Information
Galvanized cast iron fittings are widely used across many industrial sectors and in central heating installations. Their main advantages are competitive pricing and wide availability. They are suitable for installations with moderate operating requirements, including cold and hot water systems.
The fittings are manufactured from malleable cast iron and protected with a hot-dip galvanized coating, providing excellent resistance to corrosion and weather conditions.
- Maximum working pressure: 25 bar at operating temperatures from -20°C to +120°C
- Maximum working pressure: 20–25 bar at operating temperatures from -20°C to +300°C
- Manufactured according to EN 10242
The hot-dip galvanized surface protects the fitting against corrosion and atmospheric conditions.
Galvanized cast iron fittings feature R taper external threads and Rp parallel internal threads, manufactured in accordance with ISO 7/1.
Each fitting is permanently marked with its size.
Available sizes: 1/8'', 1/4'', 3/8'', 1/2'', 3/4'', 1'', 1 1/4'', 1 1/2'', 2'', 2 1/2'', 3'', and 4''.
