Watts 3518B-10 – Frequently Asked Questions
1) Can I use this Watts push-fit elbow on a hot water line?
Yes. The 3518B-10 is rated to 180 F (82 C) maximum working temperature, which covers domestic hot water supply. Working pressure is 250 psi (17.2 bar). Note the rated minimum temperature is 75 F (24 C), so it is not a fitting for freezing or chilled-line service.
2) Is the Watts 3518B-10 elbow approved for potable drinking water?
It is a lead free fitting, so it is intended for potable water supply lines. The body is polysulfone plastic rather than brass, which is why there is no lead content to worry about on a drinking water branch.
3) Can I use this plastic quick connect elbow on a gas line?
No. The Watts 3518B-10 is not suitable for gas service. It is a water fitting only. For a fuel gas branch you need a fitting specifically listed for gas, not this polysulfone push-fit elbow.
4) Is a polysulfone push elbow a good choice instead of a brass or copper sweat elbow?
Polysulfone makes sense where you want no torch work and no corrosion path: the push and quick connect ends go together dry, and the plastic body will not pit or scale like metal in aggressive water. Trade-offs are the 250 psi and 180 F ceilings and the 75 F minimum rating, and it is water only, not gas. If your branch sees steam, higher temperature, or needs a threaded metal takeoff, use a metal fitting instead.
