The 90 mm x 1 1/2" ductile iron collar is the ultimate professional solution for efficient water supply connections, branch lines, and repairs. Designed specifically for polyethylene (PE) and PVC pipes, this component guarantees a completely watertight, strong, and durable joint under any typical working pressure conditions found in hydraulic networks and irrigation systems.

Manufactured from high-quality ductile iron and coated with epoxy paint, this collar offers excellent resistance to corrosion, impacts, and chemical agents present in the ground or the transported fluid. Its four-bolt tightening system ensures uniform force distribution across the pipe, preventing deformation and guaranteeing a perfect, long-term seal thanks to its high-performance rubber gasket.

Features of the Iron Collar 90 mm x 1 1/2"

• Main measurement: 90 mm diameter for pipe with 1 1/2" female threaded outlet.


• Manufacturing material: Ductile cast iron with maximum mechanical strength.


• Corrosion protection: Epoxy coating applied by thermofusion that extends the useful life of the part.


• Fixing system: 4 high-strength screws for symmetrical, secure and firm tightening.


• Pipe compatibility: Suitable for polyethylene (PE) and PVC systems in drinking water, sanitation and agricultural irrigation networks.


• Guaranteed leak-proof: Incorporates a sealing O-ring that prevents leaks even with pressure variations.


• Manufacturer reference: BA42107.

Frequently Asked Questions

What type of pipes is this collar compatible with?

This model is designed to be installed on high and low density polyethylene (PE) pipes as well as on polyvinyl chloride (PVC) pipes, provided that the outside diameter of 90 mm matches.

Can it be used in drinking water installations?

Yes, the materials and epoxy coating with which it is manufactured comply with current health regulations for contact with water intended for human consumption, making it completely safe for municipal supply networks.

What advantage does the 4-screw system offer compared to other models?

The use of four screws allows the tightening pressure to be distributed much more evenly around the entire circumference of the tube, drastically reducing the risk of leaks due to uneven tightening and providing greater structural stability to the assembly.

Is it necessary to use Teflon tape or other sealant on the 1 1/2" thread?

Yes, to ensure a completely watertight hydraulic connection at the 1 1/2 inch threaded outlet, it is recommended to use PTFE (Teflon) tape or approved sealing paste depending on the type of threaded fitting to be connected.
