Viega 90855 – Frequently Asked Questions
1) What pipe size does the Viega MegaPress 90855 coupling fit?
The Viega 90855 MegaPress coupling is a 1-1/4 inch x 1-1/4 inch fitting, with press connections on both ends (P1 x P2). It joins two runs of 1-1/4 inch pipe in line.
2) What does "no stop" mean on this MegaPress coupling, and when would I want it?
A no-stop coupling has no internal shoulder, so it slides freely along the pipe. That is what you want on a repair or a tie-in where you cannot spring the pipe apart: slide the Viega 90855 fully onto one side, bring the second length in, then center it and press both ends. For new work where you can set the pipe into the fitting, a stop coupling is easier because the stop sets insertion depth for you.
3) Is the 90855 MegaPress fitting stainless or carbon steel, and can I use it outdoors or in a wet area?
It is 316 stainless steel, the more corrosion-resistant of the two common stainless grades, so it holds up better than carbon steel in damp, coastal, or washdown environments. Note that stainless MegaPress fittings are intended for stainless steel pipe, not for black iron.
4) How much room do I need around the pipe to press a 1-1/4 inch MegaPress coupling?
The fitting body itself measures 4.429 inches long and 2.205 inches across, so plan clearance for that plus the press jaw swing on each end. In tight chases or against a wall, the no-stop design helps because you can slide the coupling clear of the joint while you set the second pipe length.
5) What is Smart Connect on Viega MegaPress and why does it matter for inspection?
Smart Connect is Viega's feature that intentionally leaks at an unpressed connection during pressure testing, so an unpressed joint shows itself before the system is buttoned up and the walls close. On a large repipe with dozens of 1-1/4 inch joints, that is how you find the one you missed.
6) Where is the Viega 90855 coupling made?
It is made in Germany. For public and institutional work where country of origin has to be documented on the submittal, that is the value to carry through.
