Armstrong A21959-1 B6 Gasket for A6 Float & Thermostatic Steam Trap

Armstrong part A21959-1: b6 gasket for the Armstrong A6 float & thermostatic steam trap (A & AI Series).

Armstrong's A and AI Series float and thermostatic steam traps serve industrial applications from 0 to 175 psig and use a balanced-pressure phosphor-bronze bellows caged in stainless steel. They suit heat exchange equipment that must vent air and non-condensable gases quickly. The AI Series adds in-line connections with the same internals as the A Series.
