Applications and Common Issues Addressed

• Secures diesel particulate filters to prevent exhaust leaks
• Maintains proper alignment of exhaust components under vibration
• Prevents damage caused by loose or failing clamps in diesel exhaust systems

Installation Notes and Tips

Installation of the Dorman 674-7021 clamp requires no special tools, thanks to its manual adjustment and bolt clamping design. Ensure the clamp diameter matches the exhaust pipe size between 230 mm and 245 mm for a secure fit. Since this clamp is non-reusable, replace it with a new unit if removal is necessary. Proper torque should be applied to the bolt to avoid over-tightening, which could damage the clamp or exhaust components.
