A cable gland is a small but powerful component that helps electrical systems stay safe, clean, and secure. It seals cables where they enter equipment, stopping dust, water, and mechanical stress from causing damage. For industries where reliability matters, using the right nylon cable gland can make all the difference.
As a professional provider of connection and sealing solutions, HUNTEC delivers high-quality, high-performance cable glands trusted by international manufacturers and system integrators across automation, telecom, energy, and marine sectors.
A cable gland, also called a cable connector or entry device, is designed to fix, seal, and protect the cable entering an enclosure. It prevents twisting, pulling, and environmental contamination from affecting the internal wiring.
It’s not just a mechanical anchor. The gland also provides a sealed barrier that keeps water, dust, and other substances out. Whether you're running power cables in a factory or signal lines in a control panel, cable glands maintain performance and safety.
They are essential across many fields: energy systems, data centers, offshore equipment, and automation lines. Without them, equipment would be more prone to wear, failure, or even hazards.
Though compact in design, cable glands perform multiple functions:
Provide strain relief to cables to prevent pull-out failures.
Offer environmental sealing at the cable entry point.
Maintain enclosure ingress protection (IP) levels.
In some designs, provide grounding or shielding functions for EMC performance.
Once installed, the gland’s components grip the cable tightly. This grip supports the cable, reducing tension on connections. The seal blocks external elements from entering the equipment housing. Some glands offer double sealing for added protection.
When working in high-risk areas—such as outdoors or in damp, dusty spaces—using IP66/IP68-rated nylon cable glands ensures strong protection and long-term durability.
Single compression glands are used for small to medium-scale electrical installations. Double compression types provide extra sealing and are preferred in high-vibration or moisture-prone environments like processing plants or outdoor energy setups.
In environments with strong electromagnetic fields, EMC-compatible glands help protect data and control cables. These glands block interference and improve system stability.
Made to withstand salt spray, humidity, or direct water contact, these glands ensure that sensitive cables stay dry and operational. Many nylon cable glands with IP68 ratings fall under this category, offering protection even under temporary submersion.
These types reduce fire risk by resisting high temperatures and preventing flame propagation through cable paths. Often used in transportation and public infrastructure.

HUNTEC provides a full range of these solutions, ensuring every industry and project gets a fitting product. Whether sealing high-density control wires or high-power supply lines, our glands offer the right balance of flexibility, strength, and sealing power.
Material choice affects durability, protection, and cost. Each type has unique advantages:
| Material | Strengths | Common Environments |
|---|---|---|
| Nylon (Polyamide) | Flame-retardant, corrosion-proof, light | Telecom, indoor panels, marine systems |
| Brass | Rigid, conductive, resists corrosion | Automation, energy stations, control centers |
| Stainless Steel | High strength, heat-resistant, non-reactive | Petrochemicals, offshore, chemical handling |
| Aluminum | Lightweight, thermally conductive | HVAC, railways, electronics assembly |
| PVC | Cost-effective, basic sealing | Indoor consumer products |
Among them, nylon cable glands strike a great balance between affordability and performance. Their flame retardancy, IP68 sealing, and impact resistance make them ideal for both fixed and dynamic wiring.
Cable glands must fit the cable and the enclosure perfectly. Sizes are based on:
Thread diameter: e.g., M12 to M72
Cable outer diameter range: varies per model
Thread length and type: ISO Metric, PG, NPT, or BSP
Let’s take a look at HUNTEC’s RSKP-N series examples:
| Model | Thread Size | Thread Length | IP Rating | Cable Range |
|---|---|---|---|---|
| RSKP-N-M16F | M16 | 8mm | IP68 | 1.5–3mm |
| RSKP-N-M20C | M20 | 10mm | IP66/68 | 10–15mm |
| RSKP-N-M25B | M25 | 11mm | IP68 | 11–16mm |
| RSKP-N-M40 | M40 | 11mm | IP68 | 19–28mm |
This range supports both signal wires and thick power cables. Each size ensures the gland fits tightly, preventing leaks and strain.
Cable glands are everywhere—hidden but critical. Some core application areas include:
Industrial Automation: Manage bundles of sensors, actuators, and PLC wiring
Energy and Utilities: Secure power lines in transformers and substations
Marine and Offshore: Prevent water ingress in control cabinets
Smart Buildings: Organize and seal communication and power cables
Renewable Energy: Protect solar panel outputs and wind turbine wiring
Transportation Systems: Control fire spread and withstand vibrations
These environments demand protection from temperature changes, humidity, chemicals, mechanical stress, or electromagnetic interference. Long-tail search queries like “best cable glands for solar installation” or “flameproof cable glands for automation panels” reflect growing niche needs.
Buying the right cable gland isn’t only about size. Here’s what else you must check:
Cable type: Armored or unarmored
Cable diameter: Confirm fitting range
Environmental exposure: Moisture, chemicals, UV
Mounting panel design: Hole size, thread compatibility
Required certifications: UL, CE, RoHS, ATEX, etc.
Vibration or mechanical load: Need for strain relief or dual compression
For high-performance or hazardous sites, the protection level should always be verified—especially IP rating, flame resistance, and material durability.
