The Hub’s patent-pending design turns one port into five. Eliminate the need to build elaborate assemblies of elbows, crosses and T’s just because there is only one port on your machine. The Hub provides two lateral 1” NPT ports, two lateral ¾” NPT ports, and one central ¼” NPT port that is designed primarily for a sampling valve. The central port is shielded to protect the sampling valve from accidental impacts and debris. The lateral ports can be used to attach drain valves, quick connects, filter carts, bowls, columns and sight glasses. The Hub is adjustable every 45° so an optimal orientation can be achieved during installation. The Hub is best used in conjunction with Luneta’s Column and Bowl. The Hub ships with a sampling valve, stainless steel pilot tube and four steel plugs to seal any unused ports.
