Compression Fittings

Thermocouple compression fittings provide extra security for your thermocouples. Compression fittings help secure your sensors in place. This helps your thermocouple sensors to achieve the correct insertion length and stay properly seated for reliable, accurate readings.

At GeoCorp, we manufacture several different types of thermocouples and thermocouple supplies. That’s why we provide many different options for our compression fittings, including:

  • Brass or Stainless Steel
  • Metal, Teflon, or Lava Seals
  • Sheath Diameters: 1/16″, 1/8″, 3/16″, 1/4″, 5/16″, 3/8″, 1/2″
  • 1/8″ NPT, 1/4″ NPT, & 1/2″ NPT
  • Other sizes also available


Your business relies on good information to succeed. Quality compression fittings can keep your thermocouples properly mounted for consistent temperature readings. At GeoCorp, we pride ourselves on providing our customers with what they need, so we personally test every compression fitting we manufacture to ensure that you’re getting the best product possible.

Make sure that your thermocouples are in the best position to benefit your business. We’ve been manufacturing thermocouple supplies since 1989 and can help you achieve accurate temperature readings through quality products. Contact GeoCorp today about compression fittings for thermocouples.
