Ensure that the outer sheath diameter of the designated cable falls within the middle of the "Recommended Cable Range". Tightening the gland forces the internal sealing claw and washer (typically made of premium NBR or EPDM) to compress firmly around the cable, providing an IP68-certified dust-proof and waterproof seal while relieving mechanical strain. Utilizing a size outside the specification compromises the ingress protection rating.

Our facility is fully certified by world-class regulatory authorities, ensuring our Pg, Metric, and NPT cable glands meet strict global engineering requirements.
Our high-performance Pg cable glands are engineered to withstand the harshest environments across dynamic high-tech sectors globally.
Cable glands are critical for new energy vehicles (NEVs), serving as essential components to manage and protect cables in high-voltage systems, battery packs, motor controllers, charging interfaces, and other core electrical units. Engineered to withstand extreme temperatures, vibration, moisture, and chemical exposure, they ensure reliable sealing, prevent dust/water ingress, and maintain insulation integrity to avoid electrical hazards. By securing and routing power, signal, and communication cables, they enhance the safety, stability, durability, and performance consistency of the vehicle’s electrical system. Compliant with automotive industry standards, high-quality cable glands help NEVs meet strict safety and reliability requirements, making them indispensable for electric cars, hybrid vehicles, and other new energy mobility solutions.
Cable glands are essential for robotics, managing and protecting power, signal, and data cables in industrial robots, cobots, AMRs, and more. Adapted to dynamic movements, harsh industrial environments (dust, coolant, mechanical stress), they prevent tangling, abrasion, and disconnection while ensuring IP68-rated sealing. By safeguarding electrical connections and reducing cable wear, they enhance robotic operational stability, precision, and service life. Compatible with various cable sizes and compliant with IEC/UL standards, they are foundational for reliable robotic systems.
Cable glands are vital for onshore/offshore wind power systems (turbines, substations, tower bases), protecting power/control/signal cables. Engineered to resist salt fog, extreme temps (-52℃ to 90℃), vibration, and UV, they offer IP68 sealing, explosion-proof performance, and EMC shielding. Made of durable EPDM rubber or 316L stainless steel or brass , they prevent cable abrasion/displacement and electrical hazards, ensuring long-term operational stability and safety.
Cable glands are key protective components in rail transit systems, widely used in rolling stock, substations, tunnels, and equipment rooms of metro, high-speed rail, and intercity rail. They secure and protect power, control, and signal cables. Adapted to harsh operating conditions, they feature an IP68 protection rating, resisting moisture, dust, and rodent damage, while withstanding extreme temperatures from -40℃ to 90℃ and continuous vibration. They are offering explosion-proof and sealing performance to prevent cable abrasion, signal interference, and fire spread. Their modular design supports future capacity expansion, extends the service life of cables and equipment, and ensures the long-term safe and stable operation of rail transit systems.
