Exoracing T-Bolt Clamp Silicone Hose Coupler

Which T Bolt Clamp Size Should I Choose?

Measure the outside diameter of the silicone hose while it is fitted over the pipe. Then choose the clamp range that covers your measured diameter.

For example, if your fitted hose outside diameter measures 70mm, choose the 2.5-inch clamp with a 67 to 75mm clamp range.

Why Should You Use An Exoracing T-Bolt Clamp?

Boost leaks and silicone couplers blowing off are common problems on turbocharged and supercharged cars. A weak, damaged or poorly fitting clamp can allow the hose to move under pressure, especially when the pipework gets hot, or the engine moves under load.

The Exoracing T Bolt Clamp uses a 304 stainless steel band and locking nut to give a strong, secure clamp around silicone hose couplers. This helps keep intake, intercooler and boost pipework sealed properly.

This matters because a loose coupler can cause boost leaks, poor performance, unstable running and frustrating fault finding. If you are fitting intercooler pipework, replacing old clips, upgrading boost pipes or building a turbo setup, T-bolt clamps are a simple way to improve reliability.

These clamps are also suitable for a range of non-automotive uses where a strong stainless clamp is required.

T Bolt Clamp Vs Standard Hose Clip

A standard worm drive hose clip can work on low-pressure jobs, but it can struggle on boosted silicone hose couplers where pressure, heat cycles and vibration try to push the hose off the pipe.

A T bolt clamp gives a stronger and more even clamping force, making it better suited to turbo, supercharged and high boost intake pipework.

• Use a T bolt clamp when: the hose is part of a boosted intake, intercooler or turbo pipe setup.
• Use a standard hose clip when the job is low-pressure and does not need a heavy clamping force.
• Best practice: Use T-bolt clamps on beaded pipe ends where possible to reduce the chance of hoses blowing off.

Installation Guide:

Correct sizing and careful tightening are the two most important parts of fitting a T-bolt clamp.

1. Fit the silicone hose coupler fully over the pipe.
2. Measure the outside diameter of the fitted hose where the clamp will sit.
3. Choose the clamp size range that covers your measured diameter.
4. Place the clamp behind the bead on the pipe where possible.
5. Tighten the clamp evenly until the hose is secure.
6. Do not overtighten, as this can damage the hose or strip the thread.
7. Recheck the clamp after the first heat cycle or test drive.

Installation difficulty: simple DIY for accessible intake and intercooler pipework. Professional installation is recommended if you are unsure or if the clamp is being used on critical pipework.

Frequently Asked Questions

How do I choose the correct T-bolt clamp size?

Measure the outside diameter of the silicone hose once it is fitted over the pipe. Then choose the clamp size range that includes your measurement.

Should I choose by pipe size or hose outside diameter?

Choose by the outside diameter of the fitted hose, not just the pipe size. Silicone hose wall thickness changes the outside diameter, so the clamp must fit over the complete hose and pipe joint.

Are these sold individually or as a pair?

Each purchase includes 1 x Exoracing T-bolt clamp. If you need to secure both ends of a silicone coupler, order 2 clamps.

Are T-bolt clamps better than standard hose clips?

For boosted intake, turbo and intercooler pipework, T-bolt clamps are usually the better choice because they provide a stronger and more even clamping force.

Can I use these on intercooler pipework?

Yes. These clamps are designed for silicone hose couplers used on intake, boost, turbo and intercooler pipework.

Do I need beaded pipe ends?

Beaded pipe ends are strongly recommended on boost pipework because they help stop the silicone hose from sliding off under pressure.

Can I use these on non-automotive applications?

Yes. These clamps can be used for a wide range of applications where the size range, temperature range and stainless steel construction are suitable.

Notes:

• Measure the outside diameter of the hose once fitted over the pipe before choosing a clamp.
• Do not choose by pipe size alone, as silicone hose wall thickness varies between brands.
• Each purchase includes 1 clamp. Order 2 clamps if securing both ends of a coupler.
• Do not overtighten, as this can strip the thread or damage the hose.
• Beaded pipe ends are strongly recommended on boost pipework.
• Professional installation is recommended if you are not confident.
