Armstrong International A21959-1 Gasket A typical silicon carbide igniter

A typical silicon carbide igniter should show a measurable resistance

preventing furnace short cycling or total system lockout caused by heat exchanger overheating

Why would my Weil McLain boiler have a blank display while the inducer is still running

oxidation eventually degrades the metal rod's conductive properties

it connects via 1/4-inch barbed nipples typically used with 3/8-inch OD polyethylene tubing

Armstrong International A21959-1 Gasket A typical silicon carbide igniterThe Armstrong International A21959 1 is a critical replacement steam trap gasket engineered specifically for A6 and B6 Series Float & Thermostatic (F&T) traps. Designed to maintain a high integrity seal under fluctuating pressure and temperature cycles, this component is essential for heavy duty industrial steam systems. In F&T applications, maintaining the boundary between the trap body and cap is vital to prevent steam loss and ensure the modulated
