Watts 0650175 1/2 Cts X 1/2 In Mpt Plastic Male Connector

The Watts 3501B series 650175 is a quick connect to male threaded adapter: 1/2 inch CTS quick connect on the inlet side, 1/2 inch NPT male thread on the outlet. The quick connect end pushes on to 1/2 inch tubing with no solder, no crimp ring and no special tool, and the threaded end screws into any 1/2 inch female NPT port. Body is polysulfone plastic with an EPDM O-ring seal.

Yes, within limits. The 650175 is rated to 180 degrees F (82 C) maximum working temperature and 250 psi maximum working pressure, which covers normal domestic hot water supply. It is not a fitting for steam or boiler service, and the data also sets a 75 degree F (24 C) minimum temperature, so don't rely on it in freezing or unheated spaces.

No. The 650175 is a water-service fitting only, and is specifically listed as not suitable for gas. For fuel gas, use a fitting rated and listed for gas service instead.

Yes. The outlet is 1/2 inch male NPT, which mates with any standard 1/2 inch female NPT or FIP port, including valve bodies and iron pipe adapters. Tape or pipe dope suited to plastic threads, and hand tighten plus a modest turn only, over-torquing a polysulfone thread is what cracks it.

All plastic. Both the inlet and outlet ends are polysulfone and the fitting carries no brass insert, so there is no dissimilar-metal contact and nothing to corrode in aggressive water. If your spec calls for a metal-reinforced threaded end, this is not the part.

Plan around a 1 1/8 inch outer diameter on the 650175 body. In tight stub-out or cabinet locations that OD is the number that decides whether the fitting clears the wall plate or neighboring line, since the push-fit end is wider than the 1/2 inch tubing it accepts.

Yes, country of origin on the 650175 is the United States, which matters if you're buying against a domestic-preference or Buy American procurement requirement on a public project.
