In today’s industrial field and outdoor equipment applications, waterproof cable gland have become a crucial component to ensure the safety and reliable operation of electrical devices. Whether it’s power control cabinets, outdoor lighting, or photovoltaic systems, secure and stable cable connections are fundamental to equipment performance. A high-quality waterproof cable gland not only fixes and seals the cable but also effectively prevents water and dust ingress, thereby extending equipment service life.
Are you struggling to find a waterproof cable gland that is both durable and efficient? This article will take you through the working principle and protection levels of waterproof cable glands to help you make the best purchasing decision.
Simply put, a waterproof cable gland is a sealing and fixing device used on cables to prevent water or dust from entering electrical equipment when cables pass through the enclosure. Its design provides tight clamping and sealing, suitable for various industrial applications.
Main Uses:
Though waterproof cable glands come in various designs, the core components typically include:
| Component | Function Description |
|---|---|
| Body | Connects the device and cable entry hole, stabilizing the entire assembly |
| Locknut | Used to tighten the sealing ring, ensuring seal integrity |
| Sealing Ring | Made of a flexible material, wraps around the cable to prevent moisture penetration |
| Clamping Claw | Firmly holds the cable to prevent slipping and pulling |
| Compression Nut | Further compresses the sealing ring and clamping claw to achieve dual sealing and fixation |
When the cable passes through the waterproof gland, tightening the compression nut compresses the clamping claw and sealing ring tightly around the cable, forming a tight seal. This mechanical compression prevents water and dust from entering the equipment housing, maintaining cable connection stability even in humid or dusty environments.
Imagine you’re tying your shoes tightly when it rains, preventing water from soaking inside. The waterproof cable gland acts like that “shoe lace,” protecting your cable from the “rain.”
Understanding protection levels (IP Ratings) is essential when selecting a waterproof cable gland. The IP rating measures the device’s protection against solid particles (like dust) and water.
| IP Rating | Dust Protection | Water Protection | Suitable Scenarios |
|---|---|---|---|
| IP65 | Dust tight | Protection against water jets from any direction | Outdoor equipment, water spray environments |
| IP66 | Dust tight | Protection against powerful water jets | Heavy-duty outdoor industrial environments |
| IP67 | Dust tight | Protection against temporary immersion (up to 1 meter, 30 mins) | Temporary underwater use, humid environments |
| IP68 | Dust tight | Protection against long-term immersion (depth over 1 meter, duration varies by manufacturer) | Underwater equipment, photovoltaic systems, extreme outdoor environments |
Selection Tip: If your equipment is exposed to long-term immersion or underwater use, an IP68 waterproof cable gland is the best choice.
Material greatly affects the performance of waterproof cable glands. Different materials are suitable for different environments:
| Material | Advantages | Suitable Environments |
|---|---|---|
| Metal (Stainless Steel, Brass) | Corrosion resistance, high-temperature resistance, strong mechanical strength | Industrial manufacturing, outdoor, heavy-load environments |
| Plastic (Nylon, PA) | Lightweight, chemical resistance, excellent insulation | Electronics, light load, indoor use |
| Brass | Good strength and conductivity | Electrical installation and general industrial use |
Common specifications include PG, M, NPT thread types, matching different installation needs.

Correct installation is key to ensuring waterproof effectiveness. Standard installation steps include:
Recommended routine maintenance includes regularly checking the sealing ring and replacing any worn parts to prevent moisture ingress.
| Maintenance Item | Frequency | Purpose |
|---|---|---|
| Sealing ring check | Every 6 months | Ensure no cracks or aging |
| Tighten fittings | Every 3 months | Prevent loosening that reduces waterproofing |
| Surface cleaning | Monthly | Prevent contamination of sealing parts |
When purchasing, pay close attention to the following parameters and certifications:
| Focus Point | Explanation |
|---|---|
| Certifications | UL, CE, and other certifications ensure product quality and safety |
| Protection Level | Choose an IP rating suitable for the actual operating environment |
| Size Matching | Ensure cable diameter matches gland size for proper sealing |
| Material | Choose material based on environmental factors such as corrosion and temperature |
| Explosion-proof | For hazardous areas, select glands that meet explosion-proof standards |

| Industry | Application Scenario | Recommended Protection Level & Material |
|---|---|---|
| Outdoor Lighting | Street lamps, landscape lights that require protection from rain and dust | IP67/IP68, corrosion-resistant metal material |
| Photovoltaic | Solar panel junction boxes exposed to sun and rain | IP68 waterproof, mixed plastic and metal materials |
| Power Control Cabinets | Factory distribution cabinets exposed to humid environments | IP65 and above, metal glands, multiple sealing layers |
Waterproof cable glands are not just connectors between cables and equipment; they serve as “gatekeepers” safeguarding industrial equipment for safe operation. Their tight sealing design and multiple protection levels ensure that environmental factors do not threaten electrical safety.
