Brass Craft's new gas appliance connector program features the patented, easy-to-install Brass Craft Safety+PLUS Shut-off Fittings. In the event of a major gas connector rupture, this magnet-based device will shut off the gas supply to the appliance, similar to a circuit breaker. The gas shuts down only at the appliance where the problem exists; the rest of the gas system will continue to function as normal. When the gas problem is fixed, the Safety+PLUS fitting automatically resets itself. Other components of the gas appliance connector program include ball valves, fittings, adapters and gas connectors for ranges, water heaters and dryers.Brass Craft Subsidiary of Masco Corp.
