About the Viega 49186

The Viega 49186 is a combo ManaBloc with both 3/8" & 1/2" PEX ports and is designed for hot and cold water applications (6 hot and 7 cold - 3/8" PEX, 2 hot and 3 cold - 1/2" PEX).  It features modular ManaBloc sections for added versatility and is made of polysulfone plastic which is highly resistant to hot temperatures and chemicals that are commonly found in potable water systems. Corrosion-resistant metals provide added durability and lengthen the ManaBloc's service life without the need for constant part replacement. 

This Viega ManaBloc uses 1/2" and 3/8" PEX press connections for quick and easy installation and is also designed to be used with the ViegaPEX Ultra and Viega FostaPEX tubing and connection for optimal performance.  It is lead-free for potable water use and is designed with a max pressure rating of 100 PSI at 180 degrees Fahrenheit. The port or branch has a pressure drop of 3.4 PSI at 4.0 GPM for the 1/2" PEX and 2 PSI at 2.5 GPM for the 3/8". This ManaBloc is designed for both home and commercial applications and is ideal for zoning multiple outlets for added safety and efficiency.
