Galv pipe and black iron fittings?

[Plucky]

Can these be joined on gas pipework?

Galvanised pipe yes
Black iron fittings no have to be galvanised also

 

[aceplumber]

you can use both on gas , galv really is for portable water , black iron is for gas and heating

No probs with either , youd normaly use the same fittings as tube but it does not really matter.🙂
