Never seen one - but does anyone know of a metal male threaded connector that could be used for PVC????

Since RMC and PVC have roughly the same OD would it be compliant to use a treadless RMC connector on PVC????

Reason: I hate going from PVC to Male PVC to Male threadless via a threaded coupling.... Or same sans the threadless to RMC. I always have to use metal conduit to exit concrete here due to local codes. Also plastic threaded fittings are more brittle than the conduit itself and have a tendancy to shear off when a guy stumbling around in a form mashes my conduit, usually in Wellies and a hose full of concrete...
 
I'll ask the obvious question: Why aren't you using FA's and threaded conduit? No threader on hand?

Seems like if they break your pvc off, it's usually at the FA,:roll: all it takes is another FA, piece of pvc, and a pvc coup to fix. You're using 3 fittings in the place of one FA. I'm sure I'm just not understanding your situation though...:confused:
 
What about a longer peace of RMC past the 90 and a load of sand to cushion the transition and stabilize the transition.
And no I haven't seen a steel PVC connector.

Didn't chuck the females into the equation - but same deal - shear right off... and a threader would be a long walk out of the the form most often. (Sometimes even a short one is a long one sometimes)

Anyway - since I must exit the concrete in RMC (Due to local code) - I usually cut a few sticks in 1/2 - then chuck those in the general area where they'll go. The threaded end goes up, or out. The cut end goes to the PVC. When I get to whatever point and the stick won't get through the rebar - just bend it a bit out there or lop some off. No walking back out (or in this case up a hill as well) to go thread a new piece. Not mention if you do need to un-thread it at any point for a change (And there are many on this particular Architechual fiasco) you may as well bring a hack saw or snap it yourself.

Anyway my point is that PVC fittings dont hold up to the abuse once in the form - and that abuse is usually happening while the pump is running. The conduit holds up fine - to include the coupling formed on the end - just the fittings dont.

Good luck collecting that bill. They will just say the conduit was not adequately supported and it was up to you to brace it better.

I allways complete the loop so if I lose a pipe I can get to it from the other side. Or use carflex it is not brittle like rigid pvc.

Even if you got 50-50 out of them it is still a loss and not correctable - and really once the conctrete is flowing and you're looking for footing - I can blame them personally.

But I do think there would be few brakes if there were a more maluable transition of the RMC to RNC and IMO the pvc fitting are the most brittle part and weak link.

The best survivers so far is to get that transition below a bar - which offers some good protection.

FYI Just to cut that avenue down - I will NEVER EVER use smurf EVER AGAIN....

About PVC fittings or smurf? Both end up in tears - figuratively.... And both end up unsable if broken in a pour.

I was force to use smurf by a company I worked with several years ago.

One rule to live by is NEVER use smurf in a self-leveling or high slump mix - the fittings leak in thinner concrete if the conduit doesn't get a crack and get the same -a puddle of concrete mid-run and you end up with surface mounted conduit... Next rule - never use smurf in the winter - even more brittle that it normally is.

PVC is great in sizes of 3/4" and larger, just the fittings in 1" and smaller are not the most resilient items when you have gorillas as concrete crews and it is a rare find to come across someone doing concrete who could care less about you and your silly conduit. Today had one snap from guys walking on the PVC when they miss the rebar - luckily the GC was watching and got me down to fix it. But then watched them as they nearly broke a few more by standing on the fittings at the transition between RMC and PVC. It is particulary vunrable right there.
