Why Use A V-Band Clamp?

A V-band clamp is one of the cleanest ways to join two sections of performance pipework when you need the joint to be strong, compact and easy to remove. Traditional two-bolt or three-bolt flanges rely on bolts and a gasket. That can work, but on turbo and exhaust systems, it often means seized bolts, awkward access and gaskets that need replacing when the joint is disturbed.

Our self-aligning V-band kit uses a male flange and a female flange. Once the flanges are welded to your pipework, they locate into each other, and the clamp locks them together. This gives you a secure seal without needing a separate gasket, which is ideal for downpipes, removable exhaust sections, turbo setups and fabrication work where access matters.

This is especially useful on cars that are worked on regularly. If you remove a downpipe, B-pipe, turbo outlet, screamer pipe or exhaust section for servicing, track use or future changes, a V-band joint makes that job far easier than fighting rusty hardware in a tight space. If the joint is close to a turbo or exhaust housing, it is also worth managing nearby heat with an Exoracing turbo blanket, Exoracing exhaust wrap or Exoracing heat reflective tape.

Which V-Band Clamp Size Do I Need?

Match the flange bore size to the pipework size you are using. Before welding, offer the flange up to the pipe and check that the bore and pipe line up cleanly so the joint does not create a step or restriction inside the pipework.

Exoracing V-Band Clamp Installation Guide:

Although V-band clamps are simple once fitted, correct welding and alignment matter. If you are not confident fabricating stainless pipework, ask a professional fabricator to install the clamp kit.

1. Choose the correct flange bore size for the pipework you are using. Offer the flange up to the pipe and check that the bore lines up cleanly.
2. Make sure both pipes are stainless steel, clean, dry and free from rust, oil or other contaminants before welding.
3. Weld the male V-band flange to one side of the pipework and the female V-band flange to the other side.
4. Allow the welds to cool, then bring both flanges together and check that the male and female profiles locate properly.
5. Place the V-band clamp over both flanges and make sure the clamp sits evenly around the full joint.
6. Tighten the locking nut while checking the clamp orientation. Make sure the nut does not rub against nearby components, heat shielding, bodywork or pipework.
7. After the first heat cycle, visually inspect the joint and recheck the clamp if required.

Frequently Asked Questions

Do V-band clamps need a gasket?

No. Once the male and female flanges are welded correctly, the flanges locate into each other, and the clamp holds the joint together without a separate gasket.

How do I choose the correct size?

Choose the flange bore size that matches the pipework size you are building around. If you are unsure, measure the pipe and check the bore before welding.

Can I use this on mild steel pipework?

This kit is made from 304 stainless steel and is intended for stainless fabrication work. Make sure the material is suitable for your application before welding.

Is this suitable for turbo downpipes?

Yes. V-band clamps are commonly used on turbo downpipes and exhaust sections because they make removal and refitting far easier than traditional bolted flanges.

Does the kit include both flanges?

Yes. Each kit includes the V-band clamp, male flange, female flange and locking nut.

Notes:

• Professional installation is recommended.
• Confirm the pipework size before ordering.
• Check clamp clearance before final welding so the locking nut does not touch nearby components.
• For high-heat areas, protect nearby wiring, hoses and painted panels with suitable heat management products.
