Viega 77747 – Frequently Asked Questions
1) What size copper tubing does the Viega 77747 ProPress cross-over fit?
The Viega 77747 cross-over is a 3/4 inch by 3/4 inch copper fitting, so it presses onto 3/4 inch copper tube on both press ends. It is a press-to-press fitting (P1 x P2 connections), not threaded or soldered.
2) What is a ProPress cross-over fitting actually used for?
A cross-over lets one 3/4 inch copper line jump over another pipe without touching it, so two runs can cross in the same plane instead of being offset with multiple elbows. The 77747 does that in a single press fitting on both ends, which saves joints in tight joist bays and mechanical rooms.
3) How much clearance does the Viega 77747 cross-over need in the pipe run?
Plan for roughly 6.299 inches of width, 2.394 inches of height and 1.248 inches of length on the 77747. The width is the dimension that matters when you are laying out the crossing run; the height is what determines whether the hump clears the pipe being crossed.
4) Does the Viega 77747 have the Smart Connect feature that shows an unpressed joint?
Yes. The 77747 is built with Viega's Smart Connect technology, which lets water or air escape at an unpressed connection during testing so the installer can find the missed joint before the system is charged. On a crossing run with several fittings in a row, that is the difference between finding the miss at test and finding it in a ceiling.
5) Is the Viega 77747 cross-over copper or bronze, and where is it made?
Copper body, made in Germany. Copper press fittings are the match for a copper potable or hydronic system; if your run is carbon steel or stainless, this is the wrong material family and you need the corresponding ProPress steel or stainless fitting instead.
6) What is the Viega part number and weight for the 3/4 inch copper ProPress cross-over?
Order it as Viega part 77747. It weighs 0.413 lbs, which is useful if you are building out a bulk order of press fittings and need shipping weight per piece.
