What is Cable Gland? How Does It Work?
A Cable Gland is a mechanical device used to secure the end of an electrical cable to equipment. It provides strain relief and creates a seal that protects against dust, moisture, and mechanical stress. Commonly found in control cabinets, junction boxes, and outdoor electrical systems, it ensures electrical connections remain safe and durable.
How Does It Work:
When a cable passes through an enclosure wall, it must be secured so that no external elements enter the cabinet. The Cable Gland consists of a nut, body, sealing ring, and compression cap. First, the gland is inserted through a pre-drilled hole in the enclosure. The cable is then fed through the gland body. When the compression cap is tightened, it compresses the sealing ring around the cable, creating a waterproof and dustproof seal. This prevents tension from reaching internal connections, protecting cables from pulling, twisting, or vibration damage.
For hazardous environments, specialized versions like Ex Cable Glands use metal bodies and explosion-proof seals to prevent sparks. Waterproof Cable Glands with IP68 ratings are used outdoors or in wet locations. Depending on the threading standard (PG, NPT, or metric), Cable Glands fit different regional requirements.
In summary, Cable Glands work as both a mechanical anchor and environmental seal for cables, essential for maintaining electrical safety, reducing maintenance costs, and extending equipment lifespan.
What are the Benefits of Cable Gland?
Prevents dust and water ingress, ensuring long-lasting cable protection.
Reduces mechanical stress on cables, preventing damage and extending lifespan.
Simplifies installation and maintenance for safer, faster assembly.

FAQ of Cable Gland
How do I choose the right Cable Gland size?
Choosing the correct size depends on the outer diameter (OD) of your cable and the thread type required by your installation (PG, NPT, or Metric). The gland’s clamping range must tightly fit your cable jacket to ensure a proper seal. At Linkwellelectrics, we provide detailed size charts and expert guidance to help you select the correct model for your application.
Are Cable Glands waterproof?
Yes. Our IP68-rated cable glands provide full protection against water and dust ingress. They are suitable for outdoor, marine, and telecom applications where moisture protection is critical. The sealing rings and precision threads ensure long-term reliability even under harsh environmental conditions.
What materials are available and how to choose?
We manufacture Cable Glands in nylon, plastic, nickel-plated brass, and stainless steel.
Nylon / Plastic: Lightweight, corrosion-resistant, ideal for general electrical panels.
Brass: Strong, durable, and suited for industrial automation and machinery.
Stainless Steel: Perfect for outdoor, marine, or chemical environments requiring maximum corrosion resistance.
Our engineers can recommend the ideal material based on your operating environment.
How do I install a Cable Gland correctly?
Drill or verify the correct panel hole size.
Insert the gland body and secure it with the locknut.
Pass the cable through the gland.
Tighten the sealing nut to compress the rubber ring around the cable.
Always check torque specifications and confirm that the sealing ring is in place to maintain IP protection.
How do you guarantee product quality?
Every eyelet undergoes tensile strength, corrosion resistance, and dimensional precision tests under ISO-controlled conditions. We maintain traceable quality records and support third-party inspections for export orders to ensure consistent reliability.
Can you also supply the eyelet installation machines?
Yes. As a complete system supplier, we provide manual, electric, and pneumatic eyelet attaching machines that are compatible with our grommets. This allows you to streamline your production process — from eyelet manufacturing to installation — with stable quality and higher efficiency.
