Nickson 4" Stainless Steel Flat Band Clamp, E40ST

Nickson 4" Stainless Steel Flat Band Clamp, E40ST

The Nickson E40ST is a 4-inch flat band exhaust clamp made from 304 stainless steel for heavy-duty, performance and under-car exhaust work. It's a popular choice for aftermarket Duramax and diesel exhaust installs. An aluminum reaction block creates a complete inner-circle seal when the clamp is tightened, and high-strength plated Grade 8 fasteners hold it in place. Unlike a U-bolt clamp, the flat band wraps the joint evenly, so the pipe isn't crushed and the exhaust can be taken apart later.

Key Features

• Nickson E40ST flat band clamp for 4-inch exhaust
• Bright, rustproof 304 stainless steel band
• Aluminum reaction block for a complete inner-circle seal
• High-strength plated Grade 8 fasteners
• Allows the exhaust system to be taken apart

Benefits

Crushed pipe from a U-bolt clamp makes every future exhaust job harder and often means cutting pipe to get it apart. A stainless flat band clamp seals the joint evenly, resists rust and comes back off cleanly when it's time to swap a component.

Frequently Asked Questions

What size exhaust does this fit?
It's made for 4-inch exhaust tubing.

How tight should I make it?
Tighten it evenly until the joint seals. Don't overtighten, because excessive torque can distort the pipe.

Can I reuse it?
Because it doesn't crush the pipe when installed correctly, the joint can be taken apart and reclamped. Replace the clamp if the band or hardware is damaged.

Fitment

Universal fit for 4-inch exhaust systems, including aftermarket exhausts on Chevrolet Silverado and GMC Sierra HD trucks with the 6.6L Duramax. Confirm your exhaust tubing is 4 inches before ordering.
