Description

Dowells Brass Cable Gland 82mm (3-1/4”) – Single/Double Compression

The Dowells Brass Cable Gland 82mm (3-1/4”) – Single/Double Compression is designed for large cable-entry requirements in industrial electrical installations. It provides a product option for applications where a large-diameter cable requires an appropriately selected gland for connection to electrical equipment, panels or enclosures.

For this size, actual cable outside diameter is more important than the nominal 82mm designation. Dowells’ published selection chart lists DGP10018 for Single Compression with a suitable cable diameter of 80.6–87.0mm.

The Dowells catalogue separately identifies 82mm as 3-1/4″, confirming the nominal size relationship.

Dowells 82mm Single Compression Cable Gland

The Dowells 82mm (3-1/4″) Single Compression Cable Gland belongs to the large-size Single Compression range.

Dowells’ published catalogue identifies:

• 82mm
• 3-1/4″
• DGP10018

The selection chart gives DGP10018 a suitable overall cable diameter of 80.6–87.0mm. Therefore, customers should measure the actual cable OD before ordering rather than selecting the gland solely because the cable is described as an “82mm cable.”

Dowells 82mm Double Compression Cable Gland

The Double Compression version should be selected more carefully because the applicable product can depend on:

• Actual cable OD
• Armoured or unarmoured construction
• Armour dimensions
• Compression arrangement
• Thread/entry requirement
• Equipment or enclosure specification

For that reason, this product page should not assign one Double Compression product code to every 82mm cable.

Current manufacturer/catalogue information shows that Double Compression ranges are organized according to cable dimensions and configuration. Other published gland-selection data also demonstrates that an 82mm nominal gland is associated with a specific cable-OD range rather than simply every cable labelled 82mm.

Double Compression Specifications

Specification	Dowells 82mm Double Compression
Brand	Dowells
Product Type	Brass Cable Gland
Nominal Reference	82mm / 3-1/4″ class
Configuration	Double Compression
Material	Brass
Cable Type	Confirm armoured/unarmoured

Important: For an exact Double Compression order, provide the cable’s actual OD and whether it is armoured or unarmoured so the correct Dowells model can be confirmed.

Dowells’ chart specifically confirms the 80.6–87.0mm range for DGP10018.

How to Choose the Correct Dowells 82mm Cable Gland

1. Measure the actual cable OD

The first step is to determine the overall outside diameter of the finished cable.

Do not select the gland only from:

• Conductor size
• Cable voltage
• Nominal gland size
• Approximate cable description

For DGP10018, Dowells specifies 80.6–87.0mm. If your cable falls outside that range, another gland size may be required.

Read our detailed Cable Gland Size & Buying Guide for a practical selection process.

2. Confirm the cable construction

Before selecting Double Compression, establish whether the cable is:

• Armoured
• Unarmoured
• Single-core
• Multicore
• Power cable
• Control cable
• Special/flexible construction

The correct gland configuration can depend on the cable construction.

3. Select Single or Double Compression

Do not choose Double Compression simply because the cable is large.

The compression configuration should match the cable and project requirements.

For armoured installations, also check the armour dimensions and the applicable manufacturer selection table.

4. Verify the enclosure thread

The cable diameter and gland thread are two different specifications.

Before ordering, verify:

• Gland mounting thread
• Enclosure entry
• Panel opening
• Available installation space
• Thread standard

This is particularly important with large 82mm cable glands.

5. Consider the environment

For outdoor or demanding industrial applications, consider the required sealing and environmental protection.

Our article What Is IP Rating on Cable Glands and Why Does It Matter? explains why cable size, gland selection, enclosure entry and environmental requirements should be considered together.

Frequently Asked Questions

1. What is the Dowells 82mm Cable Gland size in inches?

Dowells identifies 82mm as 3-1/4 inches (3-1/4″) in its catalogue.

2. What is the Dowells product code for 82mm Single Compression?

The Dowells product code is DGP10018. The selection chart specifies a suitable cable diameter of 80.6–87.0mm.

3. What cable diameter does DGP10018 accommodate?

Dowells’ published selection chart lists 80.6–87.0mm for DGP10018.

4. Does an 82mm Cable Gland mean my cable must measure exactly 82mm?

No. 82mm is a nominal gland size/reference. The actual cable OD should be compared with the manufacturer’s specified range. DGP10018, for example, covers 80.6–87.0mm.

5. Which Double Compression Cable Gland should I use for an 82mm cable?

First measure the cable’s actual OD and identify whether it is armoured or unarmoured. Then select the applicable Dowells Double Compression model from the relevant manufacturer table. It would be incorrect to assign one universal Double Compression code to every 82mm cable.

6. Is an 82mm Single Compression gland suitable for armoured cable?

Do not assume suitability from size alone. Confirm the cable construction and the manufacturer’s specification for the particular gland. For armoured cable, the armour dimensions and required compression configuration should also be considered.

7. What is the difference between an 82mm Single and Double Compression Cable Gland?

They use different compression arrangements and are selected according to the cable construction and installation requirements. Double Compression selection additionally requires attention to the cable/armour configuration.

8. How do I select the correct Cable Gland for a large cable?

Measure the actual cable OD, identify the cable construction, determine Single or Double Compression requirements, verify the thread/entry and then compare the measurements with the manufacturer’s selection chart.

9. Can I select a Cable Gland based on conductor size?

No. Conductor cross-section alone is insufficient. Cable-gland selection should consider the overall cable diameter, cable construction, armour and gland configuration.

10. What information should I provide when ordering a Dowells 82mm Cable Gland?

Provide:

• Actual cable OD
• Cable type/construction
• Armoured or unarmoured
• Single or Double Compression
• Required thread/entry
• Quantity
• Project/application requirements

This information is much more useful than specifying only “82mm Cable Gland.”
