The SB474 dual certified Exe/Exd gland offers an instant barrier solution where individual holes are punched through a silicone seal. You then pass through your individual insulated cores and compress to meet all of the requirement of a traditional barrier gland solution. This results in unparalleled speed of installation, inspection and flexibility, with no need for compounds or resin to achieve the Exd barrier seal, no curing time and instant gland completion.

Dual Certified ATEX/IECEx (along with many more) for use in Increased Safety (Exe), Flameproof (Exd), Restricted Breathing (ExnR) and Dust (Ext) protection concepts.
