From windblown dust and debris to rain, sleet, and snow, Hongxiang’s cable gland housings are designed to withstand a variety of harsh environments. What some people don’t know is that if a cutout is made in the box of the waterproof case, the waterproof case will lose this function. How do you solve this problem? Don’t worry – we have a solution.

Waterproof cable glands are a special type of cable connector that can be used to accommodate cutouts while maintaining the IP rating of the watertight enclosure.

This article provides an overview of the different types of waterproof cable glands available in the market, along with their main features and benefits.


waterproof cable glandsWhat are waterproof cable glands?

Cable glands, also referred to as cable clamps, provide an effective way of connecting cables within electrical and electronic enclosures. Their primary purpose is to maintain watertight sealing around the wires or cables entering the enclosure. The anatomy of a cable gland consists of a body, a nut, and two potential components – gaskets or cable seals. These components can be either integrated separately within the gland body or assembled together as one unit.

Depending on the intended application, waterproof cable glands are generally made with brass, plastic, nylon, aluminum, or stainless steel. The proper material should be selected to ensure reliable performance.

Waterproof cable glands are purpose-built for tough environments and offer a variety of features to protect cables, such as explosion-proofing, flame resistance, EMI/RFI shielding, and UV stability. Moreover, they can provide strain relief to reduce strain on the cable body and safeguard its components from harm.

Waterproof cable glands are indispensable in many industries that have custom housing cutouts with cables. Examples of their use include junction boxes, control boxes, circuit breakers, and other enclosures. They can be found in marine equipment (ships and offshore drilling), communication stations, automatic industries, and more. Thanks to their versatile nature, waterproof cable glands provide superior protection for all kinds of cables.

Different types of waterproof cable glands

Waterproof cable glands are essential in many industries and applications where the ingress of water, dust or other contaminants must be kept out. There are many different types of waterproof cable glands on the market, each with its own advantages and disadvantages. In this article, we’ll take a look at some of the most popular types of waterproof cable glands and compare their characteristics.

One of the most common types of waterproof cable glands is the IP68 cable gland. IP68 cable glands are designed for harsh outdoor environments. They’re usually made of a durable material like stainless steel or nylon and feature a sealing ring that helps create a watertight seal.

Another popular waterproof cable gland is the strain relief cable gland. Strain relief cable glands are designed to provide additional support for cables that may be subject to strain or tension. They are typically used in industrial and outdoor environments where cables may be exposed to harsh conditions or frequent movement. Typically made of durable materials such as nylon, stainless steel, or aluminum, these cable glands are designed to hold cables in place by gripping them tightly to prevent them from moving or pulling out of the device or equipment they are connected to.

What are the benefits of using waterproof cable glands?

Watertight cable glands help ensure the long-term reliability, safety, and performance of electrical installations while reducing maintenance and replacement costs.

The specific performance is as follows:

Dust and Dirt Resistant

In addition to protecting against moisture, waterproof cable glands also keep out dust and other contaminants that can damage cables and equipment.

Moisture Protection

Waterproof cable glands provide a safe and reliable method of sealing cables against the ingress of water or other liquids. This helps prevent damage to cables and other electrical components and reduces the risk of electric shock and other hazards.

Increased Safety

Watertight cable glands help increase the overall safety of electrical installations by providing a safe and secure seal around cables. They help reduce the risk of fire, electric shock, and other hazards.

Increased durability

Watertight cable glands are usually made of durable materials that resist corrosion, abrasion, and other types of damage. This helps extend the life of cables and other electrical components and reduces maintenance and replacement costs over time.


Watertight cable glands are available in a variety of sizes and configurations, making them suitable for a variety of applications and environments. They can be used on armored and unarmored cables, as well as in hazardous and hygienic environments.

How do waterproof cable glands work?

Waterproof cable glands are the ideal accessory when you need to create cable entry or exit in a watertight enclosure without exposing your electronics to the risk of water and dust ingress. But how do they work?

Watertight cable glands work by providing a watertight seal around a cable or connector. They are usually made of a durable material like plastic or metal, and screw or clip over the cable to create a tight seal. This seal prevents water and other liquids from reaching electrical connections, preventing short circuits or other problems.

Are there any disadvantages to using waterproof cable glands?

While there are many advantages to using waterproof cable glands in electrical installations, there are some potential disadvantages to consider, including:


Watertight cable glands can be more expensive than traditional cable connectors or other types of cable entry solutions. This is because they are designed to provide a high level of protection against moisture, dust and other contaminants.

Installation Complexity

Installing waterproof cable glands can be more complicated than traditional cable connectors, especially if the installation requires a high degree of accuracy or precision. This results in longer installation times and increased labor costs.

Limited flexibility

Watertight cable glands are designed to seal cables from moisture and other contaminants, which can limit their flexibility and versatility. This means they may not be suitable for every type of application or environment.


Choosing a Waterproof Cable Gland

When selecting waterproof cable glands for your electrical installation, it is important to consider several factors to ensure you select the correct type and size for your specific application.

Here are some key factors to consider:

Cable size and type

The cable gland you choose should be compatible with the size and type of cable you are using. Make sure to measure the cable diameter accurately to ensure you select the correct size gland.

Environmental Factors

Consider the environment in which the cable gland will be installed, including exposure to moisture, dust, temperature extremes, and other factors. Choose glands designed to provide adequate protection against these environmental factors.

Hazardous Area Classification

If installing in a hazardous area, consider cable gland classification and certification requirements. Installations in certain hazardous areas may require explosion-proof cable glands.

Material Compatibility

Make sure the gland material is compatible with the cables and other components in the installation. This is especially important for hygienic applications since the gland material must be corrosion-resistant and easy to clean.

IP Rating

Look for cable glands that meet or exceed the IP (Ingress Protection) rating for your installation. The IP rating indicates the degree of protection provided by the gland against dust and water.


Watertight cable glands provide a watertight seal around cables, preventing moisture and water from damaging sensitive electrical components. When it comes to choosing a waterproof cable gland for your watertight enclosure, the right choice can make all the difference. The ideal solution is to protect your IP and NEMA ratings and keep your electrical equipment in top operating condition for years to come.
