Our core product line — precision-engineered sealed cable glands designed to deliver superior ingress protection and mechanical performance across all flexible conduit assembly applications.
A sealed cable gland for flexible conduit assemblies is a precision mechanical fitting engineered to provide a secure, watertight, and mechanically robust termination point where flexible conduit meets an electrical enclosure, junction box, panel, or equipment housing. Unlike standard cable glands that grip a cable directly, these specialized fittings are designed to interface seamlessly with flexible metallic conduit (FMC), liquid-tight flexible metallic conduit (LFMC), flexible non-metallic conduit (FNMC), and corrugated conduit systems.
The sealing mechanism — typically achieved through precision-molded elastomeric seals, EPDM or NBR O-rings, and compression locknuts — ensures ingress protection ratings up to IP68 (1.5m / 30 min), preventing the entry of dust, moisture, oils, and corrosive agents. This is critical in environments where cable routing must remain flexible while the entry point into sensitive equipment must remain absolutely sealed.
Modern sealed cable glands for flexible conduit are available in brass, nickel-plated brass, stainless steel (SS304/SS316), and high-performance nylon (PA66), covering thread standards including PG, Metric (M), NPT, and G/PF — making them universally adaptable across global industrial standards.
IP68 certification means complete dust-tight protection and continuous submersion capability. For flexible conduit assemblies in outdoor power infrastructure, marine environments, or underground cable management, IP68 sealed glands are not optional — they are the engineering baseline for long-term reliability and safety compliance.
Every sealed cable gland in our flexible conduit assembly range is built around four non-negotiable performance pillars.
Multi-layer elastomeric compression seals ensure zero water ingress even under sustained submersion, protecting sensitive wiring from moisture and condensation.
Metallic shielded variants provide 360° continuous grounding contact, suppressing electromagnetic interference in sensitive control and communication cable runs.
EX-rated glands certified to ATEX and IECEx standards prevent ignition sources from propagating through conduit entries in Zone 1 and Zone 2 hazardous areas.
Available in PG, Metric, NPT, and BSP thread forms, enabling direct integration with global equipment standards without adapters or modifications.
Sealed cable glands for flexible conduit assemblies are not a commodity product — they are a precision safety component. Here is how they perform across the most demanding industrial sectors.
Photovoltaic inverter stations, combiner boxes, and string monitoring units require flexible conduit entries that maintain IP68 sealing integrity across UV exposure, thermal cycling (−40°C to +120°C), and vibration from wind loading. Sealed glands with UV-stabilized nylon or stainless steel bodies are specified for all outdoor PV plant cable management systems.
EN 50155-compliant rail vehicles demand cable entries that resist vibration, shock, humidity, and cleaning chemicals. Sealed cable glands for flexible conduit assemblies provide the anti-vibration strain relief and IP67/IP68 protection required at every cable penetration point — from traction control panels to passenger information systems.
Saltwater corrosion, wave impact, and continuous humidity demand stainless steel SS316 sealed glands with EPDM seals rated for continuous immersion. Flexible conduit assemblies on deck equipment, navigation systems, and engine room cable routes rely on IP68 glands to prevent catastrophic electrical failures at sea.
Robot arms and CNC machining centers use flexible metallic conduit to protect servo motor cables from coolant spray, swarf, and mechanical abrasion. The conduit-to-enclosure interface must maintain IP65+ sealing while accommodating continuous flexing and rotational movement — a role uniquely suited to precision sealed cable glands.
ATEX Zone 1 and Zone 2 classified areas in refineries, chemical plants, and offshore platforms require Ex-rated sealed cable glands that prevent explosive gas ignition. EX3 and EX5 certified glands with flame-path barriers and IP68 sealing are mandatory at all conduit terminations in hazardous area electrical installations.
Excavators, cranes, and mining equipment operate in environments with extreme dust, mud, vibration, and hydraulic oil contamination. Flexible conduit assemblies terminated with IP68 sealed glands protect engine control harnesses and sensor cables from ingress that would cause costly electronic failures in remote operating locations.
The global cable gland market is undergoing significant transformation driven by electrification megatrends, tightening safety regulations, and the rise of smart manufacturing.
The global cable gland market was valued at over USD 1.2 billion in 2023 and is projected to grow at a CAGR exceeding 6.5% through 2030. The primary drivers are the global energy transition (solar, wind, EV charging infrastructure), expanding industrial automation, and mandatory upgrades to aging electrical infrastructure in North America, Europe, and Southeast Asia. Sealed cable glands for flexible conduit assemblies represent the fastest-growing sub-segment, fueled by the shift toward liquid-tight and EMC-shielded conduit systems in smart factories.
As manufacturing facilities adopt IIoT sensors, collaborative robots, and edge computing nodes, the density of cable penetrations requiring sealed flexible conduit terminations has increased dramatically. Modern production lines require glands that not only seal but also provide EMI suppression for data integrity in high-frequency communication cables — driving demand for EMC-rated sealed cable glands with 360° shielding continuity across the full conduit assembly.
Regulatory frameworks are converging globally. The NEC (NFPA 70) in North America, IEC 60079 for hazardous areas, EN 50262 in Europe, and AS/NZS standards in Oceania are all raising the bar for conduit sealing integrity. Manufacturers and contractors now require dual-certified products (e.g., UL + IP68, or ATEX + CE + RoHS) to simplify compliance across multi-regional projects — a requirement that Hoonsun's product range directly addresses.
The industry is moving beyond standard brass toward advanced material combinations: high-performance PA66 GF nylon for weight reduction in EV and aerospace applications; SS316L stainless steel for corrosive marine and chemical environments; and halogen-free, RoHS-compliant elastomers for green building and consumer electronics applications. Simultaneously, manufacturers are investing in automated CNC machining and precision injection molding to achieve tighter dimensional tolerances and reduce material waste in high-volume production.
