Description

Dowells Brass Cable Gland 35mm (1-3/8″) – Single/Double Compression

The Dowells Brass Cable Gland 35mm (1-3/8″) is an industrial brass cable-entry solution available in Single Compression and Double Compression configurations. It is designed for compatible electrical and industrial cable-entry applications where the gland needs to be matched correctly with the cable’s physical dimensions and construction.

One of the most important points when purchasing a Cable Gland is that the nominal gland size does not necessarily equal the cable’s outside diameter. Dowells lists DGP10009 as the 35mm / 1-3/8″ Single Compression gland, with a suitable cable diameter of 31.1–34.5 mm.

For a detailed explanation of cable OD, gland type, armour, thread and application selection, see our Cable Gland Supplier India: 15 Expert Tips to Choose the Right Cable Gland.

1. Dowells 35mm (1-3/8″) Single Compression Cable Gland

The Dowells 35mm Single Compression Cable Gland is identified by DGP10009. Dowells’ selection chart specifies a suitable cable diameter of 31.1–34.5 mm for this model.

This makes the actual cable OD an essential selection parameter. The conductor size in sq.mm should not be used as the sole basis for choosing a gland because insulation, sheath and overall cable construction can change the finished cable diameter.

Single Compression Specifications

Specification	Dowells 35mm Single Compression
Brand	Dowells
Product Type	Brass Cable Gland
Nominal Gland Size	35mm
Imperial Size	1-3/8″
Product Code	DGP10009
Suitable Cable Diameter	31.1–34.5 mm

Dowells’ 2026 price-list information also identifies DGP10009 as the 35mm / 1-3/8″ Single Compression gland.

2. Dowells 35mm (1-3/8″) Double Compression Cable Gland

The Dowells 35mm Double Compression Cable Gland should be selected according to the actual cable construction and outside diameter rather than simply using the nominal 35mm designation.

Dowells has different Double Compression ranges for different cable/application requirements. Its current documentation includes separate ranges for armoured and unarmoured cable applications, so the exact model and cable range should be confirmed against the relevant Dowells selection table.

This is particularly important when a customer asks for a “35mm Double Compression” gland without providing the cable OD or cable construction.

Double Compression Specifications

Specification	Dowells 35mm Double Compression
Brand	Dowells
Product Type	Brass Cable Gland
Nominal Size	35mm / 1-3/8″

Important: I recommend not publishing one universal cable-OD range for every Dowells 35mm Double Compression application. The correct model depends on the applicable Dowells range and cable construction.

Dowells’ published 2026 information separates its Double Compression selections according to application/cable construction, so the exact model should be confirmed before ordering.

Does 35mm Mean the Cable OD Is 35mm?

No.

This is an important point to explain to customers.

The Dowells DGP10009 35mm / 1-3/8″ Single Compression Cable Gland is specified for a 31.1–34.5 mm cable diameter.

Therefore:

35mm gland ≠ automatically 35mm cable OD.

The correct selection process is:

Actual cable OD → Cable construction → Single/Double Compression → Thread → Application requirements

How to Choose the Correct Dowells 35mm Cable Gland

Before ordering the Dowells Brass Cable Gland 35mm, check:

1. Actual Cable Outside Diameter

Measure the finished cable OD or obtain it from the cable manufacturer’s datasheet.

2. Cable Construction

Identify whether the cable is:

• Armoured
• Unarmoured
• Single-core
• Multicore
• Power cable
• Control cable

3. Compression Type

Determine whether the application requires Single Compression or Double Compression.

4. Thread Requirement

Confirm the thread required by the equipment or enclosure entry and match it with the selected gland.

5. Manufacturer Selection Data

For the Dowells DGP10009 Single Compression model, the published suitable cable diameter is 31.1–34.5 mm.

6. Installation Requirements

Consider the enclosure, installation environment and any project-specific requirements before final selection.

Frequently Asked Questions

1. What is a Dowells Brass Cable Gland 35mm (1-3/8″)?

It is a Dowells brass Cable Gland identified by the nominal 35mm / 1-3/8″ size. The Dowells Single Compression model is DGP10009.

2. What cable diameter fits the Dowells 35mm Single Compression gland?

Dowells specifies 31.1–34.5 mm as the suitable cable-diameter range for DGP10009.

3. Does a 35mm Cable Gland fit a 35mm cable?

Not necessarily. The 35mm designation is the nominal gland size. The Dowells DGP10009 Single Compression gland is specified for 31.1–34.5 mm cable diameter.

4. What is the difference between a 35mm Single Compression and Double Compression Cable Gland?

The configurations differ in their construction and selection requirements. Double Compression selection requires additional consideration of cable construction, particularly for armoured cable applications.

5. Can I select a 35mm Cable Gland based only on cable sq.mm?

No. Conductor cross-sectional area does not by itself establish the required gland. The actual finished cable OD should be checked because cable construction can change the overall diameter.

6. Is a Dowells 35mm Cable Gland suitable for armoured cable?

The appropriate answer depends on the specific gland configuration. For an armoured cable, select the applicable Dowells Double Compression model according to cable construction, armour arrangement and actual cable OD.

7. How do I select a Dowells 35mm Double Compression gland?

Check:

1. Cable OD
2. Armoured or unarmoured construction
3. Compression configuration
4. Required thread
5. Installation environment
6. Project/equipment specification

Then match those details with the applicable Dowells selection table.

8. Why is cable OD important when choosing a Cable Gland?

The gland must correspond to the physical dimensions of the cable for the intended gripping and sealing arrangement. A nominal gland number alone does not provide enough information.

9. What thread should I use for a Dowells 35mm Cable Gland?

Confirm the thread for the specific Dowells model and ensure it matches the equipment or enclosure entry. Do not infer the exact thread solely from the 35mm nominal size.

10. Can the same 35mm Cable Gland be used for every cable?

No. The correct gland can vary according to cable OD, construction, armour, compression type and thread. Dowells’ selection chart demonstrates that its nominal gland sizes correspond to defined cable-diameter ranges.

11. Why does the 35mm gland size not equal the cable size?

Cable-gland sizing uses product-specific dimensions and cable-entry requirements. The nominal size is not necessarily a direct measurement of the cable’s finished outside diameter. The Dowells 35mm Single Compression example demonstrates this clearly: 35mm nominal gland → 31.1–34.5 mm suitable cable diameter.

12. Where can I buy Dowells 35mm Cable Glands in India?

Thunderbolt Electromech India Pvt. Ltd. supplies industrial electrical products including Dowells Cable Glands. For bulk or project requirements, provide the cable OD, cable construction, required configuration and quantity so the appropriate product can be checked.
