A ABIGAIL 2.5" Exhaust Butt Joint Clamp 2 PCS — 2.5" OD Stainless Steel Sleeve with Steel Gasket & M10 Bolt

This paired exhaust coupler by A ABIGAIL is built for reliable pipe-to-pipe connections on mufflers, catalytic converters and exhaust sections where a tight, reusable clamp is preferred over welding. Constructed from 304 stainless steel with a zinc-plated M10 bolt and nut, the sleeve uses a steel gasket and an aluminum alloy I-block to deliver a solid mechanical seal while allowing future disassembly for maintenance.

How does this clamp create a leak-resistant connection?

The design compresses a steel gasket around the junction of two 2.5" OD pipes, using the aluminum I-block to distribute clamp load evenly without crushing the pipe. The M10 flange bolt and nut let you dial in clamping force for a consistent fit.

• 304 stainless steel band resists corrosion and retains tension.
• Steel gasket forms a tight seal around pipe OD without welding.
• Aluminum I-block prevents strap distortion under torque.
• Zinc-plated hardware improves bolt thread durability.

Will this clamp fit my exhaust system and how is size measured?

This coupler is sized to join two pipes that each measure 2.5" outside diameter (OD). The strap width is approximately 3" (76.2 mm), providing surface contact for the gasket and even compression across the joint.

• Designed specifically for 2.5" OD to 2.5" OD pipe joints.
• 3" strap width supports stable clamping and sealing area.
• Sold as a set of two clamps for multi-point repairs or spares.

How easy is installation and future service?

Installation requires only common hand tools: tighten the M10 bolt to compress the gasket and secure the pipes. No welding or special fabrication is necessary, and the clamp can be removed later for servicing or replacement.

• Hand-tool installation—no welding required.
• Reusable design preserves pipe condition when removed.
• Tested for strength and designed to resist loosening under vibration.

What applications and components is this clamp suitable for?

The clamp works with a wide range of exhaust components where a butt-joint connection is needed, including mufflers, catalytic converters, resonators and flex pipes. It’s meant for mechanical joining and repair, not as a structural mounting bracket.

• Compatible with mufflers, catalytic converters, resonators, flex pipes, and tips.
• Ideal for repair jobs, retrofits and temporary or permanent joints.
• Not intended as the primary support for heavy assemblies; use hangers where needed.

Who is this for: This A ABIGAIL 2.5" butt joint clamp is for mechanics, DIY enthusiasts and repair shops that need a corrosion-resistant, reusable coupler to join two 2.5" OD exhaust pipes quickly and securely. It’s suited to anyone wanting a non-welded repair option for mufflers, catalytic converters or exhaust mid-sections that balances reliable sealing, ease of installation and future serviceability.
