DZR Brass pipe fittings. Can you tell the difference?

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..........

teletype - they must have been using that picture for more than 20 years.

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.

DZR is important if the stopcock is going underground, or the water company advises it.
