Zeagle Regulators Specifications and Features Comparison Chart

All Zeagle Diaphragm Regulator Models share the same internal components. The differences between diaphragm models are in the hose orientation, environmental sealing, cold water features, second stage controls, and flow patterns within the first stage housing. The ReZort and RaZor are both Flow-by Piston Regulators that also share internal parts between them.  The RaZor combines Valve and Regulator components into one body.
