Viega 84795 – Frequently Asked Questions
1) What are the two ends on the Viega MegaPress 84795 adapter?
The 84795 is a P x FPT adapter: one press end for 1-1/2 inch black iron pipe and one 1-1/4 inch female pipe thread. So it presses onto the pipe on one side and takes a male-threaded nipple, valve, or fitting on the other.
2) Does the Viega 84795 MegaPress adapter reduce from 1-1/2 inch pipe down to a 1-1/4 inch thread?
It does. The press side takes 1-1/2 inch carbon steel pipe and the threaded side is 1-1/4 inch FPT, so you get the size change and the transition to threaded in one fitting instead of a press-by-thread adapter plus a reducing bushing.
3) Can I use a MegaPress carbon steel adapter on copper or stainless pipe?
No. The 84795 is a carbon steel press fitting, built for black iron and carbon steel pipe. For copper tube you need a copper or bronze press fitting, and for stainless you need a stainless press fitting with the correct sealing element. Using a carbon steel body on copper also sets up dissimilar metal contact at the joint.
4) Is press or threaded better for tying a 1-1/2 inch black iron line into a threaded valve?
Threading 1-1/2 inch pipe on site means a machine, cutting oil, and a lot of time per joint. A press adapter like the 84795 lets you press the 1-1/2 inch run and keep just the 1-1/4 inch FPT connection at the valve, which is usually the only threaded joint you actually need. Threading still wins where you cannot get a press jaw into the space, or where the pipe end is too corroded or out of round to press on.
5) Do I need to order a sealing element or gasket separately for the Viega 84795?
No separate seal to buy. MegaPress fittings ship with the sealing element already installed in the press end. You still prep the joint the normal way: cut square, deburr, mark the insertion depth, and press with the correct 1-1/2 inch jaw.
6) What does Smart Connect do on a MegaPress fitting?
Smart Connect is the feature that makes an unpressed joint leak on purpose during pressure test, so you find the connection you missed instead of discovering it after the ceiling is closed. On a large job with dozens of 1-1/2 inch joints, that is the main reason crews pick this family.
7) Where is the Viega 84795 MegaPress adapter made, and how much does it weigh?
It is made in Germany and weighs 0.886 lbs. Useful if you are submitting country-of-origin documentation on a government or institutional job, or figuring hanger spacing on a run with several of these in it.
