“CR-U” type glands, certified Flameproof Ex d, Increased Safety Ex e & Restricted Breathing Ex nR are suitable for use in Zone 1, Zone 2, Zone 21, Zone 22, Group I Mining, Gas Groups IIA, IIB, IIC and Dust Groups IIIA, IIIB, IIIC.
Occasionally referred to as “potting glands”, they provide a compound barrier Ex d & IP seal on the cable inner cores, eliminating damage to cables that exhibit “cold flow” characteristics and an additional environmental seal on the outer sheath.
The unique features include, Peppers T-1000, the sealing compound that enables a quick and easy installation and an innovative barrier chamber that provides a cable acceptance that is on average 17% greater than other designs. The gland maintains IP66 & IP68 to 100 metres and is deluge proof without the use of an additional seal or deluge boot. It is supplied with an IP O-ring seal as standard on metric entry threads.

Notes:
* Gland size does not necessarily equate to the entry thread size.
* The IP O-ring seal is only available on metric entry threads. IP washers can be supplied for tapered entry threads.
* Please ensure that the IP O-ring is not used in conjunction with a flat IP washer.
* Dimensions (A) & (B) may differ for glands with non metric entry threads. Please refer to our “Thread Reference Tables” for specific dimensions.
* Where glands are fitted into non-metallic Ex e enclosures they must be included within the earth circuit of the system.
* The user should seek expert advice if intending to combine flammable and combustible dust in one environment/installation.
* Assembly instructions must be read prior to installation and adhered to in full.
* Peppers supply cable glands with parallel entry threads that conform to the flameproof threaded joint requirements of IEC/EN 60079-1 and other equivalent standards. They usually incorporate a thread run out according to the available machining techniques and will not have a full form thread for the entire length. Peppers will not be held responsible for clients’ installations where this has not been taken into account.
* To maintain the specified IP rating, clearance holes must be in accordance with EN 50262 Table 1 and the entry device should be suitably secured.
* The gland is supplied with the correct amount of the two-part compound, gloves and instructions to allow one complete termination.
* Gland kits can be supplied with a PTFE IP washer in order to maintain the temperature range if required.
