AD-U & RD-U Series Adaptors and Reducers provide a method of matching electrical

threadforms on Ex Equipment while maintaining certification.

Adaptors 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.

Reducers are used to reduce the entry thread of an enclosure to accept a cable gland

or connection device with a smaller thread.
