Automotive Exhaust Gas Thermocouples

Exhaust Gas Thermocouples

Precision. Durability. Performance.

Our Exhaust Gas Temperature (EGT) Sensor is engineered for racing, tuning, and testing applications, delivering accurate and immediate temperature readings in extreme conditions. Designed and manufactured from premium materials, this sensor is built to withstand the most demanding environments.

Key Features

Fast & Accurate Readings

The exposed-tip sensing junction ensures rapid response to dynamic temperature changes. Response time as low as 150 msec.

Extreme Heat & Vibration Resistance

Built to endure temperatures up to 2300°F (1300°C) and heavy-duty use in high-performance applications.

Versatile Fitment

Designed to fit most internal combustion engine exhaust systems from 0.75” to 4” in diameter with minimal modifications.

Premium Build Quality

The 0.250” (6.35 mm) diameter probe features an option for a 90-degree bend for easy installation in tight spaces.

Durable Stainless Steel Construction

Includes an adjustable 1/8” NPT compression fitting adapter (316 stainless steel) for secure mounting. Also available in Inconel 600 sheath with magnesium oxide (MgO) filling (for higher temp.)

Heavy-Duty Cable Protection

The stainless steel over-braided cable ensures superior abrasion resistance, with FEP-insulated signal wires for reliability.

Multiple Length Options

Available in 6 feet (1.8 meters) or 12 feet (3.6 meters) cable lead lengths. Custom lengths available upon request, please fill our order worksheet in
