Common Questions

Can I use a black iron F x F elbow on water pipework? It’s suited to heating systems and other closed pipework, but it isn’t the usual choice for drinking water. For mains or potable water, copper or plastic is the normal route.

Can I use this black iron elbow on natural gas? Yes, black malleable iron is a common choice for natural gas pipework and these fittings are made for gas installation. The job must be done by a Gas Safe registered engineer.

Can black iron fittings like this elbow be used outside? The black finish will rust if it’s left exposed to the weather. For outdoor runs, go for the galvanised version of the same elbow.

Can I paint black iron fittings? Yes, once they’re clean and grease free you can paint them, which also helps keep rust away. A metal primer first gives the topcoat a better grip.

Can I use this black iron elbow on compressed air? Yes, compressed air lines are one of the jobs malleable iron fittings are made for, alongside heating, gas and steam.

What thread does a black iron elbow have? The fittings use tapered threads, so the male and female threads pull up tight against each other along their full length.
