The 75 mm x 1 1/2 inch iron collar , reference BA43719, is an essential accessory for creating safe and efficient branch connections in water supply networks, agricultural irrigation systems, and sanitation installations. Made of durable ductile iron, this component is specifically designed to ensure a firm and long-lasting connection to polyethylene (PE) and polyvinyl chloride (PVC) pipes. Thanks to its high-quality system, it allows for the quick creation of a new connection or service line without interrupting the main supply.

This model's structure stands out for its epoxy coating, which provides excellent protection against corrosion, chemical agents present in the soil, and wear caused by constant water flow. Its four-bolt design ensures even pressure distribution around the pipe, preventing deformation and leaks. It is the ideal solution for both plumbing and installation professionals and homeowners seeking optimal performance in their piping systems.

Frequently Asked Questions

What type of pipes is this collar compatible with?

This collar is designed for installation on polyethylene (PE) and PVC pipes, perfectly adapting to the standard 75 mm outside diameters used in pressure networks.

Can it be installed without cutting off the water supply?

Yes, this type of fitting allows for making connections or tapping into the pipe under pressure. However, it is recommended to follow appropriate safety precautions and use specific tools to pierce the pipe once the collar is securely tightened.

What advantage does epoxy coating offer?

The epoxy coating acts as a highly effective protective barrier against corrosion and oxidation, significantly extending the product's lifespan, even when installed buried or in humid environments.

Is it resistant to the typical working pressure used in irrigation and plumbing?

Yes, being made of ductile iron and having a four-screw tightening system, it perfectly withstands the standard working pressures required in hydraulic installations and agricultural irrigation systems.
