Information

The 4" × 2" 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
