BASO K16FA-18 Thermocouple

The BASO K16FA-18 Thermocouple is a high-performance standing pilot ignition system component designed for reliable flame sensing in commercial and residential gas applications. This 18-inch thermocouple generates an open circuit millivolt range of 25 to 35 mV, ensuring stable communication with the safety shutoff valve. It features a specific junction lead length of 3.546 inches, making it a critical HVAC replacement part for systems requiring precise terminal alignment. As a direct equivalent to the K16FA-18H model, it offers seamless BASO gas valve compatibility and drop-in integration for technicians servicing boilers, water heaters, and space heaters. The robust junction construction is engineered to withstand high ambient temperatures within the pilot burner assembly while maintaining consistent millivoltage output. For contractors performing thermocouple troubleshooting, this unit provides the durability and electrical precision necessary to prevent nuisance lockouts and ensure safe pilot operation under varied load conditions.

• Optimized Millivolt Output: Delivers a consistent 25-35 mV range to ensure reliable gas valve holding current.
• Broad Compatibility: Serves as a 100% identical replacement for the K16FA-18H, simplifying truck stock requirements.
• Precision Lead Length: The 3.546-inch junction lead provides the necessary reach for complex pilot burner configurations.
• Rugged Construction: Designed specifically for standing pilot environments where high-heat cycles are frequent.

Is the BASO K16FA-18 compatible with K16FA-18H gas valves?
Yes, the K16FA-18 and K16FA-18H are functionally and physically identical, sharing the same technical specifications and mounting requirements.

What is the proper millivolt reading for this thermocouple?
In a standing pilot setup, you should expect an open circuit reading between 25 and 35 mV. If the reading drops below the valve's drop-out range, the safety magnet will disengage.

Can I use this 18-inch lead if my previous thermocouple was 12 inches?
While the 18-inch length provides flexibility, ensure the excess lead is coiled away from direct heat sources to prevent thermal degradation of the copper sheath.
