Description
Dowells Brass Cable Gland 22mm (7/8″) – Single/Double Compression
The Dowells Brass Cable Gland 22mm (7/8″) is an industrial brass cable-entry solution available in Single Compression and Double Compression configurations. It is suitable for compatible electrical and industrial installations where the gland must be correctly matched with the cable construction and dimensions.
A key point for buyers is that 22mm is the nominal gland size and should not automatically be interpreted as the cable’s outside diameter. Dowells’ published selection chart lists DGP10005 for the 22mm / 7/8″ Single Compression gland, with a suitable cable diameter of 16.5–19.0 mm.

1. Dowells 22mm (7/8″) Single Compression Cable Gland
The Dowells 22mm Single Compression Cable Gland is identified as DGP10005 in Dowells’ product documentation. The manufacturer’s selection chart specifies 16.5–19.0 mm as the suitable cable-diameter range for this model.
This makes measuring the actual cable outside diameter essential before ordering. The conductor size alone does not establish whether the gland will fit because cable insulation and overall construction can change the finished cable diameter.
Single Compression Specifications
| Specification | Dowells 22mm Single Compression |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Nominal Gland Size | 22mm |
| Imperial Size | 7/8″ |
| Product Code | DGP10005 |
| Suitable Cable Diameter | 16.5–19.0 mm |
| Configuration | Single Compression |
| Material | Brass |
| Selection Basis | Actual cable OD + application requirements |
Dowells’ current 2026 price-list information also identifies DGP10005 as the 7/8″ / 22mm Single Compression product.
2. Dowells 22mm (7/8″) Double Compression Cable Gland
Double Compression selection needs additional care because the appropriate gland depends on the cable construction, cable diameter and application.
For armoured cable applications, Dowells provides dedicated Double Compression ranges. Its published medium-duty armoured range, for example, uses product codes based on the actual overall cable diameter rather than simply assigning one Double Compression model to every nominal 22mm gland requirement. The older Dowells selection table lists separate models such as DC-3/4″, DC-7/8″, DC-1″ and others according to overall diameter.
Dowells also lists a separate Double Compression Un-Armoured range, reinforcing the need to identify the cable type before selecting the exact model.
Double Compression Specifications
| Specification | Dowells 22mm Double Compression |
| Brand | Dowells |
| Product Type | Brass Cable Gland |
| Nominal Size | 22mm / 7/8″ |
| Configuration | Double Compression |
| Cable Type | Select according to armoured/unarmoured construction |
| Cable Selection | Actual overall cable diameter |
| Product Code | Depends on applicable Double Compression range |
| Thread | Confirm from selected model |
| Material | Brass |
| Selection Method | Manufacturer selection chart + cable measurements |
Important: I would not publish a single cable-OD range or Double Compression product code for every “22mm Double Compression” application. Dowells has multiple Double Compression configurations, so the exact model should be matched to the cable construction and OD.

Does 22mm Mean the Cable OD Is 22mm?
No.
This is one of the most important points to make clear on this product page.
For the Dowells DGP10005 22mm / 7/8″ Single Compression gland, the published suitable cable diameter is 16.5–19.0 mm, not 22mm.
Therefore, buyers should not select the gland simply by saying:
“My cable is 22mm, so I need a 22mm gland.”
Instead, check:
Cable construction → actual cable OD → gland configuration → thread → application.

How to Select the Correct Dowells Cable Gland
Before purchasing a Dowells Brass Cable Gland 22mm, check the following:
1. Measure the cable outside diameter
Use the cable manufacturer’s datasheet or measure the actual finished cable OD.
2. Check cable construction
Determine whether the cable is:
- Armoured
- Unarmoured
- Single-core
- Multicore
- Other specialised construction
3. Select Single or Double Compression
The correct configuration depends on the cable and installation requirements.
4. Confirm the thread
Do not assume the nominal 22mm gland designation alone confirms every thread requirement.
5. Check the manufacturer’s selection chart
For the 22mm Single Compression model, Dowells specifies DGP10005 and 16.5–19.0 mm cable diameter.
6. Check the project specification
For industrial projects, the project engineer, cable manufacturer or equipment manufacturer may specify a particular gland type or material.

Frequently Asked Questions
1. What is a Dowells Brass Cable Gland 22mm (7/8″)?
It is a Dowells brass cable gland identified by the nominal 22mm / 7/8″ size. The Dowells Single Compression version is DGP10005.
2. What cable diameter fits the Dowells 22mm Single Compression gland?
Dowells’ selection chart specifies 16.5–19.0 mm for DGP10005. Always check the latest manufacturer information before final selection.
3. Does a 22mm Cable Gland fit a 22mm cable?
Not necessarily. The nominal gland size and cable outside diameter are not interchangeable terms. For DGP10005, Dowells specifies a 16.5–19.0 mm cable-diameter range.
4. What is the difference between 22mm Single Compression and Double Compression?
The two configurations have different construction and selection requirements. Double Compression selection is particularly dependent on cable construction and whether the cable is armoured or unarmoured.
5. Can I choose the Cable Gland based on cable sq.mm?
Not reliably. Cable conductor size is useful information, but the finished cable’s outside diameter is a critical gland-selection dimension.
For example, cables with the same conductor cross-section can have different outside diameters depending on insulation, sheath, armour and cable construction.
6. Is the Dowells 22mm gland suitable for armoured cable?
The answer depends on the exact Dowells Double Compression model. For an armoured cable, select the appropriate armoured gland based on the actual cable construction and overall diameter rather than assuming that every 22mm gland is suitable.
7. How do I select a Dowells 22mm Double Compression gland?
First identify:
- Armoured or unarmoured cable
- Actual cable OD
- Required gland configuration
- Required thread
- Installation environment
- Project/manufacturer specification
Then select the appropriate Dowells model from the relevant selection table.
8. Why does the cable OD matter so much?
The gland needs to match the cable’s actual dimensions to provide the intended grip and sealing arrangement. Selecting only by nominal gland size can result in an incorrect fit.
9. What thread should I use with a 22mm Dowells Cable Gland?
Do not assume the thread solely from “22mm / 7/8″.” Confirm the thread of the specific gland model and installation/equipment entry before ordering.
10. Can the same 22mm Cable Gland be used for every cable?
No. Cable diameter, construction, armour, thread and gland configuration can change the appropriate selection. The Dowells selection chart itself provides different cable-diameter ranges across its gland sizes.
11. Where can I buy Dowells 22mm Cable Gland in India?
Thunderbolt Electromech India Pvt. Ltd. offers Dowells Cable Gland products and other industrial electrical accessories. For bulk/project requirements, provide the cable OD, cable construction, required configuration and quantity so the correct product can be checked.
