The brass cable gland is one of the key components in industrial and domestic electrical systems, used for introducing wires and cables into electrical panels, electrical equipment, and industrial devices. This component is made from brass alloy (a combination of copper and zinc) and, in addition to firmly holding the cable at the entry point, prevents the ingress of dust, moisture, and insects into the equipment. These glands, like armored cable glands, play a very important role in the safety of power distribution systems and increasing their service life.

A brass cable gland is a strategic accessory component in industrial wiring systems, responsible for creating a rigid, sealed, and safe connection between the cable and the body of equipment such as electrical panels, electric motors, and electrical junction boxes. This component is made from brass alloy with nickel plating to prevent oxidation. Using a compression mechanism and internal washers, it prevents environmental contaminants such as moisture, dust, and oil from entering the enclosure, while simultaneously securing the cables at the connection point so that tensile and compressive stresses do not cause damage to them.
If, according to the needs of your power distribution project, you need to purchase a brass cable gland, you must definitely refer to a reputable center whose product quality you are confident about. In addition to this matter, considering the following points is very important when purchasing a brass cable gland:
Before purchasing a brass gland, you must definitely specify its application. Whether you intend to use this product for industrial or domestic purposes is important. For example, in situations where continuous vibrations affect the gland and there is a possibility of explosion, explosion-proof brass cable glands must be used.
Given that the material and coating of the brass gland can differ, it is very important to examine the space in which the gland is to be placed before purchasing. If this type of gland is used in enclosed environments, you must use glands that have acceptable resistance to moisture and chemicals. However, if you need to use the gland in open spaces, you must definitely pay sufficient attention to the coating on these products.
It may be necessary to use a high number of glands in the power distribution system. This matter raises the final cost of the electrical wiring. For this reason, you must determine your budget and, accordingly, use the best glands with nickel, aluminum, copper, plastic, and stainless steel coatings. Each of these products has a different price and specific features. Therefore, it may not be necessary to purchase the most expensive model of brass cable gland.
A brass cable gland is a device for which you do not need to go through complicated steps to implement. In fact, the implementation stages of a brass cable gland are very simple in terms of installation and connection, and you can do it with a little engineering skill. Initially, it is necessary to place these glands into the cable opening. Then insert the threaded base of the gland into the junction box and then screw a final nut onto the threaded base.
This type of gland is only usable for various cables and is different from the glands used with various conduits. When using the gland, be careful not to damage the cable, because this can cause significant harm to your power distribution system.
The price of a brass cable gland depends on the size of these products. In general, the price of brass is higher compared to the plastic used in various glands, which, given the high quality of these products, is also very cost-effective. However, note that as the size of these glands increases, their price also goes up.
If you need to inquire about the daily price of brass cable glands, you can contact our experts at Rafi Industrial Group. Considering the daily price of brass and other metals used, the exact price of these cables can be announced to customers.
The threads present on the inner part of the explosion-proof cable gland are all designed according to a series of international standards named Panzergewinde, DIN 40430, under license from Germany. Although the brass cable gland is structurally manufactured from brass metal, to increase its resistance to chemical processes and oxidation, a protective coating known as nickel and chrome plating is usually applied to this component so that they can practically demonstrate maximum physical resistance in environments with high humidity.
One of the internal washers of the brass cable gland is usually made of stainless steel. These washers generally have high precision, and any application of force or pressure on them can cause damage and breakage. Therefore, these washers are made from stainless steel alloys to prevent damage to them. Another secondary washer, known as the cable protection washer, exists inside the gland, which is usually made of neoprene, possessing a self-extinguishing and flame-retardant property.
The flexible cable gland has the capability to momentarily withstand temperatures of up to 120 degrees Celsius above zero. However, in a working environment where the temperature may range from -40 degrees Celsius to 100 degrees Celsius above zero, these brass glands can completely maintain their structure and continue optimal performance in environments with temperature fluctuations. The coding method for the brass cable gland follows a specific and completely engineered set of rules.
Such that the code M PG 29 represents the features of a cable gland. The letter M indicates the metallic material of the gland. The letters PG indicate the thread standard of the component, and after that, the number 29 represents the size of the gland. This number is variable and can include other numbers as well, which we will explain in detail in the next section regarding gland size.
To introduce the size of the brass cable gland, it is necessary to introduce relatively complex and numerous elements. Gland sizing varies from M PG 07 to M PG 63. The 07 type of these glands, due to their lower gauge number and smaller dimensions, can naturally support and hold smaller-sized cables. However, their larger type, which has the gauge number 63, is capable of connecting larger-diameter cables with complete safety to other equipment and electrical panels.
If we want to list the standard size of brass cable glands in order, they include sizes 07, 09, 11, 13.5, 16, 21, 29, 36, 42, 48, and 63. Each of these mentioned figures has the capability to support a specific cable size. For example, the brass cable gland with specifications M PG 16 has the ability to support and hold cables in the size range of 10 to 14 millimeters. Other types of glands also support a specific range of cable sizes in exactly the same way. You must carefully check these dimensions by referring to the product catalog so that you can select and purchase the correct and suitable type for your project.
One of the very widely used metals today in various fields, especially cable connecting parts, is brass material. Brass glands, in order to have the highest level of resistance against natural destructive factors such as moisture, usually have a galvanized coating or nickel plating. This coating increases the intensity of the brass cable gland’s resistance to corrosion. Of course, the density of the brass metal in manufacturing glands is adjusted in such a way that they have acceptable resistance to pressure, tensile, and mechanical forces.
Metal glands are made from various materials, one example of which is brass. If we want to provide a general classification in terms of strength and resistance, stainless steel glands or steel types have higher resistance compared to the brass type. Whether you choose the brass or steel type depends on the usage situation of the gland.
Dear customers can purchase numerous and complete sizes of various types of metal glands and other products such as flexible conduit clamps from Rafi Industrial Group. All these parts are designed and manufactured according to defined international standards and will have very high durability and quality in high-stress environments.
