Legend’s M-8330 stainless-steel manifold series includes three models. The premium .304 stainless-steel 1” supply header has built-in flow meters that allow for precise adjustment of the circuit flow rates. The 1” return headers have easy-to-actuate circuit-isolation valves. All components have superior EPDM O-rings and seals. Every manifold is loosely assembled onto its mounting bracket, ready for immediate installation at the jobsite. The three models are the M-8330P Stainless Steel Pro, M-8300AP Stainless Steel Pro and M-8300 Basic.
