Nickel-Plated Brass Cable Gland
Nickel-plated brass cable glands provide secure cable entry, strain relief, and environmental protection for electrical enclosures and machinery. Built from high-grade solid brass and finished with a corrosion-resistant nickel layer, these fittings maintain electrical conductivity while withstanding harsh industrial environments. Each unit features a multi-element clamping and sealing structure that secures the cable and prevents liquid or dust ingress without damaging the outer sheath.
Precision-machined brass cable glands engineered for secure mechanical cable retention, earth continuity, and reliable environmental sealing in industrial enclosures.
Product Overview
Nickel-plated brass cable glands provide secure cable entry, strain relief, and environmental protection for electrical enclosures and machinery. Built from high-grade solid brass and finished with a corrosion-resistant nickel layer, these fittings maintain electrical conductivity while withstanding harsh industrial environments. Each unit features a multi-element clamping and sealing structure that secures the cable and prevents liquid or dust ingress without damaging the outer sheath.
Key Features
Material Composition: Body, locknut, and sealing nut machined from solid HPb59-1 or CW614N brass, offering high mechanical strength and impact resistance.
Surface Treatment: Electroplated nickel coating (3 to 5 microns) provides corrosion resistance against moisture, salt spray, and industrial chemicals.
Sealing Structure: Nitrile rubber (NBR) or silicone sealing insert and O-ring deliver an IP68 waterproof and dustproof rating (up to 5 bar pressure resistance).
Clamping Mechanism: Polyamide (PA6) claw design distributes mechanical gripping force evenly around the cable circumference, providing high pull-out resistance and preventing cable twist.

Plating Adhesion Test: Cross-hatch and salt spray testing (ASTM B117, 96-hour neutral salt spray) to ensure nickel coating integrity.
Seal Integrity Test: Pneumatic pressure decay testing and submersion water testing to verify IP68 sealing performance under operational pressure.
Material Traceability: Mill test certificates (MTC) and regional compliance documentation available upon request.
CAD & Technical Downloads: Downloadable 2D/3D CAD models (STEP/IGES) and comprehensive PDF data sheets are available to assist design and panel-building integration.
Frequently Asked Questions
Q: How do I select the correct thread size for my enclosure knockout?
A: Match the knockout hole diameter to the thread designation (e.g., an M20x1.5 gland requires a 20.5 mm hole). Refer to the technical drawing for exact panel clearance hole dimensions.
Q: What is the exact cable outer diameter range for an M20 gland?
A: Standard M20x1.5 brass cable glands accommodate cable outer diameters from 6.0 mm to 12.0 mm. Heavy-duty or multi-hole inserts are available for alternative wire sizes.
Q: Can these glands withstand continuous outdoor exposure?
A: Yes. The nickel-plated brass body and UV-resistant NBR/silicone seals prevent oxidation and material degradation in outdoor industrial environments.
Q: What is the minimum order quantity (MOQ) for standard sizes?
A: Standard sizes stocked in inventory have an MOQ of 100 pieces per size. Custom thread specifications or non-standard configurations require an MOQ of 1,000 pieces.
Q: What is the standard production lead time?
A: Stock items ship within 3 to 5 business days. OEM custom production runs require 15 to 25 business days depending on order volume and plating schedules.
Q: What quality documentation is included with shipments?
A: Each shipment includes a Certificate of Conformance (CoC), material test report, and dimensional inspection checklist upon request.
