When should you choose cable glands with brush seals?
Cable glands with brush seals are the right choice when the installation requires good flexibility, easy cable routing and the possibility of air circulation in the enclosure.
They are often used in control cabinets where cooling is via natural ventilation and where cables may need to be moved or supplemented.
Common uses:
- enclosures with heat generation
- installations without watertightness requirements
- retrofitting and frequent cable changes
- protection against dust and debris
When is this solution not the right choice?
Cable glands with brush seals are not suitable in environments where sealing against water, moisture or high IP classes are required.
Avoid brush sealing when:
- the enclosure must be IP-rated against water
- the installation is outdoors
- high protection class required per cable
Suitable options in these cases:

FAQ – Frequently asked questions about cable glands with brush seal
Can brush sealing withstand IP-rated environments?
No, cable glands with brush seals are normally not intended for IP-rated environments with requirements for sealing against water or moisture.
They provide protection against dust and dirt but lack a seal that can withstand liquid penetration.
Does brush sealing affect the cooling in the enclosure?
Yes, brush sealing allows air to flow through the enclosure.
This can contribute to passive cooling by allowing heat to be dissipated via natural ventilation, which is one of the solution's main advantages.
When is another cable entry a better choice?
Another cable gland is a better choice when the installation requires water sealing, high protection class or individual strain relief per cable.
In such cases, sealing cable entry systems or cable glands are more suitable solutions.
