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..........

Thanks.
The DR symbol referred there is something I have never seen (or noticed)
despite me having literally hundreds of brass compression fittings I
have accumulated over the years.
I guess this isn't very common.
