This 3 inch lap joint exhaust clamp is designed to connect a 3” OD pipe to a 3” ID pipe in exhaust repair,applications. With a strap width of 2.95 inches (74.9 mm) and an approximate band thickness of 0.025 inch (0.6 mm), it is suitable for overlapping pipe connections that require a secure hold. Made of T304 stainless steel, the clamp and exhaust pipe offers resistance to rust, corrosion, and heat for long-term use in exhaust system environments. The I-block reaction structure helps distribute clamping force more evenly around the pipe connection area, supporting a tighter and more secure fit. Pre-installed hardware allows for easier installation and removal. For more even pressure distribution, tighten the two bolts gradually in an alternating pattern during installation. Each package includes 2 exhaust clamps and 1 exhaust pipe。 Please measure your pipe dimensions carefully before purchase.
