Cable Gland Selection Guide

Selecting the right cable gland is critical to ensuring the safety, durability, and efficiency of your electrical system. The ideal gland provides a secure seal, strain relief, and environmental protection, and is tailored to your specific cable type and installation conditions. This includes factors such as cable diameter, armor type, temperature range, and the presence of water, dust, or chemicals.

Consider factors such as material choice (nylon, brass, stainless steel), IP rating (IP67/IP68), thread type (metric, PG, NPT), and compatibility with armored or unarmored cable.

Cable Glands Types

  • Metal Cable Glands

    Our metal cable glands (usually made of brass or aluminum) are rugged and durable, making them ideal for heavy machinery, outdoor equipment, and industrial cabinets.

  • Armored cable gland

    Armored cable joints usually refer to electrical joints used to connect and protect armored cables. Their main function is to ensure the safety and stability of the cable connection part and prevent damage to the cable from the external environment.

  • Marine cable gland

    Marine cable connectors are cable connection devices designed specifically for ships and are usually used to ensure the stable operation of electrical equipment and systems on board.

  • Metal hose fitting

    Metal hose connectors are important accessories for connecting metal hoses to pipes, equipment or other metal hoses. The main function of metal hose connectors is to ensure sealing, pressure resistance and connection stability.

  • Cable Glands with Connectors

    Don’t want to remove pre-assembled connectors? Use our cable glands with connectors, which are specially designed to be inserted without removing the connector. These glands provide IP-rated sealing and strain relief.

Cable Gland FAQ

What materials are cable glands made from?

Cable glands are available in various materials depending on the application, including:

  • Nylon (PA66): Lightweight, cost-effective, and corrosion-resistant, ideal for general indoor use.
  • Brass: Strong, durable, and corrosion-resistant, commonly used in industrial and automation environments.
  • Stainless Steel (SS304/316): Highly resistant to corrosion and ideal for marine, chemical, and harsh outdoor applications.
  • Aluminum: Lightweight and suitable for moderate-duty applications.

What is the IP rating on a cable gland?

The IP (Ingress Protection) rating refers to the level of protection provided against dust and water. For example:

  • IP67: Dust-tight and can withstand immersion in water up to 1 meter for 30 minutes.
  • IP68: Dust-tight and can withstand continuous submersion in water beyond 1 meter.
  • Always choose a gland with an appropriate IP rating based on the environment where the cable gland will be used.

Can cable glands be used in hazardous or explosive environments?

Yes, ATEX-rated (explosion-proof) cable glands are specifically designed for use in hazardous or explosive environments, such as oil and gas refineries, chemical plants, and mining sites. These glands provide sealing and flameproof protection to prevent ignition in explosive atmospheres.

Can cable glands be used for both indoor and outdoor applications?

Yes, cable glands are versatile and can be used in both indoor and outdoor environments. However, for outdoor use, it is important to select glands with high IP ratings (e.g., IP67 or IP68) to ensure waterproofing and protection from environmental elements like rain, dust, and UV radiation.

How do I maintain cable glands?

Cable glands require minimal maintenance, but it is important to regularly check the following:

  • Ensure the gland is securely tightened and that the seal is intact.
  • Inspect for any signs of wear, corrosion, or damage.
  • Ensure that any pressure or strain relief features are functioning properly to avoid cable damage.
  • Clean glands as needed to remove dirt, dust, or moisture buildup.

Can I use cable glands for cables with connectors?

Yes, there are specialized cable glands designed for pre-terminated cables with connectors. These glands allow you to easily insert cables without having to disassemble the connectors, ensuring a secure seal and protection for the electrical connection.
