Of course the use of the sealing washer will depend on several factors such as its ingress protection rating, the entry holes as well as the code of protection of the equipment. The cone and ring are absolutely imperative as they bring about a high level of reliability as they tighten the metal-to-metal surface.Įssentially a sealing washer at the equipment-gland entry interface provides protection. Armor Clamping Ring & Armor Clamping Cone.Here are the specific uses of some of the components of double compression cable glands.Įssentially this is used to close elements such as a tube, pipe, wire, cable or conductor. Double Compression Cable Glandsĭouble compression glands, in addition to these also comprise of cone and cone ring, which are absent in single compression glands. The big advantage of this rubber seal is that it resists oxidation, ozone as also many petroleum derivatives. It ensures that a nut once installed does not become loose and stays in place.Įssentially while helping avoid vibration, it also lowers noise levels significantly. Let us look at the specific functions of some of these parts in some detail:īesides offering a flawless bearing surface, importantly, it also distributes fastener load. Single compression glands comprise of gland body, gland body nut, neoprene rubber seal, rubber washer, check nut and flat washer. Let us also look at the parts that make up single and double compression glands. Components of Single Compression and Double Compression Glands Double compression glands are therefore used to support heavy armoured cables. With the double sealing offered, it protects the cable against moisture thus rendering it largely weather proof. On the other hand, in a double compression gland, the compression offered is both at the cable armour and the inner sheath. Single compression glands are typically used for light armoured cables. As such, it does not fully protect the entry of moisture and corrosive vapour. Let us look at the difference between the two in some detail: Difference between Single Compression Cable Glands and Double Compression Cable GlandsĪ single compression gland, essentially offers grip or compression at one place, namely the cable armour. The most commonly used glands include Brass Single Compression Cable Glands and Brass Double Compression cable glands.
