BASO K19AT-30 Thermocouple

The BASO K19AT-30 Thermocouple is a professional-grade Super Slim Jim universal replacement designed for high-reliability performance in standing pilot ignition systems. Built for the rigors of field service, this 30-inch coaxial thermocouple features a robust construction capable of operating in extreme environments with a maximum hot junction temperature rating of 1300°F (704°C). This makes it an ideal solution for consistent flame sensing in furnaces, kilns, and commercial fryers where standard probes may fail.

Engineered for maximum compatibility, the K19AT-30 serves as a direct drop-in for BASO G and H series valves, Basoids, and Basotrols. Its universal replacement design also allows for seamless integration into pilot burner assemblies from several major manufacturers, including Honeywell, Robertshaw, and Johnson Controls. The unit provides a reliable 25-35 mV open circuit range, ensuring the electromagnetic coil in the gas valve remains energized during normal operation. This kit includes the necessary knurled spring clip and two lead adapters, simplifying thermocouple installation and ensuring a secure fit in the pilot bracket.

Key Benefits for Contractors:

• Universal Compatibility: Replaces a wide array of 30-inch thermocouples used in standing pilot applications across multiple brands.
• High-Temperature Durability: Rated for 1300°F to stay functional in high-demand industrial heating environments.
• Low-Voltage Precision: Delivers a consistent millivolt output between 25 and 35 mV for stable safety shut-off performance.
• Installation Ready: Includes a spring clip and adapters to accommodate various pilot burner mounting styles without extra trips to the van.

Common Questions:

Will this thermocouple replace my current Johnson Controls K19 series?
Yes, the BASO K19AT-30 is the direct universal replacement for the K19AA and K19AT series, provided the 30-inch length meets your application requirements.

What is the thread size for the gas valve connection?
This thermocouple uses the standard 11/32-32 male nut connector common to most thermoelectric gas valves.

Can I use this on a high-heat commercial fryer?
Absolutely. With its 1300°F rating and Super Slim Jim profile, it is frequently used as an equivalent replacement in floor fryers and other high-output cooking equipment.
