Multi-diameter coupling with high angular deflection (10°)
Wide-tolerance multi-diameter coupling, made of GGG-50 ductile iron, for connecting rigid pipes of different materials. Its standout feature is an exceptional angular deflection of up to 10°, which makes assembly easier in difficult conditions.

The GA03-2 multi-diameter coupling is designed to offer maximum flexibility on site. While it shares the ability to join pipes of various materials (steel, cast iron, PVC, asbestos cement, etc.) securely and watertight thanks to its wide tolerance range, its real competitive advantage is the ability to accommodate an angular deflection of up to 10°.
This enormous flexibility makes it the perfect item for repairs or installations in imperfect trenches, on unstable ground or where pipes are not perfectly aligned. It "forgives" imperfections in the alignment, reducing the need for precise cuts and the mechanical stress on the pipe, which extends the service life of the whole installation.
Built with a robust body and glands of GGG-50 ductile iron and a high-quality EPDM gasket, this coupling guarantees a durable, reliable solution for the most challenging connection scenarios, where other rigid couplings simply would not work.
- Body and glands
- GGG-50 ductile iron with epoxy coating.
- Sealing gasket
- Wide-range EPDM rubber.
- Bolts
- Zinc-plated steel with chrome-nickel treatment for greater corrosion resistance.
- Standout feature
- Accommodates an angular deflection of up to 10°.
- Nominal pressure (PN)
- 16 bar.
- Universal compatibility
- Suitable for any type of rigid pipe.
- Assembly type
- Non-restrained. Requires external anchoring to control the axial forces of the network.

- Installations with misalignmentIts main use is in trenches or routes where pipes cannot be perfectly aligned.
- Repairs on unstable groundAbsorbs ground movement and settlement that could damage rigid joints.
- Joining pipes of different stiffnessEases the transition between materials by allowing a certain degree of "play".
- Fewer bends and special fittingsIn some cases, its deflection capacity can avoid the use of small-angle bends.
- Maintenance of old networksAn indispensable tool for maintenance crews facing unpredictable working conditions.
