Description

Dowells Brass Cable Gland 70mm (2-3/4”) – Single/Double Compression

The Dowells Brass Cable Gland 70mm (2-3/4”) is designed for industrial cable-entry applications where the gland must provide secure mechanical retention and appropriate sealing at the equipment or enclosure entry. The product is available in Single Compression and Double Compression configurations, allowing selection according to cable construction and installation requirements.

For this size, choosing a gland purely because the cable is described as “70mm” is not recommended. Dowells’ selection data shows that gland selection is based on the actual overall cable diameter, and the applicable Double Compression model can change depending on that measurement.

For a broader selection method, see the Cable Gland Supplier India: 15 Expert Tips Guide.

Dowells 70mm Single Compression Cable Gland

The Dowells DGP10016 Single Compression Cable Gland is listed for a suitable cable diameter of 68.1–74.0 mm in Dowells’ published Cable Gland Selection Chart. This makes the selection particularly relevant when the measured overall cable diameter falls within that range.

Single Compression is generally considered when the installation requires the gland to grip and seal the cable at the outer sheath. However, the final selection should always consider the actual cable construction, gland specification, enclosure entry and project requirements.

Single Compression Specifications

Specification	Dowells Single Compression 70mm
Brand	Dowells
Product Type	Brass Cable Gland
Nominal Size	70mm
Approx. Imperial Size	2-3/4″
Configuration	Single Compression
Dowells Product Code	DGP10016
Suitable Cable Diameter	68.1–74.0 mm
Material	Brass
Selection Basis	Actual cable overall diameter
Application	Industrial cable-entry installations
Accessories	Select according to installation requirement

The 68.1–74.0 mm cable-diameter range is taken from Dowells’ published selection chart.

Dowells 70mm Double Compression Cable Gland

Double Compression cable glands require more careful selection because the correct model depends on the cable construction, armour arrangement and actual overall diameter.

Dowells’ published catalogue lists:

• DC-2.3/4″ — suitable overall diameter 63.6–69.5 mm
• DC-3″ — suitable overall diameter 69.6–74.5 mm

Therefore, if the actual cable OD is around 70 mm, the published range indicates that the DC-3″ model may be the applicable Dowells selection rather than automatically using DC-2.3/4″. The final selection should be checked against the current Dowells product specification and the actual cable construction.

Double Compression Specifications

Specification	Dowells Double Compression
Brand	Dowells
Product Type	Brass Cable Gland
Configuration	Double Compression
Nominal Size	Select according to cable OD/model
Imperial Reference	2-3/4″ / 3″ depending on selection
Material	Brass
Cable Type	Primarily selected according to cable construction
DC-2.3/4″ Cable OD	63.6–69.5 mm
DC-3″ Cable OD	69.6–74.5 mm
Selection Basis	Cable OD + construction + armour
Application	Industrial cable-entry installations

Dowells’ published catalogue is the appropriate reference for choosing between these ranges.

Single Compression vs Double Compression

Feature	Single Compression	Double Compression
Product family	Dowells DGP	Dowells DC/Double Compression range
Main selection factor	Cable overall diameter	Cable OD + construction + armour
Cable entry	Grip/seal at cable entry	Additional compression arrangement for applicable cable construction
Typical consideration	Suitable cable-entry applications	Armoured cable installations where double compression is required
70mm selection	DGP10016, 68.1–74.0 mm	Check actual OD; DC-2.3/4″ and DC-3″ cover different ranges
Best selection method	Measure actual cable OD	Measure OD and verify cable/armour specification
Installation	Select according to enclosure and cable	Select according to enclosure, cable and armour requirements

Important: Do not select the Double Compression gland merely from the nominal “70mm” label. The published Dowells ranges demonstrate why actual cable diameter matters.

How to Choose the Correct Dowells 70mm Cable Gland

Before ordering, check these points:

1. Measure the actual cable OD

Measure the finished overall diameter of the cable with a suitable measuring tool or confirm it from the cable manufacturer’s datasheet.

A gland’s nominal size should not be treated as the actual cable diameter. Cable-gland discussions also repeatedly highlight confusion between nominal gland/thread sizes and the actual cable dimension.

2. Check whether the cable is armoured

For armoured cable, the gland must be appropriate for the cable’s armour construction and installation requirements.

3. Decide between Single and Double Compression

The choice should be based on the cable construction, mechanical requirements and project specification—not simply on gland size.

4. Check the enclosure entry

Verify the required thread and enclosure entry before ordering. A correctly sized gland can still be unsuitable if its entry/thread arrangement does not match the equipment.

5. Consider the installation environment

For outdoor, dusty, wet, chemically exposed or otherwise demanding installations, select the gland and accessories according to the required environmental protection.

6. Confirm the manufacturer’s selection data

For large cable sizes such as 70mm, always verify the current Dowells selection chart before placing a bulk order.

Applications

Dowells Brass Cable Glands can be considered for industrial cable-entry applications where a suitable brass gland is required for connecting cables to electrical equipment, panels, junction boxes and enclosures.

The 70mm size is particularly relevant to larger industrial cables, but the correct gland should always be selected from the actual cable diameter and construction rather than the nominal cable description.

Typical application areas may include:

• Industrial electrical panels
• Power distribution equipment
• Control and electrical enclosures
• Switchgear installations
• Industrial machinery
• Power and infrastructure projects
• Cable termination areas
• Large electrical equipment
• Plant electrical installations

For armoured installations, the appropriate Double Compression model should be selected according to the cable’s actual dimensions and armour configuration.

Frequently Asked Questions

1. Is Dowells 70mm Cable Gland suitable for a 70mm cable?

Not automatically. The actual cable overall diameter should be checked against the Dowells selection range. For example, Dowells lists DGP10016 Single Compression for 68.1–74.0 mm cable diameter.

2. What is the Dowells code for 70mm Single Compression?

Dowells’ selection chart lists DGP10016 for Single Compression, with a suitable cable diameter of 68.1–74.0 mm.

3. Which Dowells Double Compression gland should I use for a 70mm cable?

Check the actual cable OD first. Dowells’ published catalogue lists DC-2.3/4″ for 63.6–69.5 mm and DC-3″ for 69.6–74.5 mm. Therefore, a measured 70mm OD falls into the latter published range, subject to confirming cable construction and the current manufacturer’s specification.

4. Should I select a cable gland by cable size or cable diameter?

Select it using the actual overall cable diameter, along with cable construction, armour, thread and application requirements. Nominal gland/thread sizes do not necessarily represent the actual cable diameter.

5. What is the difference between Single Compression and Double Compression cable glands?

The two configurations use different compression arrangements and are selected according to the cable construction and installation requirements. Double Compression glands are commonly considered for armoured cable applications where the armour needs to be accommodated and clamped appropriately.

6. Can I use the same 70mm gland for armoured and unarmoured cable?

No. Do not assume that the same gland configuration is suitable for both. Cable construction, armour and actual OD must be checked before selecting the gland.

7. How do I know if a Cable Gland will fit my enclosure?

Check the required thread/entry specification, available enclosure opening, cable OD and gland dimensions. A gland can have an appropriate cable range but still require a different entry arrangement.

8. Can I order Dowells Cable Glands in bulk?

Yes. For project or industrial quantities, you can contact Thunderbolt Electromech with the cable OD, cable type, armoured/unarmoured requirement, gland configuration and quantity so the appropriate product can be identified.
