Description
Dowells Brass Cable Gland 16mm (5/8″) – Single/Double Compression
The Dowells Brass Cable Gland 16mm (5/8″) is designed for compatible electrical and industrial cable-entry applications. It is available in Single Compression and Double Compression configurations, allowing the gland to be selected according to the cable construction and installation requirement.
An important point for buyers is that 16mm (5/8″) is the nominal gland designation and should not automatically be treated as the cable’s outside diameter.
Dowells’ published selection information identifies DGP10003 as the 16mm (5/8″) Single Compression gland and specifies a 14.1–15.5 mm suitable cable diameter.
For the Double Compression armoured range, the current 2026 Dowells price list identifies DGP10038 / DC-5/8″ for 15.6–17.0 mm overall cable diameter, with a 3/4″ nipple.

Dowells 16mm (5/8″) Single Compression Cable Gland
The Dowells 16mm Single Compression Cable Gland is identified as DGP10003.
Dowells’ selection chart specifies the product for 14.1–15.5 mm cable diameter. The published product information also identifies the Single Compression range as a brass gland with a bright nickel-plated finish.
Single Compression Specifications
| Specification | Details |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Compression | Single Compression |
| Nominal Size | 16mm (5/8″) |
| Dowells Product Code | DGP10003 |
| Suitable Cable Diameter | 14.1–15.5 mm |
| Material | Brass |
| Finish | Bright Nickel Plated |
| Cable Type | Unarmoured applications, subject to applicable selection |
| Selection Basis | Actual cable OD + construction + thread + application |
The 14.1–15.5 mm range is the manufacturer’s published selection range for DGP10003.
Important sizing point
A customer searching for a 16mm cable gland may assume that the cable itself must have a 16mm OD. That is not correct for DGP10003. The published suitable cable diameter is 14.1–15.5 mm.
Therefore, before ordering, measure the complete cable OD or check the cable manufacturer’s datasheet.

Dowells 16mm (5/8″) Double Compression Cable Gland
For a Dowells 16mm (5/8″) Double Compression Cable Gland, the relevant medium-duty armoured configuration in the current 2026 Dowells price list is:
DC-5/8″ → DGP10038
The published selection range is 15.6–17.0 mm overall cable diameter, with a 3/4″ nipple.
This is different from the Single Compression DGP10003 and should therefore have a separate specification on the product page.
Double Compression Specifications
| Specification | Details |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Compression | Double Compression |
| Nominal Size | 16mm (5/8″) |

| Nipple | 3/4″ |
| Cable Type | Armoured cable |
| Material | Brass |

Key difference
The two products should not be selected simply because the customer asks for a “16mm gland.”
- DGP10003 → Single Compression → 14.1–15.5 mm
- DGP10038 → Double Compression → 15.6–17.0 mm, armoured cable, 3/4″ nipple
The actual cable construction and OD determine the appropriate configuration.
How to Choose the Correct Dowells 16mm Cable Gland
1. Check the actual cable OD
This is the most important selection step.
For the Single Compression DGP10003:
Suitable cable diameter: 14.1–15.5 mm
For the Double Compression DGP10038:
Suitable overall cable diameter: 15.6–17.0 mm
Do not select the gland merely because the cable is described as “16mm.”
2. Identify the cable construction
Determine whether the cable is:
- Armoured
- Unarmoured
- Single-core
- Multicore
- Power cable
- Control cable
- Other industrial cable construction
For armoured-cable requirements, read our Armoured vs Unarmoured Cable Glands guide.
3. Select Single or Double Compression
The compression configuration should match the cable and project specification.
Do not substitute the Single Compression DGP10003 for a Double Compression requirement simply because both are described as 16mm/5/8″.
4. Check the entry/thread
The gland must be compatible with the actual panel, enclosure, junction box, switchgear or equipment entry.
For the DGP10038 Double Compression configuration, Dowells’ 2026 price list specifies a 3/4″ nipple.
5. Check environmental requirements
For outdoor, wet, dusty, chemical or other demanding installations, check the required sealing and ingress-protection requirements against the applicable product documentation.

