Watts 3518B-14 – Frequently Asked Questions
1) Can I use the Watts 3518B-14 elbow on a hot water line?
Yes, within limits. The elbow is rated to 180 F (82 C) maximum and 250 psi (17.2 bar) maximum working pressure, which covers normal domestic hot water distribution. Its stated minimum working temperature is 75 F (24 C), so it is not a fitting to specify for cold outdoor or unheated-space runs.
2) Is the Watts 3518B-14 approved for gas lines?
No. The 3518B-14 is not suitable for gas service. It is a potable water fitting only, and it is lead free, so use it for domestic water and pick a listed gas fitting for any fuel gas work.
3) Does this Watts quick-connect elbow need crimp rings or special tools to install?
No crimp ring, no solder, no glue. Both ends of the 3518B-14 are push-fit (quick connect inlet, push outlet), so a clean, square, deburred 3/4 inch tube end pushes straight in. That is the main reason crews use it in tight repair spots where a torch is not an option.
4) Will the 250 psi rating on this Watts elbow hold up on a commercial riser?
250 psi (17.2 bar) maximum working pressure is well above typical building supply pressure, which is usually regulated to 80 psi or less by code. Where it needs watching is temperature, not pressure: the ceiling is 180 F, so it is not a fitting for boiler or high-temperature hydronic service.
