Why use brass cable glands

Now coming back to our topic of discussion, why should you use brass cable glands instead of any other material? The reasons are listed below:

Corrosion Resistance

Brass is an alloy from zinc and copper and hence corrosion resistant. The cables are used underground and also under aggressive working environments and hence cable glands are prone to rust and early damage. Some brass cable glands are plated with nickel and hence ensure better life for the accessories.

Temperature Proof

High voltage electric passes through the electrical equipment and hence cable glands linking this equipment must be fire retardant and neutral to high temperature. The brass cable glands do not turn soft when exposed to high temperature and hence the chances of leakages or breaks are reduced.

Safe and Secure

Brass cable glands are secure. These are available in various diameters and hence provide a perfect sealant to dust and water. In case of extreme loads, bend protection and strain relief clamps are provided with these cable glands.


Every cable differs in shape, size and configuration and hence has a unique cable gland requirement. The premium brass cable gland manufacturers of India can provide you with accessories as per the given specifications.

These cable glands are metallic outside but with plastic inserts inside to provide better protection against distortion. These standard brass cable glands are used in medical equipment, controlling devices, measuring devices and in machinaries. The prime features of brass glands are:

  • Liquid tight
  • Strain relief
  • Long threads
  • Lamellar designed
  • Reduced clamping range

#2. Double seal brass cable glands
These cable glands are also used in medical equipment and machinery but when more stress resistance and safety is needed. This kind of cable gland can operate under extreme temperatures, as much as 300 degree centigrade. The primary features of this kind of cable glands are,

  • Comes with double sealants
  • Wide clamping range
  • Special silicon sealing

#3. EMC brass cable glands
This unique cable gland is attached to the gland body and provides an easy access to the cables. EMC brass cable glands maintain integrity and electromagnetic shields. The key features of cable glands are,

  • Lower contact resistance
  • Wider gap between braided portion of the cables
  • Easy installation and removal of cables

#4. Marine brass cable glands
These standard cable glands used for ship decks and other marine applications. Natural, nickel, tin and chrome provide a natural finish to the brass cable glands.

Hence when buying brass cable glands the following facts should be kept in mind

  • Leak proof
  • Flameproof
  • Explosion proof
