Cast iron fittings – general information

Cast iron fittings include mainly threaded pipe connectors used to connect threaded pipe ends in industrial pipework conveying cold and hot water, non-aggressive fluids, gas, steam and in fire protection systems. They are made of white malleable cast iron and comply with EN 10242 and ISO 49. Working pressure 25 bar (up to +120°C), 20 bar (+300°C). Normally zinc-plated, but also available black, not galvanized.

The connectors have BSP female parallel thread (Rp, ISO 7-1), BSPT male taper thread (R, ISO 7-1); pipe unions (nuts and sockets) have BSP parallel thread (G, ISO 228-1).
The tightness of the connection is achieved along the thread (BSP (Rp) female parallel thread mates with BSPT (R) male taper thread). Thread sealant must be used (PTFE thread seal tape, liquid sealant).

Other types of threaded pipe connectors made of cast iron or carbon steel are available on request.
