Brass Earth Tags for Cable Glands

Brass Earth Tags for Cable Glands

We are leading manufacturers, suppliers, and exporters of Brass Earth Tags for Cable Glands from our precision manufacturing facility in India. Our brass earth tags are precision-pressed components designed specifically to provide reliable earth continuity in electrical installations where cable glands are used. Also known as earthing tags, grounding tags, earth bonding tags, cable gland earth tags, brass earthing washers, and brass earth bonding washers, these components are widely used in the electrical, industrial, oil and gas, marine, petrochemical, and infrastructure sectors.

Brass earth tags are flat, pressed metal components with a hole in the centre to fit over cable glands, combined with a projecting tail or lug that accepts an earthing conductor. When fitted correctly beneath or above the cable gland locknut, they create a secure, low-impedance electrical path between the gland body and the earthing conductor, ensuring compliance with wiring regulations and earthing standards such as BS 7671 (IET Wiring Regulations), IEC 60079, and IS 732.

Types of Brass Earth Tags We Manufacture

Our range of brass earth tags covers a comprehensive set of sizes and configurations to suit all standard cable gland thread sizes and earthing conductor termination methods. We manufacture the following variants:

Standard Brass Earth Tags (Flat Type): Simple flat pressed tags with a central hole and a flat tail for conductor connection. Available for M12, M16, M20, M25, M32, M40, M50, M63, and M75 thread sizes. These correspond to all standard metric cable gland entry sizes.

Formed/Bent Brass Earth Tags: Tags where the conductor tail is bent upward at 90° or at other angles to allow easier conductor termination, particularly useful in enclosures with limited space.

Double Earth Tags: Tags with two tails for connecting two separate earthing conductors, commonly required in ring main or cross-bonding applications.

Wide Tail Earth Tags: Tags with a wider conductor tail offering a larger contact area, suitable for high-current earthing applications or where additional mechanical strength is needed.

Brass Earth Tags with Serrated Face: Tags with a serrated or toothed contact face to bite through paint or coating on enclosures, ensuring metallic earth continuity even on painted or powder-coated surfaces.

Tinned Brass Earth Tags: Electro-tinned earth tags offering improved corrosion resistance, particularly for marine, coastal, and outdoor electrical installations.

Nickel-Plated Brass Earth Tags: For high-performance corrosion resistance in aggressive chemical environments.

Material and Specifications

Our brass earth tags are pressed from high-quality brass sheet in alloys including CW614N (CZ121/BS 2874) free-cutting brass, CW508L (CZ108) cartridge brass, and CW612N (CZ131) leaded brass, all of which offer excellent electrical conductivity, corrosion resistance, and machinability. The electrical conductivity of brass is approximately 26–28% IACS, more than adequate for all earthing and bonding applications. Standard thickness ranges from 0.8 mm to 2.0 mm depending on the tag size and load-carrying requirement. Custom thicknesses are available on request.

Surface finishes available include natural brass (as pressed), electro-tinned, nickel-plated, and hot-dip tinned. All tags are manufactured in compliance with relevant British Standards, IEC standards, and Indian electrical wiring standards.

Standard Thread Sizes and Dimensions

We supply brass earth tags for the following standard cable gland entry thread sizes: M12×1.5, M16×1.5, M20×1.5, M25×1.5, M32×1.5, M40×1.5, M50×1.5, M63×1.5, M75×1.5, as well as PG-thread cable glands (PG7, PG9, PG11, PG13.5, PG16, PG21, PG29, PG36, PG42, PG48). NPT and BSP thread compatible earth tags are also available. Bulk orders or custom size requirements for non-standard gland thread diameters are accommodated through our in-house tooling design and press shop.

Manufacturing Process

Brass earth tags are manufactured using a multi-stage progressive die pressing process on our high-speed mechanical and hydraulic presses. The process begins with high-quality brass strip coil material, which is fed through a progressive die that blanks, pierces the central hole, forms the tail, and optionally bends or shapes the tag in a single automated sequence. This ensures consistent dimensional accuracy, tight tolerances, and high production throughput. All tags undergo 100% visual inspection and periodic dimensional checks using calibrated gauges. Surface plating is carried out in our in-house electroplating facility under controlled conditions.

Applications of Brass Earth Tags

Brass earth tags find application across a wide range of industries and installation types. In electrical panel manufacturing, earth tags are fitted on every cable gland to provide the mandatory earth continuity path between the armour or screen of the incoming cable and the metallic panel structure. In hazardous area installations classified as Zone 1, Zone 2, or Zone 21/22, approved earth tags are essential safety components to prevent static charge build-up and ensure explosive atmosphere compliance per ATEX and IECEx requirements.

In marine and offshore installations, tinned or nickel-plated earth tags are used on all cable gland penetrations through ship bulkheads and offshore platform junction boxes. In industrial automation and control systems, earth tags provide screen continuity for instrumentation cables, reducing electrical noise and EMI interference. In building infrastructure including hospitals, data centres, airports, and commercial complexes, earth tags are part of the standard installation on all armoured cable terminations.
