BASO K16BA-72 Thermocouple

The BASO K16BA-72 Thermocouple is a professional-grade 72-inch screw-in thermocouple engineered for standing pilot ignition systems. As part of the Husky series, this component is designed for high-heat environments, providing a reliable 25-35 mV open circuit range to ensure precise flame sensing. This specific model is identical to the K16BA-72H and serves as a direct replacement in various gas-fired applications, including commercial boilers, industrial furnaces, and water heaters. The 72-inch lead length offers the necessary reach for large-scale equipment where standard leads fall short. By maintaining a consistent millivolt signal to the gas valve, the BASO K16BA-72 prevents nuisance shutdowns and ensures the pilot safety circuit remains energized during standard operation. Built for the rigors of field service, this heavy-duty thermocouple facilitates simplified installation with its standard screw-in connection, making it a staple for contractors maintaining legacy standing pilot systems.

Key Benefits for HVACR Professionals

• Extended 72-Inch Length: Provides ample lead for large appliances and complex burner configurations where shorter thermocouples cannot reach.
• Husky Series Durability: Constructed to withstand higher ambient temperatures than standard residential thermocouples, reducing call-backs for pilot failure.
• Universal Pilot Burner Compatibility: The screw-in style connection fits most standard standing pilot burners utilized in the HVACR industry.
• Optimal Millivolt Output: Delivers a consistent 25-35 mV open circuit signal, ensuring reliable dropout timing and pilot safety.
• Direct Cross-Reference: Fully interchangeable with the K16BA-72H, simplifying inventory management and part identification.

Common Questions & Troubleshooting

What causes a BASO K16BA-72 to fail in a standing pilot system?
Failures are typically caused by heavy carbon buildup on the tip, improper flame impingement (flame should cover the top 1/2 to 3/4 inch of the tip), or "over-tightening" the nut into the gas valve, which can damage the internal copper lead or the insulation.

Can I use this thermocouple in a 750mV powerpile system?
No. The K16BA-72 is a standard 30mV thermocouple. It is not designed to power a thermopile/powerpile millivolt system, which requires a much higher output to operate the gas valve operator.

Is there a difference between the K16BA-72 and the K16BA-72H?
There is no functional or technical difference between these two model numbers; they are identical parts and can be used interchangeably in any 11/32-32 threaded gas valve connection.
