Honeywell rv48-66-0046 Gas Pressure Regulator 3/4 Inch Fpt

Product Description

The HONEYWELL rv48-66-0046 is a 3/4-inch FPT natural gas pressure regulator rated for 250,000 BTU/h at a maximum 1/2 psi inlet pressure. It delivers a regulated outlet pressure in the 3 to 6 inches water column (WC) range and ships with the 12A06 vent fitting included. This regulator is designed for use in gas appliance supply lines where precise downstream pressure control is required. Licensed gas technicians and HVAC professionals install this type of regulator as part of residential or light commercial gas system service and commissioning work.

This regulator is suited for natural gas systems requiring a 3/4-inch female pipe thread connection at both inlet and outlet. Typical applications include gas furnaces, boilers, water heaters, and commercial cooking equipment operating on natural gas distribution systems where inlet pressure must be stepped down to appliance-rated operating pressure. The included 12A06 vent fitting supports proper pressure relief venting per standard gas appliance installation requirements.

Installation Notes

Installation should be performed by a licensed gas fitter or HVAC technician in accordance with the International Fuel Gas Code (IFGC) and all applicable local codes. Shut off the gas supply and verify zero pressure at the work point before removing the existing regulator. Apply listed pipe thread sealant or tape rated for gas service to all threaded connections and verify for leaks with an approved leak detection solution after restoring gas pressure. The vent fitting must be installed and routed per the appliance and regulator manufacturer instructions.
