How to choose the right conduit gland for your application

Selecting the appropriate conduit gland for your application is essential to ensure safety, reliability, and efficiency in electrical installations. 

Conduit glands provide a secure means of attaching and securing the ends of electrical conduit to devices, enclosures, or other electrical apparatus. This blog delves into the factors you should consider when choosing the right conduit gland for your specific needs.

Do you have any questions about after reading this blog, please feel free to contact.

1. Understand the types of conduit glands

Conduit glands come in various configurations to suit different installation needs:

Straight conduit glands: These are available in male, female, or cable hose configurations. Male glands have external threads to fit into female fittings or in knock-outs, while female glands have internal threads to receive male fittings. Cable hose glands accommodate cable entry into the enclosure or equipment whilst providing an additional sealing on the cable.

90° conduit glands: Also known as right-angle glands, these are used for making cable entries at a 90° angle to the enclosure or equipment, which can be beneficial in space-restricted installations.

45° conduit glands: Similar to 90° glands but with a shallower angle, these provide a more moderate bend for cable entry while still offering flexibility in routing cables.

2. Choose the right type of thread

Conduit glands are available with various types of threads to accommodate different installation requirements:

ISO Threads or Metric Threads: These are standardized Metric threads defined by the International Organization for Standardization (ISO). ISO/Metric threads follow the metric system of measurement and are widely used in Europe and many other parts of the world. They offer precise thread dimensions and are suitable for applications where metric standards are preferred.

PG Threads (Panzer-Gewinde): PG threads are made to a technical standard which was created in Germany and which are subsequently used in Switzerland, Austria and other neighboring European countries. The PG threads are more and more replaced now by the ISO Metric threads.

NPT Threads: What ISO Metric threads are for Europe, NPT threads are for North America. Due to their tapered shape, they are self-tightening and therefore a seal or O-ring is not necessary. In terms of dimensions, they are precise and follow the US imperial system. They are the standard thread for industries in North America and the Middle East, but also widely used all over the globe.

3. Consider the material of construction

The material of the conduit gland is crucial depending on the environmental conditions where it will be installed:

Nickel plated brass glands: Popular for general purposes due to their durability and corrosion resistance. Suitable for both indoor and outdoor environments.

Stainless steel glands: Ideal for highly corrosive environments. They are more expensive but provide excellent durability and resistance to extreme conditions.

Plastic glands: Often used in applications where corrosion or chemical resistance is required. They are generally more economical but less durable than metal options.

4. Check the IP rating

The Ingress Protection (IP) rating is crucial in assessing a conduit gland’s effectiveness in protecting against solids and liquids. For a detailed explanation of IP ratings, please refer to our blog ‘IP Rating Explained’. A higher IP rating signifies better protection against environmental factors like dust and water. For instance, an IP68 rating indicates that the gland is dust-tight and can withstand submersion in water under specific conditions, making it ideal for outdoor or harsh environmental applications.

5. Size and compatibility

Ensure that the conduit gland matches the size of your conduit. A mismatch can lead to poor installation, inadequate protection, and even failure of the electrical system. It’s crucial to consider the inner and outer diameter of the conduit and the corresponding ferrule size for a proper fit. However, the trade size of the conduit is the determining factor for selecting a suitable fitting.

6. Certifications and standards

Look for conduit glands that comply with relevant standards and certifications. These may include:

UL (Underwriters Laboratories): Ensures the gland meets specific safety requirements

CSA (Canadian Standards Association): Indicates compliance with Canadian standards for safety and performance.

ATEX (ATmosphères EXplosibles): Necessary for equipment intended for explosive atmospheres.

IEC (International Electrotechnical Commission): Guarantees that the gland meets international safety and performance standards.

NEC (National Electrical Code): Compliance with the NEC standards ensures safe installation practices and regulatory compliance in the United States.

7. Special features

Some conduit glands come with special features that might be necessary for your application:

EMC (Electromagnetic Compatibility): These glands provide shielding against electromagnetic interference, crucial in environments sensitive to such disturbances.

Fire resistance: Look for fire-resistant features if the installation is in a fire-prone area.

Toxicity considerations: Certain conduit glands are designed to minimize toxicity, making them suitable for applications where exposure to toxic substances is a concern. These glands ensure compliance with safety regulations and standards related to material toxicity.

8. Consider the application environment

Finally, consider the environment in which the gland will be used. Factors such as extreme temperatures, potential mechanical impacts, and the presence of oils or chemicals should influence your choice. Make sure the gland material and type are suited to handle these environmental conditions.

Remember, the right conduit gland not only protects your cables but also ensures the overall reliability and efficiency of your electrical system.

Note: Clarifying conduit glands terminology

The term “conduit glands” is commonly used, but it’s important to clarify that this terminology may not be entirely accurate. In electrical installations, we differentiate between conduit fittings and cable glands. Conduit fittings are utilized with conduits to connect, protect, and navigate the conduit system, while cable glands are used to secure cables at termination points. Therefore, when referring to a conduit system, we use conduit fittings, and when dealing with individual cables, we use cable glands for proper terminology and clarity. Understanding this distinction helps ensure precise communication and proper selection of components for electrical installations. For a detailed explanation of the exact differences between conduit glands, conduit fittings, and cable glands, you can refer to our other blog post on this topic.
