Do you guys know if there is any difference in robroy and ocal pvc coated rigid?

Ocal is garbage thats why a lot of agencies here in NYC are sending memos to contractors to NOT use OCAL due to the fact that PVC does not adhere well to a galvanized material and it rust from inside out, in addition to that, OCAL is not made in Merica!

Interesting Giorgo. Ocal is pretty much all we use in CO. I used Rob Roy in NE years ago and I don't recall there being much difference. I would deffinately like to hear some more input.

I will get you the report that was sent out to us by a federal agency that did perform test on Ocal PVC GRC to back up their claim and I could not believe what I saw, it was pretty interesting to the extent and magnitude of the test describing each element that these conduits and fittings are exposed to. Don't believe what I am saying till I provide you with the memo sent out to us and other inspectors, revision of specs and issuing addendum for changes, so they want us to use T&B, Rob Roy but not Ocal.

I personally don't like Ocal. The coating is crap. Ever try to screw a factory thread into a condulet? One of our customers only allows Robroy. It is actually in the specs. The other option is Calbond, although I've never used any. FYI, most people are probably not installing PVC coated conduit correctly.

No one ever does it correctly unless you have an inspector watching over your shoulders at all times unless you do spot checks at random threaded connections.

Absolutely no reason not to install per manufacturers recommendations. Our jobs specs require proper install and tooling.

Price is a big difference, I know that. Ocal is cheaper. Robroy is better quite on my opinion.

I've sold both in the past and their almost identical in coating quality. My customers prefer Cal Conduits PVC coated, it's very good quality and the price is reasonable.
