Featuring Metallic Adaptors and Reducers

Certified Adaptors Reducers Peppers Cable Glands

Product description:

“AR” Series Certified Adaptors & Reducers provide a method of matching electrical thread
forms on Ex equipment whilst maintaining Ex d, Ex e, Ex tb and Ex nR methods of explosion
protection. Approved for use in mining (except Aluminum) and surface installations, they
maintain IP66 & IP68 for IEC type applications and Class I Division 1 and NEMA 4X for
CEC / NEC type applications. All external metric threads are fitted with a nitrile O-ring
as standard.
