Viega 28775 MegaPressG coupling With stop Smart Connect technology Carbon steel, 3" x 3"

The 28775 MegaPressG coupling is a 3 inch by 3 inch carbon steel fitting, so it joins two runs of 3 inch pipe. Both ends are press connections (P1 x P2), not threaded and not grooved, so the pipe ends need to be cut square, deburred and marked for insertion depth before pressing.

MegaPressG is Viega's gas-rated press system for black iron and carbon steel pipe, which is what separates it from standard MegaPress used on non-gas lines. The 28775 is the 3 inch carbon steel coupling in that system. Always confirm the application against the authority having jurisdiction for your local fuel gas code.

The stop is an internal shoulder that sets pipe insertion depth on each side, so both pipe ends bottom out at the same point and you get a consistent press. Use a coupling with a stop for normal pipe-to-pipe joints. A stopless (slip) coupling is what you want for a repair in a fixed run, where you need to slide the coupling fully onto one pipe and back over the joint because you cannot spread the pipe apart.

Smart Connect is Viega's unpressed-connection feature: an unpressed fitting leaks visibly during pressure test so the installer can find it before the system is put into service. On a large gas or mechanical job with dozens of 3 inch joints, that is the difference between finding one missed press at test and chasing it later behind a ceiling.
