1" Copper Valved Manifolds (type "L" copper) feature 1/2" crimp outlets. A soldered valve connection allows for simple and easy isolation of individual loops. Sections can sweat together to extend the number of outlets using a standard 1-inch copper coupling. Do not exceed accepted flow rates for 1-inch nominal copper. Both 1-inch ends are copper pipe size and will require a copper end cap, coupling or transition fitting to make the proper system connection. Clamp or crimp Tool is required. PEX Clamps or Crimp Rings must be purchased separately.
