Armstrong part FT15-B3: armstrong 15b3 3/4" pmo float & thermostatic repair kit for the Armstrong B3 float & thermostatic steam trap (B & BI Series).

Armstrong's B and BI Series float and thermostatic steam traps are made for heating service that needs continuous drainage and high air-venting capacity. The thermostatic air vent is charged to track the steam pressure-temperature curve from 20 inches of vacuum to 30 psig, venting air slightly below steam temperature across that range.
