Alternative Name
Reducing Coupling 4" × 3" Galvanized Malleable Iron, Galvanized Reducing Coupling, Female Thread Reducer, Cast Iron Reducing Coupling, BSP Female Adapter, Water Pipe Coupling
Information
The 4" × 3" galvanized reducing coupling is manufactured from malleable iron and is designed for reducing threaded pipe connections in water, heating, and industrial installations. It features female threads on both ends, providing a durable and reliable threaded connection.
Galvanized malleable iron fittings are widely used in industrial applications thanks to their durability, competitive cost, and excellent availability. They are suitable for installations with moderate operating requirements, including cold and hot water systems.
Material
The fitting is manufactured from malleable iron and protected with a hot-dip galvanized coating, which provides effective resistance against corrosion and atmospheric conditions.
Technical Specifications
- 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 fitting features:
- External tapered threads: R
- Internal parallel threads: Rp
Both thread types comply with ISO 7-1.
Advantages
- Hot-dip galvanized finish
- Excellent corrosion resistance
- Female threaded connection
- Durable malleable iron construction
- Cost-effective solution
- Manufactured according to EN 10242
Applications
Hydraulic installations, industrial systems, central heating installations, cold and hot water systems, and general plumbing applications.
