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 M20 x 1.5 male threads to a female 1/2-14 NPT threaded hub. Comes standard with a Nitrile O-Ring.

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!

Pressure washer fitting

Very good service. I had a pressure washer that was missing a fitting out of the pump. They helped me find the proper fitting that nobody else carried and made sure that I got it at a fair price. I highly recommend anybody that needs things of this matter to use these people.

Hazardous area fittings are always tricky to find on short notice. When some fixtures arrived with metric threads after expecting NPT, I was able to get the proper conversion fitting quickly and at a very reasonable price.

I needed some very hard to find hydraulic adapter fittings. Thread Tool Supply had them (in stock) and delivered them to me promptly. I was extremely pleased with the availability and service all for a very reasonable cost. Thanks!
