A ABIGAIL 4.0" Exhaust Clamp 4" Butt Joint Band Clamp — 2 PCS Stainless 3" Wide, 304 SS Corrosion-Resistant

A ABIGAIL 4.0-inch stainless steel butt joint band clamp creates a tight, reusable seal between 4" exhaust pipes, mufflers, and catalytic converters without welding.

This heavy-duty coupling is built from 304 stainless steel with a zinc-plated M10 flange bolt, steel gasket and aluminum alloy I-block to deliver corrosion resistance and dependable clamping force. Designed to join two 4" OD exhaust sections, the 3-inch wide strap compresses evenly around the joint so you can repair, replace or service exhaust components quickly while preserving pipe alignment.

How does this clamp keep exhaust joints sealed and rattle-free?

The clamp combines a contoured gasket and a wide band to create consistent surface pressure around the pipe circumference. Tightening the M10 bolt compresses the gasket and strap against both pipe ends, reducing leaks and vibration without bending the tubing.

• 304 stainless steel band resists rust for long service life
• Steel gasket provides a conforming seal along uneven mating surfaces
• Zinc-plated fastener prevents thread corrosion for easier removal
• 3-inch strap width spreads clamping force to avoid pipe distortion

Which exhaust parts and repairs is this clamp suitable for?

This butt joint band clamp works for a wide range of exhaust repairs and assemblies. Use it to join mufflers, catalytic converters, resonators, flex pipes and tailpipes where two 4" outer-diameter sections meet.

• Ideal for muffler and tailpipe repairs on cars, trucks and custom exhausts
• Fits 4.0" OD pipe to 4.0" OD pipe connections
• Reusable for temporary or permanent fixes without welding
• Useful for aftermarket and replacement exhaust components

How easy is installation and future service with this clamp?

Installation requires only standard hand tools to tighten or loosen the M10 flange bolt—no welding or special equipment needed. The clamp can be removed and reinstalled for routine maintenance, part swaps or inspections while maintaining a strong clamp load.

• Hand-tool install — tighten bolt until gasket compresses
• No welding reduces shop time and keeps parts replaceable
• Reusable design tested for repeated use without metal fatigue
• Compact profile fits tight undercarriage spaces

What are the material and dimensional details I should know?

Components are selected to balance corrosion resistance and mechanical strength. The band is 304 stainless steel, the bolt is zinc-plated M10, and an aluminum alloy I-block aligns the strap; the band width is approximately 3 inches to support even clamping.

• Fits two 4.0" (4-inch) outer-diameter pipes
• Strap width: 3.0 inches (≈76.2 mm)
• Includes gasket and mounting hardware for one clamp per package
• Sold as single-piece per listing; compatible with standard exhaust sizes

Who is this for: The A ABIGAIL 4.0-inch butt joint band clamp is ideal for mechanics, home DIYers and custom exhaust builders who need a corrosion-resistant, serviceable coupling for 4" exhaust systems. Choose this clamp when you want a durable, weld-free repair or a removable joining solution that preserves pipe alignment and simplifies future servicing.
