The Protium Triple Port Reservoir Cap comes included with all Protium Reservoirs and the Protium 150 D5/Reservoir Combo. It is available separately as an add-on or replacement part to reconfigure existing products or create a custom version. The triple port cap gives you three ports at one end of your reservoir or pump and reservoir combination which can be rotated 360 degrees to face any direction in your build. This cap can be used on the top or bottom of your reservoir or on both ends as inlet or outlet. The Protium Inlet tube is recommended on all inlets to eliminate air recirculation.Specifications:Protium Frosted Acrylic CNC Machined Triple G1/4 BSPP Port Reservoir Cap.
