Introduction
What are the different parts of a cable gland?
It is a common question that will come up into your mind if you are searching for the best cable glands.
You see, cable glands are bulkhead modules which enable barrier penetration while offering sealing protection.
They are typically called as strain reliefs or sealing glands.
They can seal around one or various probes, cables, or wires.
Cable glands are often configurable to work along with any cable in a particular size range,
They serve various functions including:
- Extra sealing on the part of the cable entering the enclosure
- Environmental protection
They can facilitate earth continuity in the cases of armored cables, and offer a holding force on the cable.
That sufficient guarantee levels of cable pull out resistance.
Cable glands are utilized on all kinds of:
- data & telecommunications cable
- instrumentation
- control
- electric power

When choosing a cable gland, there are various steps to take into consideration.
That will guarantee the appropriate cable gland is utilized in the application.
The initial step is to determine the kind of cable to be utilized and check the size, material properties and construction of the cable.
But in this article, we will not talk about them.
Instead, we will present you the different parts of a cable gland and their corresponding functions.
Are you now ready?
Let’s get started!
Types of Cable Gland
But first, you need to understand that there are two different types of cable glands:
- single compression cable gland
- double compression cable gland
These two types of cable glands have a different set of parts.
But what are they?
What is Single Compression Cable Gland?
In case you are not aware of what is a single compression cable gland, read further.
A single compression cable gland is consumed for lightly armored cables.
They have scope for corrosive and moisture vapor to enter and impact the cable.
Single compression design does not feature cone and cone ring.
You see:
There is only Neoprene rubber seal which provides mechanical support toe gland once you attach the cable.
Single compression Stainless Steel Cable Gland Parts
It’s cable gland parts name include:
o gland body nut
o gland body
o flat washer
o lock nut
o rubber washer
o rubber seal
o neoprene
On the flip side, there is also double compression cable gland.
You see:
The double compression cable gland is utilized where largely armored wires are getting our or coming into the board.
Double compression cable glands provide additional support.
Double compression cable glands feature a double sealing feature.
Apart from that:
You will find compression at the inner sheath and cable armor.
Hence you need to ask yourself the question:
Do you prefer a flameproof or weatherproof cable glands?
After that, you need to consider a double compression design.
Double compression cable gland parts
Bear in mind also that a double compression design has a cone ring and cone.
That presents mechanical assistance to the cable.
Meanwhile, talking about the parts of a double compression cable gland.
It has the following cable gland parts name:
- check nut
- neoprene rubber seal
- cone ring
- cone
- gland body nut and;
- gland body
In this section, allow us to distinguish the complete parts of cable gland:
Sealing Nut
On the other hand, sealing nuts offer a dependable seal against liquids or gas, even under high pressure.
These are simple to install, doubly reliable.
It seals at the same time inside the thread and under the head.
The one-piece sealing nut is easy to fit and comes along with a captive seal to avoid loss.
cable gland sealing nut
You see, sealing nuts are 1-piece structural elements.
Sealing from leakage is always possible in the thread and the bearing face.
Additionally, sealing nuts offer a high-strength threaded connection without loss of preload force.
Claw
This cable gland parts name is created to stay on the gland body.
It works by saving installation expenses.

The housing and the body are composed of all other components of the cable gland.
Washer
A washer is a disk-shaped, thin plastic or metal piece of hardware.
It has a hole in the center.
washer
Its primary function is to help sprinkle a load of a threaded faster like the nut on the cable gland.
It is also utilized for:
- lowering vibration
- avoiding corrosion
- avoiding wear
- spacing
O Ring
The o ring is much the same to a seal.
It’s seated in a groove in one of the 2 parts to be combined then compressed among such 2 components to the corresponding groove.
You see, it builds a securely sealed joint.
They can be utilized in dynamic joints where there’s movement and in fixed or static applications.
O ring
In case you didn’t know yet, O rings come in different materials fitted to various purposes.
A few have a high-temperature tolerance for use in both cold and hot settings.
