What sizes are available for explosion proof glands?

Explosion proof glands are crucial components in hazardous environments where preventing the spread of explosions is of utmost importance. These glands are designed to seal cables and wires, providing a barrier that stops explosive gases, dust, or flames from passing through. As a reliable explosion proof gland supplier, we understand the diverse needs of our customers and offer a wide range of sizes to meet various applications.

Available Sizes for Explosion Proof Glands

Metric Sizes

Metric sizes are widely used in many industries, especially in Europe and Asia. Our explosion proof glands come in a comprehensive range of metric sizes, typically ranging from M12 to M63. The M12 gland is relatively small and is often used for applications where space is limited, such as in small control panels or instrumentation. It can accommodate cables with outer diameters typically between 4mm and 7mm.

Moving up, the M16 gland is a popular choice for general-purpose applications. It can handle cables with outer diameters in the range of 6mm to 10mm. This size is suitable for a variety of electrical and control systems, providing a good balance between cable capacity and gland size.

The M20 gland is another commonly used metric size. It can accommodate cables with outer diameters from 8mm to 13mm and is often used in industrial settings for power and control cables. For larger cables, we offer M25, M32, M40, M50, and M63 glands. The M63 gland, for example, can handle cables with outer diameters up to 42mm, making it suitable for high-power applications or large data cables.

NPT Sizes

National Pipe Thread (NPT) sizes are predominantly used in North America. Our explosion proof glands are available in NPT sizes starting from 1/8" to 2". The 1/8" NPT gland is relatively small and is used for applications with thin cables, such as in some communication or low-power electrical systems. It can typically accommodate cables with outer diameters of around 3mm to 6mm.

The 1/4" NPT gland is a more common size and can handle cables with outer diameters in the range of 5mm to 9mm. This size is suitable for a variety of industrial and commercial applications, including lighting and small control circuits.

The 3/8" NPT gland can accommodate cables with outer diameters from 7mm to 12mm, while the 1/2" NPT gland can handle cables up to 17mm in outer diameter. For larger cables, we offer 3/4", 1", 1 1/4", 1 1/2", and 2" NPT glands. The 2" NPT gland is capable of accommodating cables with outer diameters up to 38mm, making it suitable for high-power transmission and large-scale industrial applications.

G Sizes

G sizes, also known as BSP (British Standard Pipe) sizes, are commonly used in the UK and other countries that follow British standards. Our explosion proof glands are available in G sizes from 1/8" to 2". The 1/8" G gland is suitable for small cables with outer diameters around 3mm to 6mm.

The 1/4" G gland can handle cables with outer diameters in the range of 5mm to 9mm, similar to its NPT counterpart. The 3/8" G gland can accommodate cables with outer diameters from 7mm to 12mm, and the 1/2" G gland can handle cables up to 17mm in outer diameter. Larger G sizes, such as 3/4", 1", 1 1/4", 1 1/2", and 2", are available for cables with increasing outer diameters, up to 38mm for the 2" G gland.

Specific Product Examples

In addition to the standard sizes, we also offer specialized products such as the Brass Dome Plug NPT Thread, Brass Dome Plug Metric Thread, and Brass Dome Plug G Thread. These dome plugs are used to seal unused openings in explosion proof enclosures, providing an extra layer of protection against the ingress of explosive substances.

Choosing the Right Size

When selecting the appropriate size of explosion proof gland, several factors need to be considered. Firstly, the outer diameter of the cable is the most critical factor. The gland must be able to securely grip the cable without causing damage to the cable insulation. It is important to measure the cable diameter accurately and choose a gland size that is compatible.

Secondly, the type of environment in which the gland will be used is also important. In hazardous areas with high levels of dust or moisture, a gland with a higher ingress protection (IP) rating may be required. Additionally, the temperature range and chemical resistance of the gland material should be considered to ensure long-term reliability.

Finally, the installation requirements and available space should also be taken into account. In some cases, a smaller gland size may be preferred to save space, while in other cases, a larger gland may be necessary to accommodate multiple cables or larger cable bundles.
