Viega 84135 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 84135 coupling join?
The MegaPress 84135 is a 3/4 inch by 3/4 inch coupling, so it joins two runs of 3/4 inch pipe press to press. Both ends are press connections (P1 x P2), no threading or welding at either end.
2) What is a no-stop MegaPress coupling used for instead of a standard coupling?
A no-stop coupling has no internal tube stop, so the pipe can slide all the way through it. That lets you make a repair or a tie-in on a fixed length of pipe that can't be pulled apart, which a coupling with a center stop won't allow. The tradeoff is that you have to mark your insertion depth on both sides yourself, because nothing inside the fitting sets it for you. For new work where you can set the pipe into the fitting, a stop coupling is the easier choice.
3) Is the Viega 84135 carbon steel coupling suitable for copper or PEX?
No. It is a carbon steel fitting, made for black iron / carbon steel pipe systems such as gas, hydronic heating and fire protection piping. For copper tube you need a copper press system fitting, and for PEX a PEX press fitting. Carbon steel press fittings and copper press fittings are not interchangeable.
4) What does Smart Connect technology on a MegaPress fitting actually do for the installer?
Smart Connect is a feature of the sealing element that lets an unpressed fitting leak intentionally during the pressure test. Instead of discovering a missed joint after the system is closed up, you see it on the test, which is why the 84135 coupling is worth using on long runs where joints are easy to lose track of.
5) How much room do I need around the pipe to press a 3/4 inch MegaPress coupling?
The fitting body itself is 1.496 inches across and 2.945 inches long, so that is the envelope of the joint before you add the press jaw. Plan clearance for the press tool jaw on top of that body width when you are working tight to a wall, a joist, or a parallel run.
6) What is the Viega part number and country of manufacture for the 3/4 inch MegaPress no-stop coupling?
Order it as Viega part 84135. It is made in Germany. That is the number to quote if you are matching an existing submittal or standardizing MegaPress fittings across a building.
