Made from marine-grade T304 stainless steel and fitted with high-strength American standard bolts, they provide even compression around the joint and prevent pipe distortion. The kit includes two 4\" clamps sized for pipes with approximately 2 mm wall thickness and a 3\" strap width — measure your pipe outer diameter before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this clamp create a leak-free joint?\u003c\/h3\u003e\n\u003cp\u003eThe clamp uses a wrap-around band and an exclusive reaction block that spreads tightening force evenly 360°, so the seal closes uniformly around the pipe. Its lap-joint design avoids high-point pressure that can twist or deform the pipe, while the included carbon steel gasket helps fill microscopic gaps.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e360° reaction block distributes clamping pressure evenly\u003c\/li\u003e\n  \u003cli\u003eCarbon steel gasket improves sealing against leaks\u003c\/li\u003e\n  \u003cli\u003eDouble-stack self-locking washers and nut resist loosening under vibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these fit my exhaust system and how do I measure?\u003c\/h3\u003e\n\u003cp\u003eThese clamps are made to join a 4\" outer-diameter pipe to a 4\" inner-diameter pipe where wall thickness is about 2 mm. For a reliable fit, measure the outer diameter of the larger pipe at the point of connection and compare to the clamp specification. If pipe walls differ significantly, choose a clamp sized to the actual outer diameter you measured.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for 4\" OD to 4\" ID pipe connections with ~2 mm wall thickness\u003c\/li\u003e\n  \u003cli\u003eStrap width: 3\" for wide bearing surface\u003c\/li\u003e\n  \u003cli\u003eMeasure the pipe OD precisely before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow durable and corrosion-resistant are these clamps?\u003c\/h3\u003e\n\u003cp\u003eConstructed from T304 stainless steel and tested to 100 hours of salt spray, these clamps resist rust and maintain strength in harsh environments.
