McDonnell & Miller 317354 Breaker and Gasket Els PW 17895 this thermal limit switch isThe McDonnell & Miller 317354 is the critical TC V vacuum breaker and gasket assembly engineered for high performance hot water boiler systems. This specific mechanical component is a direct fit solution for the upper valve of Series TC 4 Test N Check configurations, allowing for the rapid evacuation of water from the float chamber during routine diagnostics. By admitting atmospheric air when a vacuum condition occurs, the model TC V prevents back
