Features:Made of aluminum, brass and stainless steel material, it is extremely durable.There is a 2-point screw hole on the top for easy installation to other equipment.A built-in check valve protects your shunt and prevents gas backflow.Run multiple lines from one CO2 source. The distributor allows you to split gas supply into multiple lines. Each line has its own shutoff valve. Due to the one-way valve mechanism, the pressure drop between the ball valves in these manifolds is approximately 2 psi. You will need to set the pressure on the regulator to 2 psi above the pressure required in the keg.) Specification:Barbed Specifications: 7mm. Material: Stainless steel, aluminum Color: SilverSize: 240 x 90 x 30mm / 9.45 x 3.54 x 1.18 inch (appr.) Package List:1 x 4 Way Beer Splitter Features ENHANCED HIGH QUALITY:4 way beer splitter made of high-quality aluminum, brass and stainless steel, Co2 air gas beer splitter is very durable, non-toxic, rust-proof, safe and odorless, and easy to clean and use. EASY TOUSE:There is a 2-point screw hole on the top, which can be easily installed to other equipment, easy to install and use. Can quickly dispense beer and beverages for guests. SAFETY DESIGN:4 way air gas splitter built-in check valve protects the diverter and prevents gas backflow. The gas manifold can divide the conveyed gas into several parts to serve the draft beer system. MULTIPLE FUNCTION:Run multiple pipelines from one CO2 source. Manifold air gas splitter distributor allows you to divide the gas supply into multiple lines. Each pipeline has its own shut-off valve. WARM PROMPT:Brewing quadruple shunt due to the one-way valve mechanism, the pressure drop between the ball valves in these manifolds is approximately 2 psi. You need to set the pressure on the regulator to be 2 psi higher than the pressure required for the keg.
