Cable Gland Components ensure secure, sealed cable entries into enclosures, vital for industrial safety and performance. This 2026 guide details every key part with updated specs, materials, and applications for engineers tackling automation, renewables, and harsh environments.
Core Components Overview
Cable glands assemble from precision-engineered parts like the body, seals, and clamping rings. These create IP66-IP68 protection while providing strain relief and grounding per IEC 62444 standards.
Modular designs in 2026 speed installation by 35%, using brass or stainless steel for corrosion resistance. Components match cable OD, armor type, and environmental demands.
Primary Parts and Functions
Gland Body
Houses seals and threads into panels; nickel-plated brass withstands marine exposure.
Seals (Inner/Outer)
Compress sheath for watertight seals; EPDM handles -50°C to 150°C and chemicals.
Locknut and Washer
Secures assembly; serrated versions resist vibration up to 10G.
Essential for all glands; select per BS 6121 specs.
Seals Deep Dive
Single-compression seals suit unarmored PVC cables with one outer ring. Double-compression adds inner seals for armored types, boosting IP68 at 10 bar.
2026 LSZH seals cut smoke in fires; displacement seals auto-fit oval cables ±20%.
O-rings provide backup sealing, resisting oils in automotive apps.
Prevents 90% of ingress failures.
Clamping and Armor Components
Cones or claws grip wire armor (SWA), providing 400N pull strength. Earth tags bond braid to enclosure ground, NEC-compliant.
Universal cones fit multiple armors, reducing stock 40%. Compression rings secure flexible braids.
Thread and Entry Parts
Metric M16-M63 threads dominate; PG/NPT adaptors convert sizes. Entry threads guide cables; flat washers distribute torque.
Ensures perfect fit; torque M25 at 30Nm.
Grounding Accessories
Earth continuity plates (ECP) for multi-core; tags for single. Nickel-plated brass cuts resistance <0.1Ω.
Mandatory in hazardous areas per ATEX 2026.
Mounting Hardware
Serrated washers grip thin panels; check nuts pre-fix orientation. Blanking plugs seal spares, maintaining IP.
Material Guide 2026
Brass: Conductive, 85% IACS. SS316L: Pitting resistant (PREN 24+). Nylon PA66: Lightweight, 50% cheaper.
Electroless nickel plating boosts life 4x in saltwater. Bio-polymers reduce CO2 25%.
Matches ISO 12944 environments.
Sizing Charts and Selection
Size by cable OD min-max; charts cross-reference cores vs. area (1.5-1000mm²).
Example: 4-core 25mm² = M32 gland.
Step-by-step: Measure OD/armor, check tolerance (±10%), verify hole.
Assembly Instructions
