Watts 3545-10 R – Frequently Asked Questions
1) What size and type of tubing does the Watts 3545-10 R quick-connect cap fit?
The 3545-10 R is a 1/2 inch CTS quick-connect end cap. It pushes onto 1/2 inch copper tube size pipe, and the tube support and collet clip needed to make the joint come with it, so nothing extra is required to cap a line.
2) Can I use the Watts 3545-10 R cap on a hot water line?
Yes. The cap is rated to 180 F (82 C) at a maximum working pressure of 100 psi (6.9 bar), which covers domestic hot water. Its low end is 33 F (0.56 C), so it is not for lines that may freeze.
3) Is the Watts 3545-10 R approved for gas lines?
No. The 3545-10 R end cap is not suitable for gas service. Use it on water only; a gas stub needs a cap listed for fuel gas.
4) Is this Watts push-fit cap lead free for potable water?
It is a lead free fitting, and the body is polysulfone plastic rather than brass, so there is no lead-bearing alloy in the wetted path. That makes it usable on potable water lines.
5) I need to cap off a 1/2 inch stub during a unit turn. Do I need tools or solder for the 3545-10 R?
No soldering and no tools. The 3545-10 R is a push-on quick-connect cap: cut the 1/2 inch tube square, slide the supplied tube support into the pipe end, push the cap on, and set the collet clip to lock it. That makes it practical for property managers capping a line while a fixture is out.
6) Why does the Watts 3545-10 R include a tube support, and do I have to use it?
Use it. The tube support is an insert that goes inside the tube end to keep the pipe round so the O-ring seals and the grab ring bites evenly. It ships with the cap along with the collet clip, which locks the collet so the joint cannot be pushed off accidentally.
7) Will the Watts 3545-10 R hold pressure for a system test?
It will hold up to 100 psi (6.9 bar) working pressure at temperatures from 33 F to 180 F. If your test pressure exceeds 100 psi, this plastic cap is not the right part for it.
