In modern electrical and industrial installations, safety, durability, and precision matter more than ever. When it comes to cable protection and secure connections, Metal Cable Glands play a critical role. These small yet essential components are the foundation of safe wiring systems across industries such as manufacturing, energy, construction, and telecommunications.
As someone with decades of hands-on experience in industrial equipment and electrical accessories, I can say with confidence that choosing the right cable gland is not only about meeting technical requirements—it's about ensuring long-term reliability and minimizing risks. This is why more engineers, contractors, and industrial buyers are turning to Metal Cable Glands for demanding applications.
Wenzhou Zhechi Electric Co., Ltd., a trusted manufacturer in this field, has been consistently delivering products that meet strict international standards, providing professional solutions for global clients.
When selecting cable glands, one of the most common questions is whether to use metal or plastic. While plastic may be cost-effective for light-duty indoor use, Metal Cable Glands offer significant advantages in terms of:
Durability: Resistant to impact, corrosion, and extreme weather conditions.
Safety: Provides superior grounding and shielding performance.
Temperature Resistance: Operates effectively in high and low temperature ranges.
Mechanical Strength: Ideal for heavy-duty and outdoor installations.
In industries where reliability cannot be compromised, metal is often the only suitable choice.

This professional specification sheet demonstrates why engineers worldwide trust Metal Cable Glands to ensure system reliability.
The versatility of Metal Cable Glands makes them indispensable across industries. Some notable use cases include:
Industrial Machinery – Protecting cables from vibration, oil, and dust.
Outdoor Lighting Systems – Withstanding rain, UV exposure, and temperature fluctuations.
Automation and Control Systems – Providing secure strain relief for precision instruments.
Energy & Power Plants – Ensuring grounding and shielding in high-voltage environments.
Telecommunications – Delivering stable and interference-free cable connections.
Marine & Offshore Applications – Offering corrosion resistance against seawater and salty air.
Wherever cables enter an enclosure, panel, or device, a reliable Metal Cable Gland is essential.
Let's summarize the key benefits:
✅ Long-lasting performance in harsh environments
✅ Excellent sealing against water, dust, and chemicals
✅ High resistance to mechanical impact and vibration
✅ Enhanced safety through grounding and EMI protection
✅ Wide range of sizes and thread standards available
✅ Compliance with international safety standards
These advantages directly translate to lower maintenance costs and increased operational efficiency.
Even the best products require correct installation. Here are simple but effective tips for using Metal Cable Glands:
Choose the right size: Ensure the clamping range matches the cable diameter.
Check sealing material: NBR is suitable for standard use, while silicone or EPDM handles extreme environments.
Match thread types: Always confirm whether your equipment requires metric, PG, or NPT threads.
Tighten carefully: Over-tightening may damage the sealing ring, while under-tightening compromises protection.
Inspect regularly: For critical installations, periodic checks maintain long-term reliability.
Following these guidelines ensures the gland delivers maximum performance throughout its service life.
Q1: What is a Metal Cable Gland used for?
A1: A Metal Cable Gland is designed to securely attach and seal cables into electrical equipment, enclosures, or machinery. It provides strain relief, protects against dust and water ingress, and in some cases ensures grounding and electromagnetic shielding.
Q2: Are Metal Cable Glands waterproof?
A2: Yes, high-quality models like those from Wenzhou Zhechi Electric Co., Ltd. are rated IP68, meaning they are dust-tight and can withstand immersion in water under defined pressure. This makes them suitable for both indoor and outdoor applications.
Q3: How do I choose the right size of Metal Cable Gland?
A3: The correct size depends on the cable's outer diameter and the gland's clamping range. Always refer to the manufacturer's specification table. For example, if your cable diameter is 12 mm, you should select a gland with a clamping range of around 10–14 mm.
Q4: Can Metal Cable Glands resist corrosion?
A4: Absolutely. Nickel-plated brass and stainless-steel cable glands offer high resistance to corrosion, making them suitable for outdoor, marine, and chemical environments where long-term durability is required.
