IP68 Rated Metal Cable Glands – Brass & Stainless Steel Industrial Solution

2026-04-18

The use of Metal Cable Glandsis crucial for providing protection to industrial cabling and ensuring a secure connection in harsh conditions. Metal Cable Glands offer reliable cable entrance points and prevent damage to sensitive electrical systems. They are critical throughout a variety of industrial sectors requiring marine, explosive, or extreme heat. Selecting the best Metal Cable Gland for each application is important to ensure reliability and safety. In this guide, we will provide information regarding brass and stainless steel gland equipment as well as the different types of threads, IP rating and uses associated with each of these metals.

Metal Cable Glands Defined

A Metal Cable Gland connects a wire from a power source to a piece of equipment, providing environmental protection for both the wire and the equipment. Metal Cable Glands are commonly used in industrial, marine, and hazardous environments for both cable management and entry into equipment. In addition to providing strain relief to the wire, they also seal, ground and provide explosion proof protection to both the cable and the equipment.

The most common metals used in the production of Metal Cable Glands are brass and stainless steel, both offering different advantages that can be matched to specific applications.

IP68 Metal Cable Glands - Key Features

The IP68 rating denotes that the item has the highest degree of protection from solid objects and water ingress.

🛡️
Dustproof and waterproof: They are rated as 'dust-tight' and 'waterproof', meaning they're protected from dust and can be safely submerged in water for prolonged periods of time.
⚙️
Durability: They are designed for durability in extreme conditions, allowing for additional protection from abrasion and damage.
🌡️
Temperature tolerance: They can operate in higher and lower temperature extremes than most units; thus, they are suitable for industrial and outdoor applications.

IP68 rated Metal Cable Glands are found in various applications such as power distribution systems, automation equipment, offshore production facilities, and manufacturing plants.

Brass vs. Stainless Steel Metal Cable Glands

When you are looking at metal cable glands, deciding whether to use brass or stainless steel cable glands will depend primarily on your particular needs. So, what's the difference?

Brass Cable Glands

Brass is made from equal parts of copper and zinc and offers excellent corrosion resistance. This is one of the primary reasons manufacturers select brass cable glands for their manufacturing processes.

  • Electrical conductivity: Brass is an excellent conductor of electricity, making it a great choice for high voltage applications.
  • Cost-effectiveness and customizability: Brass is a cost-effective solution (and can be plated with nickel or other materials) wherein manufacturers can customize it to provide added protection.
  • Wide industrial suitability: Brass cable glands work well in all industries.

Stainless Steel Cable Glands

For clients working in more demanding environments, stainless steel cable glands are typically selected due to their durability, strength, and ability to resist corrosion, along with their high-performance characteristics.

  • Corrosion resistance: Stainless steel cable glands are resistant to water, various chemicals, and severe weather conditions.
  • Extended service life: Stainless steel cable glands tend to last much longer than brass ones.
  • High-temperature capabilities: Stainless steel cable glands can sustain extreme temperature conditions, making them suitable for high-temperature applications.

Thread Types Of Metal Cable Glands

Metal cable glands are available in a variety of different thread types to accommodate diverse installation requirements. The most commonly used thread types for making connections are:

📏
Metric threads: Commonly used globally outside of North America, adhering to ISO standards.
🔩
NPT threads: Ideal for high-pressure applications and widely used in North America.
🌍
PG and G (BSP) threads: Used for specific industrial applications or regions.

To identify the appropriate thread type, refer to local building codes or the installation environment to ensure compliance and compatibility with your equipment.

Explosion-Proof and High-Temperature Options

For specialized environments like chemical plants, oil refineries, and gas industries, explosion-proof and high-temperature cable glands are recommended. These cable glands are made with durable materials designed to resist high pressures and extreme temperatures, thereby minimizing safety risks. Ensure that the selected cable gland is compatible with your equipment and meets safety standards for your application.

How to Select the Right Size Metal Cable Gland

Choosing the right size metal cable gland is critical to ensuring a secure connection. Here is a checklist to help you:

Determine the diameter of the cables you are using.
Identify the number of cables that need to pass through the gland.
Consider additional features such as strain relief or sealing properties.
Refer to the manufacturer’s sizing charts to ensure compatibility.

Frequently Asked Questions

Are there any thread types available for metallic cable glands?

Yes! There are many kinds of thread types available for metal cable glands, such as Metric threads, NPT threads, PG threads, and G (BSP) threads to comply with regional and industrial requirements.

What is the IP rating for industrial metal cable glands?

Most industrial metal cable glands have an IP68 rating, denoting maximum protection against dust and water ingress, though some may have lower ratings based on their design and application.

How do I know what size of cable gland will be right for my application?

The proper size cable gland for your application depends on the cable diameter, the number of cables to be used, and the environmental conditions. Manufacturers' sizing charts can assist in determining the correct specifications.

How are brass metal cable glands different from stainless steel metal cable glands?

Brass cable glands are good electrical conductors and cost-effective, making them ideal for general use. Stainless steel cable glands, on the other hand, offer greater strength and corrosion resistance, making them suitable for demanding environments.

Is it safe to use metal cable glands in an explosive environment?

Yes! Explosion-proof metal cable glands are designed to prevent the ignition of gases and combustible materials, meeting strict safety standards for hazardous locations.

Benefits of Using a Metal Cable Gland Manufacturer in China

China is now the world's largest manufacturer of metal cable glands. Working with a good manufacturer offers a balance of competitive pricing, high quality, and swift delivery. Many manufacturers in China also provide customized products for specific industrial applications, adhering to international standards like RoHS and ISO certifications.

When sourcing IP68 metal cable glands or specialized types like explosion-proof, high-temperature, or marine-grade options, ensure your supplier provides clear specifications, technical support, and post-purchase service.

Summary

Metal cable glands are fundamental components in industrial systems, offering maximum protection, reliability, and performance in extreme conditions. Selecting the appropriate type, size, and material is key to enhancing your system’s efficiency and safety. By familiarizing yourself with the range of metal cable glands available, you can make smarter decisions for your specific application needs.
