The Oetiker PG159 CV Boot Clamps are essential components for automotive technicians and DIY mechanics looking for a reliable, permanent fastening solution for CV boots. These clamps offer a broad 40-110mm size range, ensuring a secure fit on various drive axle configurations while providing visible evidence of a proper seal upon installation. While these clamps are highly effective at maintaining a tight grip under demanding conditions, it is important to note that they require a specialized ear-clamping tool for proper installation and are intended for single-use applications.

No, these are permanent clamps designed for single-use only. Once the ear is deformed for installation, it cannot be safely reused.
Yes, you need a CV boot ear-clamp pliers or a dedicated ear-clamping tool to properly crimp the ear.
Yes, the metal construction is designed to withstand typical automotive under-car temperatures and rotational heat.
This clamp is designed for applications ranging from 40mm to 110mm.
You can confirm a correct installation by observing the deformation of the clamp's ear. If it is pinched as designed, it is secured.
Ensure the clamping tool was fully compressed to deform the ear. If the ear is not sufficiently deformed, the clamp will not provide the required radial pressure.
This may occur if the tool is misaligned or if excessive force is applied. Always use a proper ratcheting or manual ear-clamp tool and ensure the clamp is positioned squarely in the groove.
Verify that the clamp is placed directly over the seating groove of the CV boot. If the boot is torn or the groove is damaged, replace the boot before installing a new clamp.
To install these clamps, slide the clamp over the CV boot and position it within the designated groove. Use a dedicated CV boot ear-clamping tool to squeeze the 'ear' of the clamp until it reaches the desired closure point. The clamp is properly secured when the ear deformation is visible, indicating that the clamp has achieved its maximum grip. Because these are permanent fastening components, they are not designed for removal and re-installation; if a mistake occurs during installation, the clamp must be discarded and replaced with a new one to ensure the integrity of the CV joint seal.
