The 110 mm x 1 1/4" iron collar (Reference: BA43745 ) is an essential and highly reliable component specifically designed for making connections, branch lines, and repairs in drinking water and sanitation distribution networks. Manufactured from robust ductile iron , this element guarantees exceptional resistance to pressure and impacts, offering a durable and safe solution for both professional plumbing installations and civil engineering projects. Its optimized design allows for seamless integration into polyethylene (PE) and polyvinyl chloride (PVC) pipe systems, ensuring a watertight seal and minimizing the risk of leaks throughout its long service life.

This type of repair and connection clamp stands out for its epoxy paint coating, which provides superior protection against corrosion, oxidation, and chemical agents present in the soil or the transported fluid itself. The four-bolt, high-strength fixing system distributes pressure evenly around the entire circumference of the pipe, preventing deformation and ensuring a firm hold. It is the preferred choice for installers and professionals seeking quick assembly without compromising on the highest standards of quality and safety in hydraulic networks.

Frequently Asked Questions about the BA43745 Repair Collar

On what types of pipe can this collar be installed?

It is specifically designed for use in polyethylene (PE) and PVC pipes, adapting perfectly to their standard outside diameters and guaranteeing a watertight seal through its inner rubber gasket.

Is it suitable for buried installations?

Yes, thanks to its ductile iron body and high-strength epoxy coating, it perfectly withstands adverse ground conditions and humidity, making it suitable for underground installations in drinking water networks.

What advantage does the four-screw system offer?

The use of four screws allows for a much more homogeneous and secure cross-tightening compared to two-screw models, avoiding excessive stress on localized points of the pipe and ensuring greater resistance to internal pressure.

Can it be used to repair a leak in a damaged pipe?

Indeed, in addition to its main function as an element for supply and branching, it acts as an excellent repair clamp to seal cracks or small, localized breaks in water pipes.
