Frequently Asked Questions

What is the SPENCE threaded thermowell used for?

The SPENCE threaded thermowell (MPN 99J) is used to protect temperature sensors in industrial piping systems, such as steam or process lines. It allows accurate temperature measurement while shielding the sensor from high pressure, flow, and corrosive media. Common applications include HVAC ducts, boilers, and temperature regulation loops.

What are the specifications of the SPENCE threaded thermowell?

The SPENCE threaded thermowell (MPN 99J) is made of brass with a 15 5/8 in stem length, 12 1/2 in insertion length, and 1 in stem diameter. It has a maximum operating pressure of 250 psi and a maximum operating temperature of 400°F. It is designed for threaded installation in temperature regulator and duct sensor applications.

Where to buy the SPENCE threaded thermowell worldwide?

You can source the SPENCE threaded thermowell (MPN 99J) through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide reliable sourcing for this SPENCE component.

How to install a SPENCE threaded thermowell?

To install the SPENCE threaded thermowell, first ensure the process line is depressurized and cool. Apply thread sealant to the NPT threads, then hand-tighten the thermowell into the mating fitting. Use a wrench to snug it without over-torquing. Insert the temperature sensor fully into the thermowell and secure the connection. Always follow the manufacturer's guidelines for your specific sensor.
