Description
Male x Female Thread Adapter: Exd/Exe, ATEX, IECEx, GOST-R, CSA

Redapt's AD-U series of Adapters provide a method of matching electrical threadforms on hazardous area approved equipment.  
Ex approval maintains hazardous location certification and the overall integrity of the installation.

Manufactured from hexagon material to facilitate an easy installation, this Adapter will convert holes which fit size M16 x 1.5 male threads to a female 1/2" NPT threaded hub.

Supplied complete with a captive O-Ring seal located within a recess on the face of the fitting, this provides protection from environmental damage, ensures the O-Ring is not displaced during installation and optimizes ingress protection.


The AD-U series of Adapters are certified to protection concepts Exd "Flameproof" and Exe "Increased Safety" for use in Zone 1 and Zone 2 applications.  Approved to the latest international standards, ATEX (CENELEC), IECEx and GOST-R hazardous area certificates are available.  Additionally, CSA approval certificates can be supplied to cover use in North American and Canadian Class I, Division 1 and Class I, Zone 1 applications.

While designed for use within the hazardous locations present in oil, gas and petrochemical installations, Redapt's Thread Adapters are also commonly used in Industrial & Commercial applications providing a quick and easy solution when connecting to international components or machinery.
