Viega MegaPressG with an HNBR sealing element is the first
press fitting system for carbon steel pipe approved for use in
gas and fuel oil applications. Viega MegaPressG is ideal for industrial, commercial and residential applications and performs
well in both new installations and retrofit projects. Tested to the strictest standards in North America, Viega MegaPressG joins carbon steel pipe reliably through the engineered design of the fittings and a battery-​powered press tool. Not approved for use
with potable water.
