Viega 20838 – Frequently Asked Questions
1) What kind of connection does the Viega 20838 ProPress adapter make on each end?
The 20838 is a press-by-male-thread adapter: one end is a 4 inch ProPress copper socket that gets crimped onto 4 inch copper tube, the other is 4 inch male pipe thread that screws into a female threaded port. That makes it the transition piece when you are running pressed copper into valves, pumps, or flanged equipment with female NPT.
2) Can I use the 20838 to connect 4 inch copper to a female threaded valve?
Yes, that is exactly what it is for. The male pipe thread end threads directly into a 4 inch female NPT port on a valve or piece of equipment, and the press end takes the 4 inch copper tube. Use thread sealant or tape on the MPT side as you normally would; the press side needs no sealant.
3) Is the Viega 20838 adapter actually copper, or is it bronze?
Copper. The 20838 is listed as a copper ProPress fitting, so it is a match for a copper tube system and presses with the same jaws you use on the rest of the copper line.
4) What does Smart Connect on this Viega ProPress 4 inch adapter do for me on the job?
Smart Connect is Viega's unpressed-connection feature. If a fitting gets missed during pressing, the joint leaks visibly during pressure test rather than holding and failing later, so you can find the skipped press on a big 4 inch run before the wall closes up. The 20838 carries it.
5) Is the Viega 20838 made in the USA?
No. The 20838 ProPress adapter is made in Germany. That matters if you are bidding a job with domestic sourcing requirements, so check the spec before you submit it.
