Hello,
I see that BES sells compression fittings that are specifically described as being made from DZR brass "dezincifaction resistant". They are more expensive than standard fittings.
This is a distinction that most suppliers do not seem to make.
So the question is: Is it important or irrelevant in "normal" domestic applications?
Can you visually tell the differernce between a DZR and a non DZR fitting? Are there different BS standards marked?
I note that all compressions fittings seem to have coded markings (squares, triangles, circles, dots and sometimes text) that presumably identify the manufacturer.
Just curious..........
