Value Brand 24C487 Brass Thermowell Lagging

SKU CH-72AE-NST36

A brass thermowell with lagging extension protects temperature sensors in industrial processes

  • Product typeEnvironmental & Mechanical
  • Brass construction resists corrosion in harsh environments
  • Straight shank design fits standard 3/4 in MNPT process connections
  • Six-inch insertion length reaches deep into pipelines or vessels
  • Four-and-a-quarter-inch neck extension clears insulation or lagging easily
  • Prop 65 notice flags regulated substances for workplace safety compliance

Brass Thermowell for Industrial Temperature

The Value Brand 24C487 is a brass thermowell designed to protect temperature sensors in industrial process environments. Its straight shank and 6 inch insertion length suit standard stem fittings. A 4 1/4 inch neck extension provides clearance for insulation or lagging. The brass construction offers compatibility with many non-corrosive media.

Suitable for Lagged Pipework

This thermowell suits installations where lagging is applied and a neck extension is required to reach the process. It is not food safe, so it should not be specified for sanitary or potable water applications. Buyers needing corrosion resistance beyond brass capabilities should consider alternative materials. The item is restricted from sale in California due to Proposition 65 chemical content.

Six Inch Insertion Depth

The 6 inch insertion depth positions the sensor tip within the process flow for representative readings. The 3/4 inch male NPT thread mates with common process connections. Brass material limits use to pressures and temperatures within its mechanical range. Operations requiring higher pressure ratings or exotic alloys will need a different specification.

Questions about this item

What size thermowell opening does the 3/4 in MNPT brass thermowell need to fit into?

The 3/4 in MNPT brass thermowell requires a matching 3/4 in NPT female process connection on your vessel or pipe to thread into securely.

Will the 6 in insertion length reach the process fluid if my existing thermowell has a shorter bore depth?

The 6 in insertion length needs at least 6 in of bore depth plus the 4 1/4 in neck extension clearance; a shorter bore will prevent proper immersion.

How can I verify the 3/4 in MNPT brass thermowell is seated correctly after installation?

Check that the threads are fully engaged with no visible gaps, the 4 1/4 in neck extension clears insulation, and the sensor inserted to the 6 in insertion depth reads a stable, expected temperature.
