Brass Cable Glands

Nickel-Plated Brass Cable Glands (Metric, PG, NPT & G Threads)

Heavy-duty industrial cable glands engineered for secure cable entry, mechanical strain relief, and IP68 environmental sealing in electrical enclosures and machinery. Precision-machined from solid brass with an electroplated nickel surface, offering robust resistance against mechanical stress, atmospheric oxidation, and chemical exposure in harsh indoor and outdoor installations.

Key Features

Alloy & Surface Protection:

Machined from solid brass stock (CuZn39Pb3 / H59) with a corrosion-resistant nickel-plated finish.

Progressive Clamping Design:

Features a nylon (PA6) clamping claw coupled with a dynamic chloroprene rubber (CR) sealing insert, delivering uniform 360-degree cable retention and high pull-out resistance without damaging the cable jacket.

Hermetic Enclosure Seal:

Includes a precision-grooved nitrile rubber (NBR) O-ring on the connection thread to prevent liquid and dust ingress at the panel mounting interface.

Ingress Protection:

Certified to IP68 (up to 10 bar water pressure) and IP69K-compatible variants available for high-pressure washdown environments.

Product Options

Base Materials:

Unplated brass, nickel-plated brass, and marine-grade stainless steel (AISI 304 / 316).

Thread Variations:

Extra-long connection threads designed for thick-walled control cabinets, fiberglass enclosures, or cast-iron junction boxes.

Specialized Inserts:

High-temperature silicone sealing inserts (endurance up to +180°C) and multi-hole inserts for routing multiple cables through a single entry point.

EMC Shielding Options:

Integrated contact spring designs for shielded cables, ensuring low-resistance electromagnetic compatibility (EMC) grounding.

Matching Hardware:

Brass locknuts, EMC earthing locknuts, and fiber or nylon thread sealing washers.

Applications

Industrial electrical control cabinets, switchgear, and PLC panels

Factory automation machinery, CNC centers, and robotics wiring harnesses

Outdoor distribution boxes, telecommunication shelters, and traffic signal controllers

Renewable energy solar inverter stations and wind turbine nacelles

Marine, offshore, and heavy transportation electrical systems

OEM & ODM Customization

Custom Machining:

Non-standard thread pitches, customized thread lengths, or proprietary thread profiles produced on multi-axis CNC lathes.

Dimensional Adaptations:

Tailored body geometries or specialized wrench flat dimensions to fit compact, space-constrained panel layouts.

Laser Marking:

Permanent laser-etching of client part numbers, batch traceability codes, or corporate logos directly onto the gland body or locknut.

Flexible Packaging:

Bulk industrial packaging, individual polybagging, or pre-assembled kiting (gland, locknut, and washer packaged as a single unit).

Quality Control & Manufacturing

Raw Material Spectrometry:

Direct chemical composition analysis performed on every incoming batch of brass rods to ensure compliance with alloy standards (CuZn39Pb3).

Dimensional & Thread Metrology:

100% profile inspection using optical comparators and calibrated GO/NOGO thread plug gauges to maintain strict tolerance control (ISO 6g / 6H).

Pressure & Sealing Verification:

Periodic hydrostatic and pneumatic burst and leakage testing conducted on sample lots to validate IP68 performance under operational stress.

Compliance Documentation:

Full material test certificates (EN 10204 3.1), RoHS compliance declarations, and REACH certificates available upon order confirmation.

Frequently Asked Questions

Q: How do I select the correct thread type and size for my application?

A: Identify whether your enclosure panel hole uses Metric, PG, or NPT standards. Verify the thread diameter and pitch using a thread pitch gauge. Match your cable's outer diameter to the specific clamping range specified in our technical specifications table.

Q: Can Metric and PG threaded glands be used interchangeably?

A: No. Metric threads follow ISO standards (measured in millimeters with standard 1.5mm pitches for common sizes), whereas PG threads follow a legacy German DIN standard based on internal conduit dimensions. Mixing them will cross-thread the component and compromise the environmental seal.

Q: Are these brass glands suitable for outdoor and marine exposure?

A: Yes. The electroplated nickel coating protects the underlying brass substrate against atmospheric oxidation, while the high-grade NBR/CR internal seals maintain elasticity, weather resistance, and IP68 integrity across wide outdoor temperature fluctuations.

Q: Do the cable glands come supplied with locknuts and O-rings?

A: Standard shipments include the complete assembly: gland body, clamping claw, sealing insert, locknut, and thread sealing O-ring. Individual components can also be supplied separately in bulk.

Q: What are the Minimum Order Quantities (MOQ) for standard versus custom configurations?

A: Standard catalog items have an MOQ of 100 pieces per size. Custom machining projects (such as non-standard threads or modified body dimensions) typically require an MOQ of 1,000 pieces per production run.

Q: What is the typical production and delivery lead time?

A: Standard stocked catalog items ship within 3 to 5 business days. Custom machining orders require 15 to 25 business days depending on order volume and plating schedules.
