Industrial Thermowell Brass 1-1/4-18

This brass thermowell protects temperature sensors in industrial process applications. The stepped shank design suits 3/4 in MNPT process connections with a 6 in insertion length. It is intended for maintenance and engineering teams who need reliable sensor isolation in piping systems.

Threaded Brass Shank For Sensor Protection

The unit threads directly into a 3/4 in MNPT fitting, eliminating the need for welding or flanges. A 1 3/4 in neck extension provides clearance for insulation or lagging around the pipe. This arrangement frees up sensor replacement without draining or shutting down the process line.

6 In Insertion Length For Standard Stems

The 6 in insertion depth matches standard 6 in stem thermometers and RTDs, giving full immersion in typical pipe diameters. Brass construction limits use to non-corrosive media and moderate pressure ranges. Buyers needing food-safe ratings or higher corrosion resistance should select alternative materials.

Questions about this item

What is the insertion length limit for sustained immersion?

The thermowell is rated for a 6 in insertion length, which defines the maximum depth for continuous process exposure.

How much heat transfers through the brass wall during all‑day operation?

Brass construction conducts process temperature to the sensor quickly, so the probe sees full heat load whenever the line is hot.

Which process connection must already exist on the vessel?

A 3/4 in MNPT threaded opening is required to install this thermowell.
