortion.\u003c\/li\u003e\n  \u003cli\u003eCompatible with pipes, mufflers and catalytic converter connections.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these clamps resist corrosion in road and exhaust environments?\u003c\/h3\u003e\n\u003cp\u003eYes — the shell and band use 304 stainless steel for baseline corrosion resistance, while fasteners receive zinc plating to further reduce rust risk.
