Description
Dowells Brass Cable Gland 19mm (3/4”) – Single/Double Compression
The Dowells Brass Cable Gland 19mm (3/4”) is designed to provide a dependable cable-entry solution for electrical panels, enclosures, junction boxes, control equipment, machinery and other suitable electrical installations. Available in Single Compression and Double Compression configurations, this gland size gives customers flexibility when selecting a cable-entry arrangement according to cable construction, enclosure requirements and installation conditions.
The 19mm designation corresponds to the nominal 3/4-inch size. However, customers should not select a cable gland simply from the cable conductor size or nominal gland designation. The actual outside diameter (OD) of the finished cable, cable construction, sheath dimensions, armour characteristics where applicable, enclosure entry and thread specification should all be checked before purchase.
For example, available 19mm (3/4″) brass cable-gland listings show that cable-gland selection can vary with cable construction and that the same nominal gland size should not be treated as a universal fit.

Dowells 19mm (3/4”) Single Compression Cable Gland
The Single Compression version is intended for applications where cable retention and sealing are achieved through a single compression arrangement around the cable sheath. It can be considered for compatible cable-entry applications where the cable construction and project specification call for a Single Compression gland.
The correct fit depends on the cable’s actual dimensions and the manufacturer’s specified gland range. Therefore, measure the cable OD before ordering rather than selecting the gland solely from a nominal cable size.

Dowells 19mm (3/4”) Double Compression Cable Gland
The Double Compression version provides an additional compression arrangement and is commonly associated with suitable armoured-cable applications where additional mechanical retention and sealing are required.
Double Compression glands generally incorporate components designed to secure the cable construction and, where applicable, clamp the armour. The precise construction, cable range, thread and performance characteristics should be verified against the applicable Dowells product documentation.
For customers working with armoured cables, our guide Armoured vs Unarmoured Cable Glands: Which One Do You Actually Need? can help explain the selection difference.
Important: Single Compression and Double Compression should not be considered interchangeable simply because both are identified as 19mm (3/4″). The cable construction and installation requirements determine the appropriate type. Technical references likewise emphasize checking cable OD and construction rather than relying only on nominal gland size.

How to Select the Correct 19mm (3/4”) Cable Gland
Before ordering the Dowells 19mm (3/4”) gland, check the following:
1. Measure the Actual Cable OD
The most important measurement is generally the finished cable’s outside diameter at the point where the gland will grip it. Cable conductor size in sq. mm does not by itself determine gland compatibility.
2. Identify the Cable Construction
Determine whether the cable is armoured or unarmoured. If it is armoured, additional dimensions such as bedding diameter and armour construction may be necessary for correct gland selection.
3. Select Single or Double Compression
Choose the compression type based on the cable design and project requirements. Single Compression offers a simpler compression arrangement, while Double Compression provides an additional compression/retention arrangement and is commonly used with compatible armoured cables.
4. Check the Enclosure Thread
The gland’s nominal 19mm size should not be assumed to identify the required enclosure thread. Confirm the thread type and dimensions required by the panel, junction box or electrical equipment.
5. Consider the Environment
For outdoor, wet, dusty, high-vibration or otherwise demanding installations, verify the required environmental protection and the manufacturer’s specified performance. Do not assume an IP rating solely because the gland is made from brass.
6. Follow Correct Installation Procedure
The cable should be prepared and the gland components assembled according to the manufacturer’s instructions. Incorrect stripping, poor sealing or excessive tightening can compromise the intended performance.

Frequently Asked Questions
1. What does 19mm (3/4”) mean on a Dowells Brass Cable Gland?
19mm (3/4”) is the nominal gland-size designation. It should not be interpreted as meaning that every cable with a 19mm outside diameter will fit. The actual cable OD must be compared with the specified cable range of the exact gland.
2. What cable size is suitable for a 19mm (3/4”) cable gland?
There is no universal conductor-size answer. The correct selection depends on the cable’s actual outside diameter, construction and the manufacturer’s gland dimensions. Some published 19mm gland charts associate the size with particular multi-core cable constructions, but these dimensions are approximate and can vary by cable manufacturer.
3. Is 19mm cable gland suitable for a 4 sq. mm cable?
It may be suitable for some cable constructions, but 4 sq. mm alone is not enough information to confirm compatibility. Published product charts, for example, associate a 19mm (3/4″) gland with certain 4.0 sq. mm four-core cable configurations, while also warning that cable dimensions can vary according to thickness and manufacturer. Always check the actual cable OD.
4. What is the difference between a 19mm Single Compression and Double Compression Cable Gland?
A Single Compression gland uses a single compression arrangement around the cable sheath. A Double Compression gland incorporates an additional compression arrangement and is commonly selected for compatible armoured-cable installations where additional mechanical retention and sealing are required.
5. Should I use Single Compression or Double Compression for an armoured cable?
For an armoured cable, the appropriate gland depends on the cable construction and installation requirements. A suitable Double Compression gland is commonly used where the design requires armour termination together with additional sealing and mechanical retention. Verify the exact gland type against the cable and project specification before installation.
6. Does a 19mm cable gland mean the cable diameter must be 19mm?
No. The 19mm designation is a nominal gland size and should not be treated as the gland’s universal cable-acceptance diameter. The manufacturer’s specified cable range and the actual cable OD determine compatibility.
7. Can a brass cable gland be used outdoors?
A brass gland can be suitable for outdoor applications when the specific gland design, sealing arrangement, thread, cable and environmental requirements are compatible. Outdoor suitability should not be assumed solely from the fact that the gland is brass. Verify the applicable environmental/IP specification.
8. What thread should I use with a 19mm (3/4”) cable gland?
The required thread depends on the enclosure or equipment entry. Confirm the required thread standard and dimensions before ordering. Do not assume that 19mm (3/4”) automatically identifies the enclosure thread.
9. How do I install a 19mm cable gland correctly?
First confirm the gland and cable dimensions, prepare the cable according to the manufacturer’s instructions, correctly position the gland components and tighten them according to the specified procedure. For armoured cable, armour preparation and termination are particularly important. Incorrect installation can affect sealing and mechanical retention.
10. Can I use the same 19mm gland for different cable brands?
Not automatically. Different cable manufacturers can produce cables with different insulation, bedding and sheath thicknesses, resulting in different overall diameters. The actual cable OD should be checked against the gland’s specified cable range each time.
11. Is Double Compression always better than Single Compression?
No. Double Compression is not automatically the better choice for every installation. The appropriate gland depends on the cable construction, environmental conditions, mechanical requirements, enclosure and project specification. Single Compression can be appropriate where its design meets the application requirements.
12. Can I replace a Single Compression gland with a Double Compression gland?
Do not treat them as direct substitutes simply because they have the same nominal size. Before changing the gland type, verify cable compatibility, gland dimensions, thread, enclosure clearance, installation requirements and the project’s technical specification.
