Redefining what a thermal well can be

At Gas Turbine Specialty Parts LLC, we’ve spent over 25 years solving the most challenging problems in gas turbine instrumentation. Our team combines decades of hands-on experience with innovative engineering to deliver solutions that outperform traditional approaches.

Our patented multi-piece exhaust thermowell represents a fundamental rethinking of thermowell design. While the industry standard has always been a single-piece construction, we asked: “What if there’s a better way?”

The answer is our innovative 4-component thermowell system that accommodates thermal expansion, provides built-in strain relief, and dramatically extends the life of your thermocouples. Where traditional thermowells fail within a few thousand hours, ours are engineered for 150,000+ hours of reliable operation.

What Makes Us Innovative?

The definition of a thermowell has always been “one piece.” We challenged that assumption. Our 4-component design allows the thermocouple to float within the housing, tracking thermal expansion and maintaining proper seating at all times. This eliminates the fretting, sticking, and head breakage that plague conventional designs.
