Designed for armored cables, this brass gland offers robust protection for electrical installations in Zone 1, 2, 21, and 22, meeting stringent ATEX and IEC certifications. Its primary function is to provide reliable strain relief, sealing, and secure cable entry into enclosures and electrical equipment, safeguarding critical processes and personnel from explosive gas and dust hazards. This cable gland is suitable for non-armored cables in flameproof (Ex d), increased safety (Ex e), and dust (Ex tb) applications. It features a versatile clamping range facilitated by three levels of removable seals, ensuring a tight and secure fit for various cable diameters. The M25x1.5 metric thread ensures compatibility with standard industrial enclosures and equipment. Manufactured by nVent, this gland exemplifies durability and reliability, even under extreme environmental conditions.
  • Suitable for SWA (steel wire armored), AWA (aluminum wire armored), SWB (steel wire braid), STA (steel tape armored), & shielded cable in flameproof (ex d), increased safety (ex e) and dust (ex tb) applications
  • Allow for double sealing of cable and jacket with upper and lower seals
  • The swivel retainer and grounding cone are adhered to the gland body by the o-rings to prevent any loose parts; to remove, simply pull these components slightly to detach
  • All metric thread cable glands are packaged as kits and includes a chloroprene washer, locknut and earthtag
  • All NPT thread cable glands are packaged as kits. Each kit includes a locknut and earthtag (except for NPT 3/8-in. cable glands which do not include locknut and earthtag)
  • Available in Metric (M) and NPT (N) thread type
  • Operating temperature from -40 C to 100 C with chloroprene seal and -60 C to 130 C with silicon seal
