What Makes a Brass Cable Gland the Right Choice for Your Application?

You're specifying cable entry components for a control cabinet, a lighting system, or a piece of industrial equipment. The connection needs to be secure, durable, and resistant to the environment—whether that's moisture, dust, vibration, or temperature extremes. A brass cable gland is designed for exactly that: a robust sealing device that anchors cables firmly while preventing ingress of contaminants. The BH Series from JIXIANG is one example—a brass hose connector built for reliable performance across construction, power equipment, and machinery manufacturing applications. This guide covers the key features—material construction, sealing performance, thread options, and temperature range—so you can evaluate whether a brass cable gland is the right fit for your cabling needs.

Material Matters – Why Brass Is the Preferred Choice

The material of a cable gland determines its durability, corrosion resistance, and suitability for different environments. Brass cable glands are finely processed and offer good conductivity, corrosion resistance, and high temperature resistance. The BH Series features nickel-plated brass construction for the body and cap nut, providing an extra layer of protection against corrosion and wear.

Nickel-Plated Brass for Enhanced Durability

The nickel plating on the brass body and cap nut adds significant protection against corrosion, making the gland suitable for both indoor and outdoor applications. This is especially important in environments where moisture, chemicals, or salt spray are present.

Material Composition – What's Inside the Gland

Beyond the brass body, the gland's internal components are equally important. The clamping insert is made from polyamide PA6 V2, providing secure cable retention without damaging the cable jacket. The sealing ring and O-ring are made from NBR (nitrile rubber) , offering excellent resistance to oils, fuels, and a wide range of chemicals.

Sealing Performance – IP Ratings That Matter

The effectiveness of a cable gland is measured by its ability to keep contaminants out. The BH Series brass cable glands are designed with robust sealing systems that provide reliable protection in demanding environments. With IP68-rated sealing using EPDM or NBR rubber seals, these glands deliver protection against dust ingress and continuous immersion in water.

Understanding IP68 Protection

An IP68 rating means the gland is dust-tight and can withstand continuous immersion in water beyond 1 meter. This level of protection is essential for outdoor installations, marine applications, and environments where equipment is exposed to washdowns or flooding.

Sealing Materials – NBR and EPDM

The choice of sealing material affects the gland's performance across different temperatures and chemical exposures. NBR (nitrile rubber) offers excellent resistance to oils and fuels, making it suitable for industrial and automotive applications. EPDM provides superior resistance to weathering, ozone, and steam, making it ideal for outdoor and high-temperature environments.

Thread Options – Compatibility Across Global Standards

Cable glands must fit the threaded entries on your equipment. The BH Series brass cable glands support a wide range of thread standards: Metric, PG, G, and NPT thread. This broad compatibility ensures you can find the right gland for your specific equipment, whether you're working with European, UK, or North American standards.

Metric Thread – The European Standard

Metric threads are the most common standard in European and Asian equipment. They are specified by diameter in millimeters (e.g., M20, M25) and are widely used in industrial control panels and automation equipment.

PG Thread – The German Standard

PG (Panzergewinde) threads are a German standard, commonly found in older European equipment and some industrial applications. They are specified by a PG number (e.g., PG13.5, PG21) and remain in use across many existing installations.

G Thread – The British Standard Pipe Thread

G threads (also known as BSPP) are the British standard pipe thread, commonly used in the UK and many other countries. They are parallel threads specified by nominal size (e.g., G1/2, G3/4) and are frequently found in plumbing and pneumatic applications.

NPT Thread – The North American Standard

NPT (National Pipe Thread) is the tapered thread standard used in North America. Tapered threads create a pressure-tight seal through thread interference, making them suitable for high-pressure applications. NPT threads are specified by nominal size (e.g., 1/2" NPT, 3/4" NPT).

Temperature Range – Performance Across Extremes

Cable glands must maintain their sealing integrity across a range of temperatures. The BH Series brass cable glands are rated for a working temperature range of -40°C to 110°C, with short-term exposure up to 120°C. This wide operating range makes the glands suitable for applications from cold outdoor environments to high-temperature industrial processes.

Low-Temperature Performance

The -40°C rating ensures reliable sealing and cable retention even in freezing conditions. This is critical for outdoor installations in cold climates, refrigeration equipment, and cold storage facilities.

High-Temperature Performance

The 110°C continuous rating and 120°C short-term rating make the glands suitable for high-temperature environments such as engine compartments, industrial ovens, and heat treatment equipment.

Applications Across Industries

Brass cable glands are used across a wide range of industries and applications where reliable cable entry is essential.

Lighting systems: Indoor and outdoor lighting installations require secure, weatherproof cable entry points.
Charging stations: New energy vehicle charging infrastructure demands high-voltage connectors with reliable sealing.
Petrochemical industry: Oil storage and transportation pipelines require connectors that maintain integrity under pressure.
Marine and vessel applications: Supply ships and offshore installations use sealed connectors for fire-fighting pipelines and liquid pipelines.
Construction and power equipment: General industrial and commercial applications where durable, reliable cable connections are required.
