Description
Dowells Brass Cable Gland 12mm (1/2″) – Single/Double Compression
The Dowells Brass Cable Gland 12mm (1/2″) is designed for cable-entry applications where a correctly selected brass gland is required for mechanical retention and cable termination. The 12mm/1/2″ designation refers to the Dowells gland size; it should not be assumed to mean that every 12mm outside-diameter cable will fit.
For proper selection, consider the cable’s actual overall diameter, cable construction, armour, gland configuration and thread requirement before ordering. Dowells’ selection chart lists DGP10002 as the 12mm Single Compression gland, suitable for a 12.6–14.0 mm cable diameter.

1. Dowells 12mm (1/2″) Single Compression Cable Gland
The Dowells 12mm Single Compression Cable Gland is listed as DGP10002 in Dowells’ product documentation. The manufacturer selection chart specifies a suitable cable diameter of 12.6–14.0 mm for this model.
This makes actual cable measurement important before purchasing. A cable’s conductor cross-section, such as 2.5 sq.mm, 4 sq.mm or 6 sq.mm, does not by itself determine the correct gland. The complete cable construction and outside diameter need to be checked.
Single Compression Specifications
| Specification | Dowells 12mm Single Compression |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Gland Size | 12mm |
| Inch Size | 1/2″ |
| Product Code | DGP10002 |
| Suitable Cable Diameter | 12.6–14.0 mm |
| Configuration | Single Compression |
| Material | Brass |
| Selection Basis | Actual cable OD + application requirements |
The 2026 Dowells price list also identifies DGP10002 as the 12mm / 1/2″ Single Compression gland.
Important: Always verify the latest manufacturer’s selection data against your actual cable before ordering.
2. Dowells 12mm (1/2″) Double Compression Cable Gland
Double Compression glands require more careful selection because the appropriate model depends on the cable construction and application, rather than simply the nominal 12mm designation.
For armoured and unarmoured cables, Dowells provides different gland ranges and selection tables. Therefore, it would be misleading to assign one universal cable-OD range or product code to every “12mm Double Compression” application.
For an armoured cable installation, check the appropriate Dowells Double Compression model against the cable’s overall diameter, armour construction and required thread. For unarmoured applications, Dowells also has a separate Double Compression unarmoured range.
Double Compression Specifications
| Specification | Dowells 12mm Double Compression |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Nominal Size | 12mm / 1/2″ |
| Configuration | Double Compression |
| Application | Select according to cable construction |
| Cable Selection | Actual overall cable diameter |
| Cable Type | Armoured/unarmoured selection dependent |
| Thread | Confirm against required gland configuration |
| Material | Brass |
| Selection Method | Manufacturer chart + actual cable measurements |
Do not select a Double Compression gland merely because the cable is described as “12mm”. Confirm the exact Dowells model from the current selection chart.
Single Compression vs Double Compression
Single Compression Comparison
| Feature | Dowells 12mm Single Compression |
| Product Code | DGP10002 |
| Nominal Size | 12mm / 1/2″ |
| Cable Diameter | 12.6–14.0 mm |
| Cable Selection | Based on actual cable OD |
| Main Selection Factor | Cable OD and application |
| Best Approach | Match cable construction and OD with manufacturer data |
Double Compression Comparison
| Feature | Dowells 12mm Double Compression |
| Nominal Size | 12mm / 1/2″ |
| Configuration | Double Compression |
| Cable Selection | Based on actual cable OD |
| Armoured Cable | Select appropriate Dowells armoured model |
| Unarmoured Cable | Select appropriate Dowells unarmoured model |
| Product Code | Depends on applicable Double Compression range |
| Thread | Confirm from selected model |
| Best Approach | Match cable construction + OD + thread |
Dowells’ published tables show that its Double Compression ranges are separated according to cable/application type, so the exact model should be confirmed before purchase.
How to Choose the Correct Dowells Cable Gland
Before ordering a Dowells Brass Cable Gland 12mm, check these points:
- Measure the actual cable outside diameter.
- Check whether the cable is armoured or unarmoured.
- Decide whether Single Compression or Double Compression is required.
- Confirm the required thread type and size.
- Check the installation environment and sealing requirements.
- For project work, compare the selected gland with the cable manufacturer’s datasheet and project specification.
- Do not select a gland based only on conductor size or the nominal gland number.

Frequently Asked Questions
1. What is a Dowells 12mm (1/2″) Cable Gland?
It is a Dowells brass cable-entry gland identified as 12mm / 1/2″. The Single Compression version is listed as DGP10002. Its manufacturer selection range is 12.6–14.0 mm cable diameter.
2. Does a 12mm Cable Gland fit a 12mm diameter cable?
Not necessarily. For Dowells DGP10002 Single Compression, the published suitable cable diameter is 12.6–14.0 mm. Therefore, do not assume that “12mm” means a 12mm cable OD.
3. What cable size fits a Dowells 12mm Single Compression gland?
The Dowells selection chart lists 12.6–14.0 mm cable diameter for DGP10002. Always verify your actual cable OD against the latest manufacturer documentation.
4. What is the difference between Single Compression and Double Compression Cable Glands?
Single Compression and Double Compression glands use different construction and selection approaches. The correct choice depends on the cable construction, particularly whether the cable is armoured, along with cable OD and installation requirements.
5. Can I select a Cable Gland based only on cable sq.mm?
No. Cable conductor size alone is not enough. Two cables having the same conductor cross-section can have different overall diameters because of insulation, sheath, armour and construction. Measure or obtain the actual cable OD before selecting the gland.
6. Is a 12mm gland suitable for armoured cable?
That depends on the exact Dowells gland configuration. Armoured cable installations require the appropriate gland designed for the cable construction and armour arrangement. Do not assume that the 12mm Single Compression model is automatically the correct armoured-cable solution.
7. How do I select the correct Dowells Double Compression gland?
Check the cable type, actual overall diameter, armour construction where applicable, required gland size and thread. Then match those details against the applicable Dowells selection table.
8. Which is more important: cable size or cable diameter?
For gland selection, actual cable outside diameter is critical. The conductor’s sq.mm rating alone does not establish which gland will fit.
9. What should I check before buying a Dowells Cable Gland?
Check:
- Cable overall diameter
- Armoured/unarmoured construction
- Single/Double Compression requirement
- Thread requirement
- Installation environment
- Required sealing/protection level
- Manufacturer/project specifications
For a detailed checklist, see our Cable Gland Supplier India buying guide.
10. Where can I buy Dowells Brass Cable Glands in India?
Thunderbolt Electromech India Pvt. Ltd. supplies industrial electrical products including Cable Glands. For bulk or project requirements, share the cable OD, cable construction, required quantity and preferred gland configuration so the appropriate product can be checked.
