Waterproof Cable Gland and Armored Cable Gland the Difference
If you’re in the business of protecting cables, you know just how crucial a good Waterproof cable gland is. Think of cable glands as the unsung heroes that keep your cabling safe from water, dust, and mechanical damage. Especially in harsh industrial settings, choosing the right type of cable gland can make or break your installation.
Today, we’re diving into the world of Waterproof Brass Cable Gland and exploring one common question asked by many: What is the difference between armored cable glands and standard waterproof cable glands? Whether you’re specifying products for heavy industry or standard electrical enclosures, this guide will help you understand these two types, how they work, and which one fits your needs best.
What Is a Waterproof Cable Gland?
Before comparing different types, let’s get the basics down.
A waterproof cable gland is a device designed to secure and seal the end of a cable where it enters an enclosure, protecting the internal equipment from dust, dirt, and—most importantly—water. These glands ensure the cable remains fixed firmly, preventing strain and damage.
Key Features of Waterproof Cable Gland:
- Made from materials like brass, stainless steel, or nylon.
- Designed to meet IP protection ratings such as IP66, IP67, or IP68, which indicate resistance levels against solids and liquids.
- Used widely in electrical, telecommunication, and industrial applications.
For example, a cable gland rated IP68 can withstand immersion in water beyond 1 meter depth, making it perfect for outdoor or underwater installations.
Feature | Description |
---|---|
Material | Brass, Stainless Steel, Nylon |
Protection Rating | IP66, IP67, IP68 |
Function | Secure cable, seal entry point, prevent leaks |
Applications | Industrial, marine, telecom, outdoor environments |

Waterproof Cable Gland Working Principle
How exactly does a waterproof cable gland keep water out? Here is the scoop:
The waterproof cable gland uses a combination of mechanical clamping and sealing components to prevent liquid ingress. Here’s the typical setup and workflow:
- Outer Body: Usually metal or high-grade plastic, provides mechanical strength.
- Sealing Rings/Grommets: Made of rubber or elastomer materials like neoprene; these form a tight seal around the cable.
- Locknuts or Compression Mechanisms: Tighten the seal and hold the cable firmly in place.
When assembled, the gland compresses around the cable sheath, blocking off water paths and ensuring an airtight seal against dust and moisture.

Factors Impacting Waterproof Performance:
- Quality of seal material (rubber type, hardness)
- Tightness of the compression ring or nut
- Proper cable size and gland compatibility
- Use of lubricants for better sealing and ease of assembly
Common waterproof ratings like IP66 prevent jet water ingress, IP67 withstand full immersion up to 1m for 30 mins, and IP68 allows prolonged underwater exposure. These ratings ensure your cables stay protected in almost every condition.
Component | Role in Waterproofing |
---|---|
Outer Body | Structural strength, mechanical protection |
Sealing Ring | Primary water barrier around cable |
Compression Nut | Applies pressure to maintain seal |

Features of Standard Waterproof Cable Gland
Standard waterproof cable glands are designed for cables without armor.
- They focus mainly on sealing cable entries to keep out water and dust.
- Materials used are typically durable plastic or brass for corrosion resistance.
- Suitable for indoor and outdoor use where moderate mechanical strain is expected.
- These glands are easier to install and cost-effective for general applications.
Aspect | Description |
---|---|
Sealing | Rubber grommets provide water-tight seal |
Mechanical Grip | Compression nut holds cable but no armor clamp |
Materials | Nylon, brass, stainless steel |
Applications | Telecommunications, lighting, control panels |
Standard glands are widely used for industrial waterproof cable glands, offering a good balance of protection and cost.

Armored Cable Gland: Features and Applications
When cables are armored, they get an additional layer of mechanical protection, usually steel wire or tape wrapping. This armor protects cables from physical damage in rough environments like construction sites or industrial plants.
The armored cable gland is specifically designed to accommodate this armored layer. Unlike standard cable glands, these have special armor clamps or cones that grip and transfer mechanical load from the cable to the gland and enclosure.
Advantages of Armored Cable Gland:
- Superior mechanical retention and protection.
- Maintain electrical continuity (bonding) via armor.
- Ideal for hazardous areas, heavy machinery, and outdoor installations.
- Often compliant with explosion-proof standards.
Feature | Armored Cable Gland | Standard Waterproof Cable Gland |
---|---|---|
Cable Type | Steel wire armored or tape armored cable | Non-armored cables |
Mechanical Protection | High mechanical retention and cable protection | Basic strain relief |
Electrical Bonding | Provides armor bonding for grounding | Generally no electrical bonding |
Use Cases | Heavy industry, mining, oil and gas | General electrical and data cabling |
Cost | Higher due to complex structure | More economical |
Armored Cable Gland Working Principle
Armored cable glands combine the sealing function of standard glands with mechanical armor clamping.
- The gland body houses a cone or clamp specifically designed to lock the steel armor wire tightly.
- Upon tightening, the clamp compresses the armor against the gland, transferring mechanical loads and preventing cable pullout.
- Simultaneously, seals prevent water ingress, maintaining waterproof performance.
This dual function—mechanical protection plus waterproof sealing—is key in harsh or potentially explosive environments.
Unlike standard glands, armored glands must offer reliable conductivity for grounding through the armor layer, adding a safety layer to many industrial electrical systems.
Step | Description |
---|---|
Armor Clamping | Clamp tightens around armor wires for retention |
Seal Compression | Seals around cable prevent water and dust ingress |
Electrical Bonding | Armor is bonded to the cable gland for grounding |

Key Differences: Armored vs. Standard Waterproof Cable Gland
Let’s summarize the key differences between these two core types to help you decide:
Factor | Armored Cable Gland | Standard Waterproof Cable Gland |
---|---|---|
Mechanical Protection | High, clamps armor wire | Moderate, grips cable sheath only |
Electrical Bonding | Yes, armor bonding included | No electrical bonding |
Use Environment | Heavy industrial, mining, oil and gas | General outdoor and indoor waterproofing |
Water Protection | IP66, IP67, IP68 depending on seal | IP66, IP67, IP68 available |
Cost | Generally higher | More economical |
If your installation involves armored cables or extreme mechanical stress, armored cable glands are the way to go. For less demanding applications, standard waterproof cable glands do the job well while saving costs.
Choosing the Right Waterproof Cable Gland
Selecting a cable gland comes down to understanding the specifics of your application. Here’s a quick checklist:
- Cable type: armored or non-armored?
- Cable diameter: ensure compatibility with gland size.
- Environmental factors: Will it face water immersion? Dust? Chemicals?
- Required IP rating: IP66 vs IP67 vs IP68.
- Material needs: brass for corrosion resistance, nylon for cost efficiency.
- Compliance: Especially for hazardous areas (ATEX, UL, CE).
Consideration | Why It Matters |
---|---|
Cable Compatibility | Proper fit ensures effective sealing & retention |
Environmental Rating | Determines waterproof and dustproof capability |
Mechanical Requirements | Armor clamp needed for steel armored cables |
Material Durability | Corrosion resistance for marine or chemical exposure |
