Our core explosion-proof cable gland series for flexible conduit systems β designed for hazardous area installations with full international certifications and robust sealing performance.
An Ex Cable Gland for Flexible Conduit Assemblies is a specialized cable entry device engineered to maintain the integrity of explosion-proof enclosures while accommodating the routing of electrical cables through flexible metallic or non-metallic conduit systems. The term "Ex" refers to equipment designed for use in explosive atmospheres, in accordance with international standards such as ATEX, IECEx, and UL/NEC requirements.
Unlike standard cable glands, Ex-rated flexible conduit cable glands must simultaneously achieve multiple critical functions: provide a secure mechanical connection between the flexible conduit and the enclosure, maintain a certified flameproof or increased-safety barrier, deliver high-level ingress protection (IP66/IP68), and ensure reliable strain relief under dynamic industrial conditions.
These glands are typically manufactured from premium materials including nickel-plated brass, 304/316L stainless steel, and high-grade reinforced nylon β each selected to match specific environmental demands such as corrosion resistance, temperature extremes, and chemical exposure.
Every Ex cable gland in our flexible conduit assembly series is engineered to exceed international safety and performance standards, combining precision manufacturing with advanced materials science.
Fully certified to ATEX Directive 2014/34/EU and IECEx standards for use in Zone 1 and Zone 2 hazardous areas. Flameproof (Ex d), increased safety (Ex e), and combined protection types available to suit diverse installation requirements.
Rated IP68 for continuous submersion protection, ensuring complete dust exclusion and water ingress prevention. Ideal for offshore platforms, underground installations, and washdown environments where moisture intrusion poses critical risks.
Engineered to accept metallic and non-metallic flexible conduits across standard metric, NPT, and PG thread profiles. The locking mechanism provides 360Β° gripping action, ensuring conduit retention even under high vibration and thermal cycling.
Available in nickel-plated brass for standard industrial environments, 316L stainless steel for marine and chemical applications, and reinforced nylon for lightweight, corrosion-free installations. Each material is rigorously tested for temperature and chemical resistance.
Designed to perform reliably from -60Β°C to +200Β°C depending on material selection and sealing compound. High-performance EPDM and silicone sealing elements maintain compression set resistance across extreme thermal cycles common in industrial process environments.
Optimized thread geometry and pre-fitted sealing components enable rapid, tool-free assembly in the field. Integrated earthing tags and EMC shielding termination options are available for advanced electrical installations requiring bonding continuity.
From offshore oil & gas platforms in the North Sea to petrochemical refineries in the Middle East, from underground mining operations in Australia to pharmaceutical manufacturing plants across Europe β Hoonsun's Ex cable glands for flexible conduit assemblies are the specified choice of engineers and procurement professionals who demand certified safety, proven durability, and consistent supply chain reliability. Our products have been honored to supply critical components for major national defense and marine projects, including the Aircraft Carrier "Liaoning."
The global Ex cable gland market for flexible conduit assemblies is experiencing significant transformation driven by evolving safety regulations, industrial digitalization, and the rapid expansion of hazardous-area industries worldwide.
The global hazardous area equipment market is projected to surpass USD 12 billion by 2028, growing at a CAGR of over 6%. Increasing investments in oil & gas infrastructure, chemical processing, and mining operations across Asia-Pacific, the Middle East, and Latin America are driving unprecedented demand for certified Ex cable gland solutions for flexible conduit systems.
Regulatory bodies worldwide are tightening explosion-proof equipment standards. The harmonization of ATEX and IECEx frameworks, combined with updated NEC/CEC requirements in North America, is compelling industrial operators to upgrade legacy cable management systems to fully certified Ex flexible conduit assemblies β creating a significant replacement market.
Industry 4.0 and IIoT deployments in hazardous environments require increasingly dense cable routing with integrated EMC shielding and data cable management. Ex cable glands for flexible conduit are evolving to accommodate multi-cable, hybrid power-data configurations, with built-in grounding and shielding termination becoming standard specification requirements.
The rapid growth of offshore wind farms, solar energy plants, hydrogen production facilities, and EV battery manufacturing introduces new categories of hazardous area installations. These emerging sectors require Ex-rated flexible conduit cable glands capable of handling both power and signal cables in environments with flammable gas, dust, or chemical vapor hazards.
Manufacturers are investing in high-performance polymers, advanced surface treatments, and precision CNC machining to produce Ex cable glands with superior corrosion resistance, reduced weight, and extended service life. Automated production lines and AI-assisted quality inspection are elevating product consistency to levels previously achievable only with hand-crafted precision.
Global supply chain disruptions have accelerated the shift toward qualified regional manufacturers and long-term strategic supply agreements. Industrial buyers are increasingly partnering directly with certified Chinese manufacturers like Hoonsun β combining cost efficiency, production scale, and international certification compliance β to secure reliable supply of Ex flexible conduit cable glands.
Ex cable glands for flexible conduit assemblies serve as critical safety components across a wide spectrum of hazardous and demanding industrial environments. Understanding these applications helps engineers specify the right product for every installation.
In Zone 1 and Zone 2 classified areas of refineries, platforms, and LNG terminals, Ex cable glands for flexible conduit provide the critical interface between rigid cable trays and motor terminal boxes, junction boxes, and instrumentation enclosures β maintaining flameproof integrity while accommodating thermal movement and vibration.
Chemical plants handling flammable solvents and pharmaceutical facilities with solvent-based processes require Ex flexible conduit glands in 316L stainless steel or PTFE-coated variants to resist aggressive chemical attack while maintaining Zone 1 certification. Clean-room compatible designs ensure compliance with GMP standards.
Mining environments combine explosive methane atmospheres with extreme mechanical stress, water ingress, and abrasive dust. Ex cable glands for flexible metallic conduit provide the robust, IP68-rated, Ex d certified connection points required for mining machinery, ventilation systems, and underground communications infrastructure.
Offshore drilling platforms, FPSOs, and naval vessels demand cable gland solutions that combine explosion-proof certification with marine-grade corrosion resistance. Our TH Standard Type marine cable glands, UL-listed and IP68-rated, are engineered for continuous saltwater exposure, meeting the most demanding marine classification society requirements.
Offshore wind turbine nacelles and towers contain transformer rooms and battery storage areas classified as hazardous zones. Ex flexible conduit cable glands enable safe, watertight cable routing through nacelle walls and tower penetrations, with stainless steel construction providing the 25+ year service life demanded by offshore wind operators.
Flour mills, sugar refineries, and distilleries present Zone 22 dust explosion hazards requiring Ex-rated cable management. Nylon reinforced Ex cable glands for flexible conduit offer food-safe, non-sparking cable entry solutions that withstand high-pressure washdown while maintaining certified protection against combustible dust ignition.
