Nibco M060000 – Frequently Asked Questions
1) What does a Nibco 4707-3-5 CPVC drop ear elbow connect to on each end?
One end is a female CPVC socket for solvent cement, the other is female NPT thread. So the socket side takes CPVC CTS (copper tube size) pipe cemented in, and the threaded side accepts a male NPT nipple or a threaded fixture stub. It is a 90 degree (quarter bend) elbow, so it changes direction at the same point it transitions from cemented pipe to thread.
2) Will a Nibco 4707 drop ear elbow work for mounting a shower head or hose bibb stub-out?
That is what the drop ear is for. The ear (with washer) lets you screw the fitting to blocking or a bracket inside the wall so the threaded outlet stays put when someone torques a shower arm, tub spout, or hose bibb into it. Without the ear, the stub-out moves every time the fixture is turned. Pipe side is 1/2 inch CPVC CTS socket, outlet is 1/2 inch female NPT.
3) Can I use a CPVC drop ear elbow on a hot water line?
Yes, on hot and cold potable water. CPVC carries a maximum service temperature of 180 degrees F, which covers domestic hot water distribution well above where PVC gives out. What it must not be used on is compressed air or any other gas.
4) Is the Nibco 4707 CPVC elbow lead-free and approved for drinking water?
It is a lead-free fitting and NSF U.P. Certified for potable use, which is what a facility or institutional spec normally calls for on domestic water. It is listed for both commercial and residential plumbing systems.
5) What size does the Nibco 4707 drop ear elbow come in?
1/2 inch, sold under MPN M060000. That is the size for a typical shower arm, tub spout or lavatory stub-out on a CPVC CTS system, and it is the same 1/2 inch on both the socket and the NPT thread since it is a straight size elbow.
6) Do I need to thread a CPVC drop ear elbow with tape or dope, or can I solvent cement both ends?
Only the socket end gets solvent cement. The NPT side is a threaded joint and has to be made up as a thread, not glued, because it is the female NPT half of an S x F fitting. Nibco publishes plastic fittings installation instructions covering the cementing procedure, and their technical data sheets carry the engineering detail.
7) Will CPVC corrode in a hard water or aggressive water building?
CPVC will not rust, pit, scale or corrode, which is the usual reason property managers and MRO buyers move off metallic pipe in a building with aggressive water. The material also handles hot corrosive liquids, not just potable water.
