Features a 1/8 pressure tap on both first and second stage portions. The Streamline 720C Regulator is sized for most RV applications while the 720A and 720B will meet most domestic applications. With the flow limiting device minimizing the discharge through the vent, the 720A and 720B are ideal for pool heater applications. By allowing you to vent the regulator relief valve with 3/8 copper, the installation costs can be minimized.
