Brass thermowell for industrial temperature sensing
This brass thermowell protects bimetal thermometers in process piping and vessels. The straight shank and 3/4 inch MNPT threads suit standard instrument connections. It is built for technicians and plant engineers who need reliable temperature measurement in water, oil or steam service.
Pressure rating drops as temperature rises
At 150 degrees F the thermowell withstands 3170 psi, while at 350 degrees F the rating falls to 2930 psi. The four inch insertion length reaches the flow stream for accurate readings under sustained operating conditions. Brass construction resists corrosion in non-aggressive media.
Threaded mounting simplifies installation
The 3/4 inch male pipe thread fits existing fittings without welding. Brass material allows easier thread engagement than stainless alternatives and reduces galling during maintenance. California Proposition 65 warnings apply because the alloy contains listed chemicals.

Questions about this item
How hot can the brass thermowell run continuously without exceeding its pressure rating?
It is rated for 150 °F at 3170 psi and 350 °F at 2930 psi, so the maximum safe temperature depends on the system pressure you apply.
What thread size must my process connection have for this thermowell to seal properly?
The thermowell has a 3/4 in MNPT external thread, so your fitting needs a matching 3/4 in FNPT port.
Will the 4-inch insertion length reach the flow stream in my existing 3-inch pipe tee?
With a 4 in insertion length the tip extends 4 inches from the mounting face; verify your tee geometry to confirm it reaches the centre of the stream.