Common Problems When Buying a 16mm Cable Gland
| Customer Problem | Common Reason | Better Approach |
| Customer assumes 16mm gland accepts 16mm cable | Nominal size confused with cable OD | Check manufacturer’s range |
| Gland is too loose | Cable OD is below the applicable range | Measure actual cable OD |
| Gland doesn’t fit | Cable OD is outside range | Select correct gland size |
| Wrong compression type | Single/Double requirement ignored | Confirm cable construction |
| Wrong gland for armoured cable | Armour not considered | Check cable construction |
| Gland doesn’t fit equipment | Entry/thread not verified | Confirm panel/enclosure entry |
| Customer selects from conductor sq.mm | Cable OD ignored | Use complete cable OD |
The published Dowells data clearly demonstrates why nominal size should not be used as the only selection criterion.

FAQs – Dowells Brass Cable Gland 16mm
1. What is a Dowells 16mm (5/8″) Cable Gland?
It is a Dowells brass cable-entry gland in the 16mm (5/8″) nominal size. The Single Compression version is DGP10003, while the Double Compression armoured version is DC-5/8″ / DGP10038.
2. What cable diameter fits the Dowells 16mm Single Compression gland?
The Dowells selection chart specifies DGP10003 for 14.1–15.5 mm cable diameter.
3. Does 16mm mean the cable must have exactly 16mm OD?
No. The 16mm (5/8″) designation is the nominal gland size. DGP10003 is specified for 14.1–15.5 mm cable diameter.
4. What is the Dowells product code for the 16mm Single Compression gland?
The product code is DGP10003. Dowells identifies it as the 16mm (5/8″) Single Compression gland.
5. What is the Dowells 16mm Double Compression product code?
For the medium-duty armoured Double Compression range, the current 2026 Dowells price list identifies DC-5/8″ / DGP10038. Its listed overall cable diameter range is 15.6–17.0 mm.
6. What cable diameter fits the Dowells 16mm Double Compression gland?
The DGP10038 / DC-5/8″ configuration is listed for 15.6–17.0 mm overall cable diameter.
7. What is the difference between the 16mm Single and Double Compression glands?
The Single Compression DGP10003 is specified for 14.1–15.5 mm cable diameter, while the Double Compression DGP10038 is listed for 15.6–17.0 mm overall cable diameter and is in Dowells’ medium-duty armoured brass gland range.
8. Is the Dowells 16mm Double Compression gland suitable for armoured cable?
Yes. DGP10038/DC-5/8″ appears in Dowells’ Double Compression Type Medium Duty Armoured Brass Cable Glands section.
9. What nipple size is listed for the Dowells DGP10038?
The current Dowells price list specifies a 3/4″ nipple for DGP10038/DC-5/8″.
10. Can I select a 16mm cable gland according to cable sq.mm?
It is better not to. Cable-gland selection should consider the finished cable’s outside diameter and construction, rather than conductor cross-sectional area alone.
11. Why doesn’t my 16mm cable fit the 16mm cable gland?
Because “16mm” does not necessarily mean a 16mm cable OD. For example, DGP10003 is specified for 14.1–15.5 mm, whereas DGP10038 is specified for 15.6–17.0 mm overall diameter.
12. Can the same 16mm gland be used for different cables?
Only when the cable falls within the applicable manufacturer’s dimensional range and satisfies the required construction, compression and installation conditions.
13. How do I know whether I need Single or Double Compression?
Start with the cable construction and project specification. For an armoured-cable requirement calling for the Double Compression configuration, select the applicable Dowells Double Compression gland rather than the Single Compression DGP10003.
14. Where can I buy Dowells Brass Cable Gland 16mm in India?
You can contact Thunderbolt Electromech India Pvt. Ltd. for Dowells 16mm (5/8″) cable-gland requirements, including Single Compression and the appropriate Double Compression configuration.
