Viega 25721 – Frequently Asked Questions
1) What size pipe does the Viega MegaPressG 25721 union fit?
The MegaPressG union, model 25721, is a 1-1/2 inch by 1-1/2 inch fitting with press connections on both ends (P1 x P2). It joins two runs of 1-1/2 inch black iron pipe without threading or welding.
2) Is the Viega 25721 union press on both ends or does one side thread?
Both ends press. The connection type is P1 x P2, so there is no threaded side, which means you need press pipe on both sides of the joint. If you need to transition to a threaded nipple or valve, you want a press-by-FPT or press-by-MPT adapter instead of this union.
3) What material is the Viega MegaPressG 25721 made of, and will it work on black iron gas pipe?
It is carbon steel, which is why it mates with carbon steel (black iron) pipe rather than copper or stainless. MegaPressG fittings are the gas-rated line in Viega's press system and carry Smart Connect technology, the feature that leaves an unpressed connection visibly leaking during test so you can find a joint you missed.
4) How much clearance do I need to install a 1-1/2 inch MegaPressG union in a tight chase?
The fitting itself measures 6.638 inches long, 2.992 inches wide and 2.756 inches high, so plan on that envelope plus room to get the press jaw and ring around the pipe. In a stud bay or a crowded mechanical chase, the jaw swing is usually the limiting factor, not the fitting.
5) Do I need a special press tool for a 1-1/2 inch MegaPressG fitting?
Yes. At 1-1/2 inch this is in the large-diameter MegaPress range, which is pressed with a press ring and actuator rather than a standard jaw. You will need the ring and actuator sized for 1-1/2 inch carbon steel on a compatible press tool. The fitting itself includes nothing beyond the sealing element already installed.
6) Is this union a substitute for a threaded ground joint union on gas pipe?
Functionally it does the same job, giving you a serviceable break in a 1-1/2 inch line, but it is not interchangeable at the pipe ends. A ground joint union threads on; the 25721 presses on, so the pipe ends must be cut square and deburred, not threaded. If you are tying into existing threaded pipe you will need a press-to-thread adapter at the transition.
