Description
Dowells Brass Cable Gland 25mm (1″) – Single/Double Compression
The Dowells Brass Cable Gland 25mm (1″) is an industrial cable-entry solution available in Single Compression and Double Compression configurations. It is designed for compatible electrical installations where secure cable entry, mechanical retention and appropriate cable termination are required.
The 25mm (1″) designation should not be treated as the cable’s actual outside diameter. Cable-gland selection should be made using the actual finished cable OD together with the cable construction, armour, gland configuration and required thread.
This is particularly important for the Double Compression version. Dowells’ published catalogue identifies a DC-1″ medium-duty armoured brass cable gland and gives a suitable overall diameter range of 19.6–22.5 mm for that particular configuration.
For a broader explanation of how to select a gland correctly, see our Cable Gland Supplier India – Complete Industrial Buying Guide.
Dowells 25mm Single Compression Brass Cable Gland
The Dowells 25mm (1″) Single Compression Cable Gland is intended for compatible cable-entry applications where a single-compression configuration is specified.
For procurement, do not select the gland solely from the cable conductor size. Check the cable’s finished OD and the applicable Dowells product selection data.

Important Sizing Note
The 25mm / 1″ designation does not mean that every 25mm outside-diameter cable will fit this gland. Always check the manufacturer’s applicable cable range before ordering.
Our article What Size Cable Gland Do I Need for My Project? explains why actual cable OD is one of the most important measurements when choosing a Cable Gland.
Dowells 25mm Double Compression Brass Cable Gland
The Dowells 25mm (1″) Double Compression Cable Gland is intended for applications requiring a double-compression gland arrangement. Dowells’ published price list identifies DC-1″ as a medium-duty armoured brass cable gland and specifies 19.6–22.5 mm suitable overall diameter for that catalogue entry.
Dowells’ selection chart also demonstrates the manufacturer’s approach of selecting double-compression glands according to the actual cable diameter, rather than simply matching the nominal gland designation to cable OD.

*The 19.6–22.5 mm range applies to the specific DC-1″ catalogue entry cited above; confirm the current manufacturer’s catalogue/model before using it as a universal specification for every Dowells 25mm configuration.

Single Compression vs Double Compression
Single Compression
Single Compression is suitable when the cable and project specification call for a single-compression gland arrangement. The selection should be based on the manufacturer’s applicable cable range, cable OD, construction and thread.
Double Compression
Double Compression is used where the installation requires the corresponding double-compression arrangement. Dowells’ published DC-1″ entry is specifically listed under medium-duty armoured brass cable glands.
Quick Comparison
| Feature | Single Compression | Double Compression |
| Brand | Dowells | Dowells |
| Nominal size | 25mm (1″) | 25mm (1″) |
| Construction | Brass | Brass |
| Compression | Single | Double |
| Cable OD | Verify manufacturer range | Verify manufacturer range |
| Armour | Check application | Important for armoured application |
| Thread | Verify | Verify |
| Selection basis | Cable OD + construction + thread | Cable OD + armour + construction + thread |
| Best approach | Match project specification | Match project specification |
Do not select between Single and Double Compression simply because both are labelled 25mm (1″). The cable construction and installation requirement should determine the configuration.
How to Choose the Correct Dowells 25mm Cable Gland
Before placing your order, check the following:
1. Measure the actual cable OD
Use the cable datasheet or measure the finished cable diameter accurately.
2. Identify the cable construction
Confirm whether it is:
- Armoured
- Unarmoured
- Single-core
- Multicore
- Power cable
- Control cable
- Other project-specific cable
3. Select Single or Double Compression
The appropriate configuration depends on the cable and project specification.
4. Check the thread
Confirm the required thread on the gland and the entry point of the equipment, panel or enclosure.
5. Check the manufacturer’s cable range
This is especially important for the Double Compression version because Dowells publishes cable-diameter selection ranges for its gland configurations.
6. Check the environment
Consider indoor/outdoor installation and any project requirements concerning sealing, environmental exposure or enclosure compatibility.

Frequently Asked Questions
1. What is a Dowells Brass Cable Gland 25mm (1″)?
It is a Dowells brass Cable Gland in the 25mm / 1″ nominal size category, available in Single and Double Compression configurations for compatible cable-entry applications.
2. Does 25mm mean the cable must have a 25mm outside diameter?
No. The 25mm designation should not automatically be treated as the cable OD.
For example, Dowells’ published DC-1″ catalogue entry specifies a suitable overall cable diameter of 19.6–22.5 mm.
This is why the actual cable OD should always be checked before ordering.
3. What cable size fits a Dowells 25mm Double Compression Cable Gland?
For the specific DC-1″ entry in the published Dowells price list, the suitable overall diameter is 19.6–22.5 mm.
However, verify the current Dowells catalogue and exact product code before treating this range as the specification for a particular stock item.
4. What is the difference between 25mm Single and Double Compression Cable Glands?
They use different compression arrangements. The correct choice depends on the cable construction and installation requirements.
Double Compression is particularly relevant to applicable armoured-cable installations, while Single Compression should be selected where the project calls for that configuration.
5. Can I use a 25mm Cable Gland for an armoured cable?
Do not assume suitability based only on the 25mm designation. Check the cable construction and select the applicable Dowells armoured gland configuration.
Dowells lists the DC-1″ under its medium-duty armoured brass Cable Glands.
6. Is 1 inch the same as 25mm for a Cable Gland?
The product is commonly designated 25mm / 1″ in the requested product naming. However, the nominal designation should not be confused with the cable’s usable diameter or the gland’s complete dimensional specification.
7. How do I select a Dowells 25mm Cable Gland?
Check:
- Cable outside diameter
- Cable construction
- Armour
- Single/Double Compression requirement
- Thread
- Installation environment
- Manufacturer’s selection data
Dowells’ own selection chart uses suitable cable diameter as a key selection parameter.
8. Does cable conductor size in sq.mm determine the gland size?
No. Conductor cross-section and finished cable OD are different measurements.
The outer diameter depends on the complete cable construction, including insulation, sheath and, where applicable, armour.
9. What thread should I use with a Dowells 25mm Cable Gland?
The thread should be confirmed from the specific gland configuration and equipment/enclosure entry. Do not infer the complete thread specification simply from the 25mm product designation.
10. Can I use the same 25mm Cable Gland for different cable diameters?
Only when the actual cable OD falls within the applicable manufacturer’s cable-selection range for that specific gland.
Dowells’ selection chart provides different gland codes for different cable-diameter ranges.
11. Is a brass Cable Gland suitable for industrial applications?
Brass Cable Glands are commonly used for industrial electrical cable-entry applications. Actual suitability depends on the product specification, cable construction, equipment entry and environmental requirements.
12. Where can I buy Dowells Brass Cable Gland 25mm in India?
Thunderbolt Electromech India Pvt. Ltd. supplies industrial Cable Glands and related cable accessories, including Dowells products. You can use the Cable Gland category to browse the available range.
