Viega 28785 – Frequently Asked Questions
1) What size pipe does the Viega 28785 MegaPressG coupling join?
The Viega MegaPressG 28785 is a 2-1/2 inch by 2-1/2 inch coupling, so it joins two runs of 2-1/2 inch pipe. Both ends are press connections (P1 x P2), with no internal stop, and the body is carbon steel.
2) What does a no-stop coupling mean on a MegaPressG fitting, and when do I need one?
No stop means there is no internal shoulder inside the 28785 coupling, so the fitting can slide freely along the pipe. That is what you want for repairs and tie-ins where you cannot pull the pipe apart: slide the coupling clear, position it over the joint, mark your insertion depth on both sides, then press. A stop-type coupling butts both pipe ends against a center ridge and is the one to use on new runs where you want the insertion depth set for you.
3) Can I use the Viega 28785 carbon steel coupling on gas piping?
MegaPressG is Viega's gas-rated press system, and the 28785 is a MegaPressG carbon steel coupling in 2-1/2 inch. It is built for black iron / carbon steel gas pipe rather than potable water, which runs on the copper and stainless press lines. Confirm the application against your local gas code before pressing.
4) What is Smart Connect on this Viega press coupling and does it change how I install it?
Smart Connect is a deliberate leak path designed into the sealing element of the 28785 coupling, so an unpressed connection weeps visibly during pressure test instead of hiding until the system is in service. It does not change the install, you still clean the pipe, mark insertion depth, and press with the correct jaw for 2-1/2 inch. It just means a missed joint shows up on test.
5) How much room do I need around the pipe to fit the Viega 28785 coupling?
The 28785 measures 4.921 inches in length and 3.543 inches in both height and width, and weighs 1.728 lbs. Plan the 3.543 inch envelope around the pipe for the fitting body, plus clearance for the press ring to seat and rotate, which is the real constraint in tight joist bays and against walls.
6) Do I need thread sealant or a weld on the Viega 28785, and what part number do I order?
Neither. The 28785 is a press-to-connect coupling with sealing elements already installed, so there is no threading, no dope, and no hot work on a 2-1/2 inch carbon steel joint. Order by Viega part number 28785. It is made in Germany.
