ECN Forum Forums General Topics of the Trade General Discussion Area US Conduit Sizes?

Rick,
Those are strange Metric sizes.
Our sizes over in NZ here are(OD)
16,20,25,32,40,50 and 60mm.
It comes in Grey Medium Duty, Orange for where Chemical Resistance is required and
Black Heavy duty for where rugged mechanical
protection is required.
We also have flexible corrugated PVC conduit,
in these sizes.
