Watts RA-1-AP 3/4 – Frequently Asked Questions
1) What size and thread does the Watts RA-1-AP 3/4 radiator valve connect to?
The RA-1-AP 3/4 takes 3/4 inch IPS female threaded pipe on the inlet, so it threads straight onto a 3/4 inch male IPS supply nipple. The outlet is a 3/4 inch union joint, which is what lets you break the connection at the radiator without cutting pipe. Metric equivalent on the inlet is 20 mm.
2) Can I use this Watts angle valve on a low pressure steam radiator?
That is exactly what it is built for. The RA-1-AP is a radiator supply valve rated to 15 psi on steam, which covers standard low pressure one pipe and two pipe residential and small commercial steam systems. On hot water it is rated to 60 psi.
3) Is the Watts RA-1-AP lead free and can I use it on potable water?
No. The RA-1-AP is a bronze valve that is not lead free, so keep it on steam and closed loop hydronic heating only. For anything touching drinking water you need a certified lead free valve.
4) Does the Watts RA-1-AP meet Buy American Act requirements for a government job?
It does not. The RA-1-AP 3/4 is listed as not Buy American Act compliant, so if your federal or state contract carries a BAA or domestic sourcing clause, this valve will not satisfy it.
5) What is the Watts part number for the 3/4 inch RA-1-AP radiator valve?
Order it as Watts RA-1-AP 3/4, factory part number 67451. That is the 3/4 inch bronze angle radiator supply valve in the RA-1-AP series.
