BASO K16RA-72 Thermocouple

The BASO K16RA-72 is a professional-grade standing pilot thermocouple engineered for high-demand thermoelectric applications in commercial and residential gas systems. Featuring a heavy-duty nickel-plated sheath, this 72-inch lead provides superior corrosion resistance and thermal durability compared to standard copper alternatives. Designed to operate within a 25-35 mV open circuit range, the K16RA-72 ensures stable millivolt output to the gas control valve, preventing nuisance drop-outs and ensuring reliable pilot safety. This model is technically identical to the K16RA-72H, offering a direct drop-in replacement for maintenance and repair cycles. For contractors managing gas furnace ignition or water heater assemblies, the extended 72-inch length provides the necessary clearance for large-scale equipment footprints. The Baso Gas Products construction prevents premature oxidation of the hot junction, maintaining consistent conductivity in high-temperature environments.

Key Benefits for Technicians

• Extended 72-Inch Lead: Ideal for large burners and industrial standing pilot setups requiring significant distance between the pilot assembly and the gas valve.
• Nickel-Plated Finish: Provides an extra layer of protection against harsh combustion byproducts, extending the service life of the millivolt thermocouple.
• High-Output Performance: Delivers a consistent 25-35 mV range to ensure the electromagnetic coil in the safety valve remains securely energized.
• Universal Compatibility: Seamlessly replaces K16RA-72H and other standard 11/32-32 Emerson or Honeywell style threaded connections.

Common Questions

What is the difference between the K16RA-72 and the K16RA-72H?
Technically, they are the same component. The "H" suffix often denotes bulk packaging for high-volume OEMs, but the specifications, thread sizing, and millivolt output are identical for field replacement.

Can I use this thermocouple in a 750mV powerpile system?
No, this is a standard 30mV class thermocouple. It is designed for pilot safety circuits, not for powering a millivolt thermostat circuit which requires a thermopile.

Why choose nickel-plated over copper for standing pilots?
Nickel plating prevents the copper from scaling and degrading when exposed to continuous pilot flames, which is critical for standing pilot ignition systems that run 24/7.
