MegaPress FKM


MegaPress FKM

Viega MegaPress FKM is the first and only clean, secure and efficient choice for joining ½" to 4" carbon steel pipe with an FKM sealing element (formerly known as MegaPress XL for sizes 2½" to 4"). Meticulously engineered, it is suitable for renovations, repairs or installation of new carbon steel pipe systems. Viega MegaPress FKM can even be installed on noncombustible/​flammable lines that are not completely shut down, eliminating the need to fully drain a system, and shortening repair and installation time. It is approved for use in hydronic heating, compressed air, fire protection, cooling water, marine applications and many more. Not approved for use with potable water.
