| Use case | Recommended product | Why |
|---|
| Straight connection of two pipe sections in an exposed area | FERRO SGC2 Straight Union Fitting 1/2 Inch Chromed | The chromed finish provides a clean, aesthetic appearance for visible installations. |
| Straight connection of pipes or fittings in technical areas | Brass Straight Union 1/2" FERRO SGU2 | Durable brass construction is optimal for hidden or utility spaces. |
| Navigating corners and pipeline turns | Brass angled union fitting 1/2" FERRO SGU5 | The angled design allows for compact installation in tight spaces. |
| Connecting a heating element or creating a distribution line | T-Union 1/2” FERRO T-KUS.0 | The T-shape design allows three pipe connections to merge into a single system. |
| Installing multilayer pipes without soldering | Compression coupling FERRO K5ZL15PEXAL | The specialized compression joint securely seals 16x2 mm pipes. |
| Eliminating air locks in radiators | Manual Air Vent FERRO O18Y | The key-operated cap and O-ring seal allow controlled and effective system venting. |
FERRO SGC2 Straight Union Fitting 1/2 Inch Chromed is best suited for straight connections in water supply and heating systems where an attractive finish is required due to its chromed surface. Choose it when a reliable, separable joint is needed in exposed pipe sections, whereas alternative models should be selected for angled turns, branch lines, multilayer pipe installation, or system venting.
