Description
HMI Brass Cable Gland 38mm (1-1/2”) – Single & Double Compression
The HMI Cable Gland 38mm (1-1/2″) is an industrial brass cable-entry solution available in Single Compression SC038 and Double Compression DC038 configurations. HMI specifies these cable glands with nickel-plated brass construction and BSC (British Standard Conduit) entry thread. The correct version should be selected according to cable construction, actual cable outer diameter (OD), armour arrangement and installation requirements.
For engineers, contractors, panel builders and purchase teams, the important point is that 38mm is the gland size designation and should not automatically be treated as the cable’s outside diameter. Cable gland selection should be based on the actual cable OD and manufacturer’s applicable dimensional/sealing requirements.
Thunderbolt’s cable-gland sizing guide explains why selecting a gland solely according to cable conductor size in sq.mm can lead to incorrect selection. Different cable manufacturers and constructions can produce different outside diameters even for cables with the same conductor cross-section.

HMI 38mm Single Compression Cable Gland – SC038
The HMI SC038 is the Single Compression version of the 38mm HMI cable gland range.
According to HMI, its Single Compression Cable Glands are suitable for indoor or outdoor applications with armoured or unarmoured cables. The primary function is to grip the outer sheath of the cable. HMI specifies nickel-plated brass as the material and BSC as the entry thread.

Which HMI 38mm Cable Gland Should You Choose?
The choice between SC038 and DC038 should not be made simply because both are 38mm.
Choose HMI SC038 when:
- The project specifies Single Compression.
- The cable is armoured or unarmoured.
- The cable construction is compatible with the HMI Single Compression gland.
- The cable OD falls within the applicable manufacturer range.
- The required entry thread matches BSC.
Choose HMI DC038 when:
- The installation requires Double Compression.
- The cable is armoured.
- Armour clamping is required.
- Inner and outer sheath sealing is part of the required gland arrangement.
- The cable OD and armour dimensions match the applicable specification.
HMI’s published distinction between the two types supports this selection approach.

Don’t Select a 38mm Cable Gland Only by Cable Sq.mm
A common procurement mistake is asking for a gland based only on the cable’s conductor size.
For example, the same nominal conductor size can have different finished cable diameters depending on:
- Insulation thickness
- Number of cores
- Armour
- Bedding
- Outer sheath
- Cable manufacturer
- Cable construction
The actual cable OD should therefore be checked against the applicable gland’s sealing requirements before ordering. Thunderbolt’s cable gland sizing guide specifically recommends using the cable’s actual outside diameter rather than relying only on sq.mm.
Cable Gland Selection: Other Factors to Check
Before purchasing an HMI 38mm cable gland, confirm:
- Cable outer diameter
- Armoured or unarmoured construction
- Single or Double Compression
- Gland size
- Required thread
- Enclosure entry
- Installation environment
- Required ingress protection
- Armour dimensions, where applicable
- Manufacturer/project specification
This is particularly important for outdoor and industrial installations where sealing and environmental protection can affect the reliability of the electrical enclosure.

Applications of HMI Brass Cable Gland 38mm
The HMI 38mm Single and Double Compression cable glands can be considered for suitable industrial cable-entry applications such as:
- Electrical panels
- MCC and distribution equipment
- Control panels
- Switchgear assemblies
- Junction boxes
- Industrial machinery
- Electrical enclosures
- Transformers and associated equipment
- Industrial automation systems
- Power and infrastructure projects
For DC038 Double Compression, the cable should be armoured and compatible with the applicable HMI specifications. For SC038, HMI lists both armoured and unarmoured cable applications.

FAQ – HMI Brass Cable Gland 38mm
I based the FAQ selection on recurring buyer/search intent around cable gland size, cable OD, Single vs Double Compression, armoured cable selection, thread compatibility and installation. Your own Thunderbolt cable-gland articles repeatedly identify cable OD and compression type as key customer-selection issues.
1. What is an HMI Cable Gland 38mm?
The HMI Cable Gland 38mm (1-1/2″) is an HMI cable-entry gland available as SC038 Single Compression and DC038 Double Compression. HMI specifies nickel-plated brass construction and BSC entry thread for these ranges.
2. What is the HMI SC038 cable gland?
SC038 is the HMI 38mm (1-1/2″) Single Compression Cable Gland. HMI specifies its Single Compression range for indoor or outdoor use with armoured or unarmoured cables, with the gland gripping the outer sheath.
3. What is the HMI DC038 cable gland?
DC038 is the HMI 38mm (1-1/2″) Double Compression Cable Gland. HMI specifies Double Compression glands for armoured cables, with sealing/gripping of the inner and outer sheath and armour clamping through the cone and ring.
4. What is the difference between SC038 and DC038?
SC038 is Single Compression, while DC038 is Double Compression. SC038 grips the outer sheath and is listed for armoured/unarmoured cables. DC038 is listed for armoured cables and additionally clamps the armour while sealing/gripping the inner and outer sheath.
5. Is HMI 38mm cable gland suitable for armoured cable?
Yes. HMI lists SC038 for armoured/unarmoured cables and DC038 for armoured cable applications. The correct selection should still be verified against the cable’s construction, OD and installation requirements.
6. Can HMI SC038 be used for unarmoured cable?
HMI specifies its Single Compression range, including SC038, for armoured/unarmoured cables.
7. Can I use HMI DC038 for an unarmoured cable?
HMI’s published Double Compression range is specified for armoured cables. Therefore, DC038 should not be selected for an unarmoured cable simply because the nominal gland size appears suitable.
8. Does a 38mm cable gland fit a 38mm diameter cable?
Not automatically. 38mm is the gland-size designation, not a universal statement that the gland accepts a 38mm cable OD. Always check the applicable HMI dimensional/sealing information against the actual cable diameter.
9. Should I choose HMI 38mm based on cable size in sq.mm?
No. Cable conductor size is not enough. The actual cable OD, construction, armour and gland configuration must be considered. Thunderbolt’s sizing guide specifically recommends selecting the gland according to actual cable OD.
10. What material is the HMI 38mm cable gland?
HMI specifies nickel-plated brass for its Single and Double Compression cable-gland ranges.
11. What thread does HMI 38mm cable gland use?
HMI specifies BSC (British Standard Conduit) as the entry thread for its Single Compression and Double Compression cable-gland ranges.
12. Is HMI 38mm cable gland suitable for outdoor use?
HMI lists its Single Compression and Double Compression ranges for indoor or outdoor applications. However, the complete installation must still be evaluated for cable construction, sealing requirements, thread, enclosure and required ingress protection.
13. Which is better: Single Compression or Double Compression?
Neither is universally “better.” The correct type depends on the cable and installation. HMI lists Single Compression for armoured/unarmoured cables and Double Compression for armoured cables. Double Compression provides the additional armour-clamping and inner/outer sheath sealing arrangement described by HMI.
14. What information should I give when ordering HMI 38mm cable glands?
For accurate procurement, provide:
- HMI SC038 or DC038
- Cable type
- Cable outer diameter
- Armoured/unarmoured
- Number of cores
- Armour details where applicable
- Required thread
- Quantity
- Application
This reduces the risk of receiving a nominally correct 38mm gland that is unsuitable for the actual cable.
