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.

ï Worldwide compatibility ñ keeping pace with the rapidly changing approvals and
to ensure worldwide compatibility, Redapt have North American Ex approvals for
both methods of hazardous location classification, Zones and Divisions, in addition
to our existing CENELEC approvals. Redapt can therefore offer Adaptors &
Reducers Ex de I&IIC and/or Class I Division 1 ABCD
ï Captive ëOí Ring Seal ñ is located within a recess on the face of the product
helping protect the ëOí ring from the environmental damage, ensuring the ëOí ring is
not displaced during installation and to optimise ingress protection.
Please Note:
Tapered male thread options are not normally supplied c/w O ring seal, thread sealant
should be used to maintain the desired level of ingress protection. If an ëOí ring seal is
required (Clearance holes) this can be available as an option.
316 Stainless Steel versions do not feature a marking band. This reduces the overall
length of Reducers by 5mm, it does not affect the overall length of Adaptors.
