A ABIGAIL 4.0" Exhaust Band Clamp for 4" OD Pipes — 304 Stainless Steel, 3" Strap, Reusable Butt-Joint

A ABIGAIL's 4.0-inch stainless steel butt-joint exhaust clamp securely joins 4" OD exhaust components for a reusable, no-weld connection.

This heavy-duty band clamp is built from 304 stainless steel with a zinc-plated M10 flange bolt, steel gasket and aluminum alloy I-block to give a reliable, tight seal on mufflers, catalytic converters and exhaust piping. Designed to join two 4" outer-diameter pipes, the clamp replaces welded repairs and simplifies service by allowing disassembly without distorting the exhaust parts. It ships as one clamp and is suitable for professional garages and DIY repairs alike.

How does this clamp create a leak-resistant connection?

The clamp uses a formed steel band and internal gasket to press evenly around mating pipe ends, reducing gaps that can leak exhaust gases. The I-block distributes bolt torque so the seal tightens uniformly and avoids crushing thin-walled pipes.

• 304 stainless band resists corrosion and holds shape under heat.
• Steel gasket conforms to pipe irregularities for better sealing.
• Zinc-plated M10 flange bolt provides strong, rust-resistant clamping force.
• Aluminum alloy I-block spreads load to prevent pipe distortion.

Will it fit my exhaust system and what are the dimensions?

This clamp is sized to join two pipes that each measure 4.0 inches (outside diameter). The strap width is 3 inches (76.2 mm), giving broad contact area for a stable joint. Verify the OD of your pipes and any overlapping sleeve clearance before ordering.

• Fits 4.0" OD pipe to 4.0" OD pipe joints.
• Strap width: 3.0" (76.2 mm) for increased sealing surface.
• Includes one butt-joint band clamp per package; sold as single-piece pack.
• Suitable for typical muffler, converter and resonator connections.

How easy is installation and future service?

Installation requires only common hand tools—tighten or loosen the M10 flange bolt to secure or release the clamp. Because the clamp does not require welding, it speeds repairs and allows repeat removal for maintenance or part replacement without harming the pipes.

• No welding or special tools needed — just a wrench for the M10 bolt.
• Reusable design tested for strength and repeat service cycles.
• Removes risk of heat damage from on-vehicle welding operations.
• Works well for temporary fixes or permanent clamped joints if installed correctly.

What applications and vehicles is this clamp appropriate for?

Use this band clamp wherever two 4" OD exhaust components meet: mufflers, resonators, catalytic converters, flex pipes and tips. It's a common choice for light trucks, performance systems and aftermarket exhaust repairs that require a robust, detachable joint.

• Muffler and resonator connections in aftermarket systems.
• Catalytic converter and exhaust manifold service junctions.
• Exhaust tips, flex pipes and short splice repairs.
• Professional shops and home garages performing clamp-style repairs.

Who is this for: A ABIGAIL's 4.0-inch butt-joint band clamp is aimed at mechanics, exhaust specialists and experienced DIYers who need a corrosion-resistant, reusable clamp to join 4" OD exhaust components without welding. If you want a strong mechanical connection that simplifies future servicing while protecting thin exhaust tubing from distortion, this clamp is a practical addition to your parts inventory.
