ETL INDUSTRIES 4" Exhaust Clamp 2-Pack — 4-inch Narrow Band T-304 Stainless, Pre-attached M10 Bolt

ETL INDUSTRIES 4" Narrow Band Exhaust Clamp is a heavy-duty, T-304 stainless steel 4-inch ID clamp sold as a 2-piece set for secure, non-welded exhaust connections.

This two-pack of narrow band exhaust clamps from ETL INDUSTRIES is engineered to join 4" OD-to-ID slip-fit pipes, mufflers, or catalytic converter tubing without welding. Each clamp uses a 1.22" (31mm) wide strap made from premium T-304 stainless steel for corrosion resistance and long service life, paired with a zinc-plated M10 bolt and nut for reliable fastening. The design minimizes pipe distortion while delivering high clamping force, and the pre-attached hardware speeds installation or removal for maintenance and repairs.

How does this clamp make exhaust repairs faster?

Because the clamp arrives ready to fit, you can join exhaust components without welding, cutting, or special tools. Pre-attached hardware and a simple nut-and-bolt mechanism let two people or one technician secure pipes in minutes.

• Pre-attached M10 bolt and nut for quick tightening
• No-weld design reduces shop time and equipment needs
• Slip-fit compatibility with standard 4" OD-ID pipe connections
• Removable for future maintenance or part replacement

Will this clamp resist rust and road salt?

Yes — the clamp strap is made from T-304 stainless steel, which offers strong corrosion resistance in automotive exhaust environments. The bolt is zinc-plated to further reduce corrosion risk where dissimilar metals meet.

• T-304 stainless steel strap for long-term corrosion resistance
• Zinc-plated M10 bolt and nut to resist surface oxidation
• Steel gasket and aluminum alloy I-block designed for durable sealing
• Suitable for typical road and weather exposure conditions

Does the clamp damage or deform exhaust pipes?

No — the narrow-band profile and gasket system are designed to seal without crushing the pipe. High clamping loads are distributed so you get a tight connection while preserving pipe geometry for easy future removal.

• 1.22" (31mm) strap width reduces local distortion
• Approx. 1.89mm strap thickness for strength without excessive compression
• Steel gasket cushions contact and improves sealing
• High clamping force with minimal pipe deformation

What fits and where can I use these clamps?

These clamps are made for 4" ID exhaust connections and work well with mufflers, tailpipes, mid-pipes, and some catalytic converter joints. They are a practical option for repair shops, DIYers, and fabricators needing a removable, strong joint.

• Designed for 4" ID / slip-fit exhaust pipe connections
• Common uses: muffler repair, tailpipe attachment, mid-pipe joins
• Works for both temporary fixes and permanent non-welded installs
• Sold as a convenient 2-piece pack for paired connections

Who is this for? This ETL INDUSTRIES 4" narrow band exhaust clamp 2-pack is aimed at mechanics, custom fabricators, and hands-on vehicle owners who want a durable, corrosion-resistant clamp that saves time by avoiding welding. If you need a removable, high-clamp joint for standard 4" exhaust tubing — whether for repair, maintenance, or custom exhaust builds — this stainless-steel clamp gives a strong seal with minimal pipe distortion and easy installation.
