Maxitrol KT10460 Tube R-410A this Antunes pneumatic switch isThe Maxitrol KT10460 is a specialized by pass tube engineered specifically for the MR212G modulating gas valve. For veteran technicians managing direct fired burners and negative pressure systems (pull through applications), this OEM component is critical for maintaining a stable minimum firing rate. When the main valve is closed, the KT10460 bypass tube ensures a consistent low fire to the heater, preventing flame instability during the modulating
