A Y Mcdonald 4215-191 Plug Valve 1/2 Inch Fnpt Brass Gas

Product Description

The A Y MCDONALD 4215-191 is a manually operated plug valve with check, designed for low-pressure natural gas and propane gas service on residential and light commercial house piping systems. Built with a brass body, this valve is rated for operating pressures up to 5 psi and is suitable for ambient temperatures ranging from 32 to 125 degrees F. A lever handle actuator provides straightforward on/off control. The valve connects via 1/2-inch FNPT fittings, making it compatible with standard threaded pipe installations. Licensed plumbers and gas fitters install this valve as part of the interior gas piping system, positioned between the meter outlet and the appliance inlet connection.

This valve is intended for indoor installation on gas house piping systems serving natural gas or propane appliances. Typical applications include the final shutoff point between a gas meter and a connected appliance such as a furnace, water heater, or range. The 1/2-inch FNPT end connections accommodate common residential gas line sizing. Series 10598, the valve measures 2 inches in length and 2.74 inches in height, fitting into tight spaces within typical residential mechanical rooms and utility areas.

Installation Notes

Installation must be performed by a licensed plumber or qualified gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC).
