i bought many koolance parts. i have many taps that rusted. not all of them though. it seems the problem is in the nickel plating. it was not properly done in all batches.also i am not sure about the d5 tops. they seem nickel plated but koolance did not 100% guarantee them.instead they told me to use a good fluid to prevent corrosion. i chose feser as it seems its very good. the 1/2 barbs are excellent. nickel plated and slimmer than ther rest. they fit perfectly to d'tek fuzion v2 and allow any type of tubing to fit well.
but this is not a thread about products. i hope to give a good example on how an opinion should be written. i think i was a 100% objective.
