Maxitrol RV48L Liquid Propane Pressure Regulator, 3/4" FPT Thread, 1-1/16" In and Out Opening, 1/2 PSIG In, 5"-12" WC Out (3/4" Propane Gas LP)

GAS TYPE & PRESSURE - Gas Type: Propane Gas (LP). Inlet gas pressure: 1/2 PSI. Outlet pressure range: 5" - 12" Water Column PIPE THREAD SIZE - 3/4" Inlet & 3/4" Outlet FPT GAS PIPE. Make sure you measure the gas pipe or regulator opening as close to 1-1/16 inch as shown in the picture’s table. CAUTION - This regulator has 1-1/16" openings for 3/4" gas pipes. The 3/4" gas pipe means interior diameter 3/4" but outside diameter is 1-1/16", refer to the pictures before buying. MARKING - Model: RV48L, Marking: 1/2 PSIG, Po 5" - 12". Inlet pressure 1/2 PSI. Adjustable outlet pressure 5"-12" Water Column. OPERATE TEMPERATURE - 32°F - 225°F (0°C - 107°C). Do not install the regulator too close to the heating equipment or use in very cold environment. Heat or cold can change the resistance of the spring inside the regulator. Attention: NOTE: GAS PRESSURE REGULATORS WILL NOT TURN OFF THE FLOW OF GAS. CAUTION: Never connect regulator directly to the propane supply source. Maxitrol regulators require an external regulator (NOT supplied). Install the external regulator between the propane supply source and Maxitrol regulator. Install the regulator properly with gas flowing as indicated by the arrow on the casting. *NOTE - Do not install the regulator too close to the heating equipment or use in very cold environment. How to find the correct pipe thread size WARNING: The NPT thread size is NOT referring to the size of the thread itself! The plumbing industry standard for the pipe sizes is NOT always as straightforward as measuring the pipe. Measuring the pipe will often mislead you into choosing the wrong pipe size. The "pipe thread size" is measured and based on the inside of the pipe. A lot of people measured the thread / the opening for the thread / outside diameter of the pipe, and thought that was the thread size. It was WRONG.
