Cable glands are essential equipment in many industries, including the outing lighting, and NEV industries. They are used to provide a watertight and dust-tight seal for cables, pipes, and hoses that pass through walls or paneling.

Cable glands are available in a variety of sizes, materials, and designs. It is important to consider the type of environment in which it will be used, as well as the diameter and cross-sectional area of the cable. Proper size selection is critical to ensuring a proper fit and seal. This article provides a brief overview of how to select the correct size cable gland for your application.

Why do you need a cable gland?

The purpose of the cable gland is to hold the cable in place, prevent the cable from moving around or being pulled out of the housing, and protect the cable from damage. Additionally, cable glands help keep out dust, moisture, and other environmental contaminants that could damage electrical equipment or compromise system safety. Cable glands also help ensure reliable, safe electrical connections between cables and equipment.

What is the difference between a cable gland and a cable entry device?

Cable glands are used to secure and terminate cables within an enclosure while cable gland is a more general term used to provide entry and exit for cables entering and exiting an enclosure. Both products are available in various sizes and materials to suit specific applications.

What is a cable gland?

A cable gland is a cable entry device used to relieve strain and create a seal around cables entering electrical enclosures or equipment.

What is a cable entry?

Cable entries can refer to the more general category of products used to manage and protect cables as they enter electrical enclosures. This category can include cable glands as well as other types of cable entry systems such as conduits, cable ties, cable clamps, etc.

Cable gland vs cable entry

Cable glands and cable entries are integral parts of electrical enclosures. Cable glands hold cables in place, while cable entries seal all openings and protect the inside of the enclosure from harsh external conditions.

What factors should you consider when choosing a cable gland?

Cable glands are usually made of metal or plastic and provide a tight seal around the cable to keep moisture and other contaminants out. When choosing the appropriate cable connector, there are several factors that you need to consider:

Type of cable

Different types of cables require different types of connectors. For example, an HDMI cable would require an HDMI connector, a USB cable would require a USB connector, etc.


Consider the specific application for which you need the cable and connector. Some applications may require specialized connectors that offer additional features such as water resistance or EMI protection.


Connectors are classified as male or female. Male connectors have pins, while female connectors have sockets. Make sure to choose the correct gender of connector for your needs.

Types of cable glands

There are different types of contacts, such as screw, crimp, and soldered. Choose the type of contact that is appropriate for the application and cable you are using.

Second, the fitting also features a leak-proof seal that ensures no drips or leaks, making it ideal for applications where fluid-tightness is critical.

Signal Type

Consider the type of signal that you will be transmitting through the cable and connector. Some signals, such as high-frequency signals, may require specialized connectors with low insertion loss and minimal return loss.

Environmental Conditions

For applications in extreme conditions, it’s important to ask questions that will determine what is necessary for cable and connector specifications. Protective plating or coatings may be necessary, so make sure to take these considerations into account. Doing so will ensure reliable use in harsh environments.

Are you utilizing this product indoors or outdoor?

Will it be located in a safe industrial area or in a hazardous or explosive environment?

What is the temperature and is it constant?

Is the surroundings humid or dusty?

Is there gas or corrosive substances nearby?


Cost can be a significant factor when choosing cable connectors. Be sure to consider the cost of the connector and cable, as well as the cost of installation and any special tools that may be required.

What are the benefits of using a cable gland?

A cable gland is a device used to terminate and secure the ends of cables. They are commonly used in industrial and commercial applications where cables need to pass through metal or plastic enclosures.

There are many different types of cable glands on the market, each designed for a specific type of cable and application. Selecting the proper cable gland for your application is important to ensure a snug fit and proper seal.

There are several benefits to using cable glands, including:

●  Strain Relief: Cable glands ensure that cables are securely clamped, reducing stress and strain on cables, especially where they enter panels or enclosures.

●  Cable Protection: Cable glands provide a protective barrier against moisture, dust, oil, and other environmental elements, helping to extend the life of the cable.

●  Environmental Sealing: Cable glands provide a secure, reliable seal that helps prevent water, dust, and other contaminants from entering the enclosure.

●  Cable retention: Cable glands help prevent cables from being pulled out of the enclosure or panel, which could cause damage to the cable and the equipment it is connected to.

●  Easy Installation: Designed for easy installation, the cable glands can be installed quickly and safely, helping to reduce installation time and cost.

●  Versatility: Cable glands are available in a variety of sizes and materials to suit a variety of applications and cable types, including armored, multiconductor, and flexible cables.

How do you install a cable gland?

A cable gland is a device used to connect and secure the end of a cable to an enclosure. Installing cable glands is a relatively simple process, specifically including the following steps:

Step 1. Determining the correct cable gland gauge

Choose a cable gland that is compatible with the size and type of cable you are using and that will fit in the hole in the panel or enclosure.

Step 2. Prepare the cable

Strip the outer jacket of the cable to expose the individual cores or wires, and cut the wires short if necessary.

Step 3. Install the cable gland body

Insert the cable gland body into the hole in the panel or enclosure, making sure it fits correctly and securely.

Step 4. Connecting cables

Insert the cable into the cable gland body, making sure it is centered and straight. If the cable gland has a jam nut, tighten it to clamp the cable in place.

Step 5. Sealed Cable Glands

If the cable gland has a gasket, place it over where the cable enters the body of the gland and tighten the jam nut to compress the gasket and create a watertight seal.

Step 6. Test installation

After installing the cable gland, inspect the cable for any signs of damage or stress and test the seal by spraying a small amount of water on the area around the cable gland. If there are no leaks, the installation is complete.


When selecting a cable gland, it is important to consider the environment in which it will be used, the type of cable gland thread used, the diameter of the cable, and the required sealing range.
