Which Cable Gland Is Best for Your Application?

Cable glands are devices that are commonly used in wiring, telecommunication, automation, and electrical instrumentation to safely enclose cables. They can both seal and terminate devices to keep the connection between a cable and a device protected. Most cable glands manufacturers will have a cable gland catalogue. From there you will find a wide cable gland selection, so it can be helpful to know what the differences are between the two basic types. Here is what you need to know about single cord, and multi cord formats.

Single Cord Grips

Single cord grips hold just a single cable. When you tighten the gland, it compresses around the cord which helps to prevent it from being pulled out. They can also be found in a 90 degree, or liquid tight format. Depending on the material that the gland is made out of, it could resist temperatures from 30 degrees below Fahrenheit, to more than 225 degrees above Fahrenheit.

Multi Cord Grips

Where your application calls for multiple cables of different diameters to be protected, then you would look for a multi cord grip. These work by having removable layers of EPDM rubber inserts. Generally these glands can fit up to four cords.

Cable glands come in many different materials, including plastic, aluminum, stainless steel, regular steel, and brass to fit any application. Whatever your industry, if you have cables that are at risk of disconnecting from a device, or need protection from moisture or other elements, then either a single or multi cord gland could be the perfect solution.
