Viega 25231 – Frequently Asked Questions
1) Can I use a MegaPressG carbon steel elbow on a gas line?
MegaPressG is Viega's gas-rated press system, and the 25231 is a MegaPressG 45 degree elbow in carbon steel for 1/2 inch pipe. It's built for black iron gas piping rather than the plain MegaPress water fittings, which use a different sealing element. Make sure the fitting you are pressing is the G version (yellow marking on the sealing element) and that the jaw and tool match the system.
2) Will this Viega elbow work on copper or stainless pipe?
No. The 25231 is a carbon steel fitting, sized for 1/2 inch carbon steel (black iron) pipe. Copper takes Viega's ProPress copper fittings and stainless takes the stainless line. Mixing a carbon steel press fitting onto copper tube is not a valid joint, the tube OD and the sealing element are both wrong for it.
3) What does Smart Connect on the Viega 25231 actually do for me during pressure test?
Smart Connect is a deliberate leak path built into the fitting. If a joint gets missed and never pressed, the unpressed connection leaks visibly during pressure testing instead of holding temporarily and failing later behind a wall. On a long gas or mechanical run with dozens of 45 degree turns, it's what lets one test find the joint you skipped.
4) How much space do I need to fit the Viega 25231 elbow in a tight joist bay?
The fitting measures 3.295 inches long, 2.252 inches wide and 1.264 inches high. Plan for more than that in practice: a MegaPress jaw needs clearance around the fitting body to close on the press ring, so allow working room on both ends, not just the fitting footprint.
5) Do I need to order anything else with the 25231 elbow to make the joint?
The sealing element comes in the fitting, so the elbow itself is complete. What you supply is the tool: a press tool with the correct MegaPress jaw or ring for 1/2 inch, plus a depth marker and a pipe cutter and deburring tool. Pipe ends have to be cut square, deburred, and marked to insertion depth before pressing, or the seal will not seat properly.
6) Is the Viega 25231 made in the US or imported?
Made in Germany. That matters on public and institutional jobs with domestic sourcing requirements, so check the spec on the drawing before you standardize a gas retrofit around MegaPressG carbon steel fittings.
7) How heavy is a 1/2 inch MegaPressG 45 elbow for takeoff and shipping counts?
Each 25231 elbow weighs 0.309 lbs. On a large bid, that's a hair under a pound for every three fittings, useful if you're pricing freight on a several-hundred-piece pull for a multi-family gas repipe.
