CHECK VALVE, 1" Hose Barb x 1" Hose Barb

PN: 5185 – 1″ Hose Barb x 1″ Hose Barb with Check Valve

This Geo-Flo brass check valve features 1" hose barb connections on both ends, designed for use with flexible hoses in hydronic or geothermal systems. It prevents backflow, ensuring unidirectional fluid movement. Constructed from durable brass for reliable, long-term performance.

Check valves are mandatory when installing multiple geothermal heat pumps that have individual pressurized flow centers. The check valve prevents fluid from bypassing the ground loop through one of the adjacent heat pumps. The hose barb check valve is the perfect solution when installing multiple units with reinforced rubber hose. The fitting features 1″ hose barb connections on each side and a replaceable check valve insert. The fitting halves are sealed with an O-ring and secured with a drop of thread locker that prevents accidental disassembly but allows field replacement or service of the check valve insert if it becomes necessary. (4) all-stainless steel hose clamps are included along with a label for the outside of the pipe insulation indicating the position and installation direction of the check valve. This hose barb x hose barb check valve is compatible with any 1″ hose kit. The check valve should be installed on the discharge side of the pump as shown in the graphic below. Be sure to verify the direction of flow on the flow center used as there are two standards in the industry.
