ATEX Certified Explosion Proof Thread Adapter

Adapters are used where the thread size of the cable gland or connection device is larger than, or of an equivalent size, to the entry thread of the enclosure. Ex approval maintains hazardous location certification and the overall integrity of the installation.

This Adapter will convert holes which fit size 1/2" NPT male threads to a female M20 x 1.5 threaded hub.

Designed for use within the hazardous locations present in oil, gas and petrochemical installations. They are also commonly used in Industrial & Commercial applications in place of standard industrial grade adapters providing a quick and easy solution when connecting to international components or machinery.

Proudly made in the USA!

Good quality fittings, and they worked as intended.

IT/Automation

The adapter is exactly what I need. It is also pretty compact so it affects old installs with new equipment (that need the adapter) as little as possible.
