Description
HMI Brass Cable Gland 16mm (5/8”) – Single & Double Compression
The HMI Brass Cable Gland 16mm (5/8”) – Single & Double Compression is a nickel-plated brass cable-entry solution available in two configurations: SC016 Single Compression and DC016 Double Compression.
According to HMI’s current manufacturer information, SC016 and DC016 are both designated as 16mm (5/8″) cable-gland sizes. HMI specifies nickel-plated brass construction and a BSC (British Standard Conduit) entry thread for both ranges.
The two versions have different applications. HMI lists its Single Compression range for armoured and unarmoured cables, where the gland grips the outer cable sheath. Its Double Compression range is intended for armoured cables, sealing/gripping the inner and outer sheath while the cone and ring clamp the armour.
For engineers, contractors and purchase teams, the important point is that 16mm is the HMI gland-size designation and should not automatically be treated as the cable’s outside diameter. Cable OD, cable construction, armour, thread and installation requirements should be verified before ordering.

HMI 16mm Single Compression Cable Gland – SC016
The HMI SC016 is the Single Compression version of the 16mm (5/8″) cable gland. HMI lists this range for indoor or outdoor applications with armoured or unarmoured cables.
Its stated function is to grip the outer sheath of the cable. The product range is manufactured from nickel-plated brass and uses a BSC entry thread. HMI also lists Earth Tag and Shroud as accessories available on request.

How to Select the Correct HMI 16mm Cable Gland
1. Measure the Cable Outside Diameter
One of the most important selection factors is the actual outside diameter (OD) of the complete cable.
Do not assume that a 16mm cable gland is automatically intended for a 16mm cable OD. Cable-gland selection discussions commonly focus on cable diameter and the actual gland opening/sealing requirements. Reddit discussions also show that users frequently encounter confusion between gland designation, hole size and cable diameter.
Use the cable manufacturer’s datasheet or accurately measure the cable where appropriate.

What Size Cable Gland Do I Need for My Project?
- Check Whether the Cable Is Armoured
This is particularly important when deciding between SC016 and DC016.
- SC016: HMI lists the Single Compression range for armoured and unarmoured cables.
- DC016: HMI lists the Double Compression range for armoured cables and specifies armour clamping by the cone and ring.
3. Verify the Thread
HMI specifies a BSC (British Standard Conduit) entry thread for its Single Compression and Double Compression ranges. Make sure the equipment or enclosure entry is compatible before procurement.
4. Consider the Installation Environment
Check whether the installation is indoors or outdoors and whether the project has specific requirements concerning dust, moisture, sealing, corrosion, UV exposure or other environmental conditions.
Read:
What Is IP Rating on Cable Glands and Why Does It Matter?
Do not assume an IP rating for the HMI SC016/DC016 unless it is specifically confirmed by the applicable manufacturer documentation.
5. Check the Project Specification
For industrial projects, compare:
- Cable OD
- Armoured/unarmoured construction
- Cable type
- Gland configuration
- Thread
- Enclosure entry
- Environmental conditions
- Required accessories
- Manufacturer/project specifications
This approach is more reliable than choosing a gland solely by its nominal size.
Applications of HMI Brass Cable Gland 16mm
The HMI 16mm cable gland can be considered for suitable electrical panels, control panels, industrial enclosures, machinery, automation equipment, electrical equipment and cable-entry installations, subject to the cable and project requirements.
The SC016 is listed for armoured and unarmoured cables, making it relevant where outer-sheath gripping is required. The DC016 is listed for armoured cables and provides inner/outer sheath sealing and armour clamping.

Frequently Asked Questions – HMI Brass Cable Gland 16mm
1. What is the HMI Brass Cable Gland 16mm?
The HMI 16mm cable gland is available in two configurations: SC016 Single Compression and DC016 Double Compression. HMI lists both as 16mm (5/8″) sizes manufactured from nickel-plated brass with BSC entry thread.
2. What is HMI SC016?
SC016 is HMI’s 16mm (5/8″) Single Compression Cable Gland. HMI lists the Single Compression range for indoor or outdoor use with armoured or unarmoured cables and states that it grips the outer sheath.
3. What is HMI DC016?
DC016 is HMI’s 16mm (5/8″) Double Compression Cable Gland. HMI specifies the Double Compression range for armoured cables and describes its function as sealing/gripping the inner and outer sheath while the cone and ring clamp the armour.
4. What is the difference between SC016 and DC016?
The main difference is the compression and armour-termination arrangement.
SC016: Single Compression, suitable for armoured/unarmoured cables according to HMI’s range specification.
DC016: Double Compression, intended for armoured cables, with inner/outer sheath sealing and armour clamping.
5. Is a 16mm cable gland suitable for a 16mm cable?
Not necessarily. The HMI designation 16mm (5/8″) should not be interpreted as confirmation that a cable with exactly 16mm outside diameter will fit.
Cable-gland selection should be checked against the manufacturer’s applicable cable-size information and the actual cable OD. This distinction is also a recurring issue in online cable-gland discussions.
6. Can HMI SC016 be used for an unarmoured cable?
HMI lists its Single Compression range as suitable for armoured / unarmoured cables, so SC016 is the corresponding 16mm Single Compression option. The actual cable OD and installation requirements must still be verified.
7. Can HMI DC016 be used for an armoured cable?
HMI lists its Double Compression range for armoured cables and specifies that the cone and ring clamp the armour. Therefore, DC016 is the relevant HMI 16mm Double Compression configuration when its other selection requirements are met.
8. What material is the HMI 16mm Cable Gland?
HMI specifies nickel-plated brass as the material of construction for its Single Compression and Double Compression cable-gland ranges.
9. What thread does the HMI 16mm Cable Gland have?
HMI specifies BSC (British Standard Conduit) as the entry thread for both the Single Compression and Double Compression ranges.
10. What accessories are available for HMI SC016?
HMI lists Earth Tag and Shroud as accessories available on request for its Single Compression range.
11. What accessories are available for HMI DC016?
For the Double Compression range, HMI lists Earth Tag, Shroud, Stop Plug and Reducer/Adaptor as available on request.
12. How do I know whether I need Single or Double Compression?
Start by identifying the cable construction and termination requirement. If the cable is armoured and the installation requires armour clamping, the HMI Double Compression configuration is the relevant option. For armoured or unarmoured cable applications where outer-sheath gripping is required, HMI lists the Single Compression configuration.
