The Redapt AD-U and RD-U series of Adapters and Reducers match-up electrical thread-forms on what is known as “Hazardous Area” approved equipment while making certain that the integrity and Ex approval of the installation is fully maintained.

Quality assured: Our Adapters and Reducers are made from hexagon material for easy installation and come complete with a captive O-ring seal for metric male threads. The O-ring is located within a recess on the face of the product, helping to protect the O-ring from environmental damage and ensuring it is not displaced during installation. NPT male threads are tapered which do not require the use of an O-ring, however are used in combination with a non-hardening thread sealant to increase the IP rating.

Our Stopping Plugs are used to seal unused cable gland or conduit entries in Ex approved Explosion-proof (Flameproof) & Increased Safety enclosures, maintaining the hazardous location certification and the overall integrity of the installation.

*Explosion-proof or Flameproof? Which is it?

Both terms are correct and are used interchangeably, where Explosion-proof is the vernacular used in North America, while Flameproof is the preferred International term. This protection method is used to contain an explosion from within the enclosure and to prevent sparks from within its housing from igniting any gases, vapors, or dust in the surrounding atmosphere.

What is the difference between an Adapter and Reducer?

Basically, Adapters have a smaller male thread than female thread, whereas Reducers have a larger male thread than female thread. Adapters are used where the size of the connection device or cable gland is larger than, or equivalent to in size, to that of the conduit entry thread of the enclosure.

Reducers are employed where the size of the connection device or cable gland is smaller to that of the conduit entry of the enclosure.
