Exd “Flameproof” Type “A” & Type “B” Stopping Plugs

Redapt’s PA-D and PB-D Series of Stopping Plugs provide a method of blanking off unused entries in hazardous area approved equipment whilst ensuring the integrity and Ex approval of the installation is maintained.

The PA-D Series or Type A Stopping Plugs are designed to be installed from the outside of an enclosure and tightened with an appropriate allen key. When installed they fall flush with the outside of the enclosure wall.

The PB-D Series or Type B Stopping Plugs are designed to be installed from the outside of an enclosure. The hexagon recess is located on the inside and the plug is tightened with an appropriate allen key. Due to this feature they are sometimes referred to as tamper-proof stopping plugs. When installed they fall flush with the outside of the enclosure wall.

Redapt’s Type A and Type B Stopping Plugs are designed for hazardous area applications and are certified to protection concept Exd “Flameproof” for use in Zone 1 and Zone 2 applications.

Approved to the latest international standards stopping plugs can be supplied with ATEX (CENELEC), IECEx, and GOST-R hazardous area certificates.

In addition CSA approval certificates can be supplied to cover use in North American and Canadian Class I Division 1 and Class I Zone 1 applications.
