Description
HMI Brass Cable Gland 32mm (1-1/4”) – Single & Double Compression
The HMI Brass Cable Gland 32mm (1-1/4”) – Single & Double Compression is a nickel-plated brass cable-entry solution available in two HMI variants: SC032 Single Compression and DC032 Double Compression.
HMI’s current product information identifies SC032 and DC032 as 32mm (1-1/4”) gland sizes. HMI specifies nickel-plated brass construction and BSC (British Standard Conduit) entry thread for its Single and Double Compression ranges.
The two variants have different functions. HMI lists the Single Compression range for armoured and unarmoured cables, where the gland grips the outer sheath. The Double Compression range is specified for armoured cables, sealing/gripping the inner and outer sheath while the cone and ring clamp the armour.
For engineers, contractors, panel builders and purchase departments, the 32mm (1-1/4”) designation should not automatically be considered the cable’s outside diameter. The actual cable OD, cable construction, armour, thread and project requirements should be checked before selecting the gland.
For the complete selection process, see the Thunderbolt Cable Gland Supplier India: 15 Expert Tips to Choose the Right Cable Gland.
HMI 32mm Single Compression Cable Gland – SC032
The HMI SC032 is the Single Compression version of the 32mm (1-1/4”) cable gland.
HMI specifies its Single Compression range for indoor or outdoor cable-gland applications suitable for armoured or unarmoured cables. Its stated function is to grip the outer sheath of the cable.
The construction is nickel-plated brass, with a BSC entry thread. HMI lists Earth Tag and Shroud as accessories available on request.

Key selection point: The difference between SC032 and DC032 is not simply the product name. The cable construction and required termination arrangement determine which configuration should be considered. HMI specifically identifies Single Compression for armoured/unarmoured cables and Double Compression for armoured cables with armour clamping.
How to Select the Correct HMI 32mm Cable Gland
1. Check the Actual Cable OD
Do not assume that a 32mm cable gland is automatically suitable for a cable with a 32mm outside diameter.
The nominal gland designation and the cable’s actual outside diameter are different selection considerations. Cable OD should be checked against the manufacturer’s applicable selection information.
This is particularly important for industrial procurement because cables with similar conductor sizes can have different overall diameters depending on construction and insulation.
Read the dedicated Thunderbolt guide:
What Size Cable Gland Do I Need for My Project?
2. Identify Armoured or Unarmoured Cable
This determines whether the Single or Double Compression configuration should be considered.
- SC032: HMI lists Single Compression for armoured and unarmoured cables.
- DC032: HMI lists Double Compression for armoured cables, with the cone and ring clamping the armour.
3. Verify the Entry Thread
HMI specifies BSC – British Standard Conduit thread for its Single and Double Compression ranges. Confirm that the equipment, panel or enclosure entry is compatible before ordering.
4. Consider the Installation Environment
HMI lists both configurations for indoor or outdoor cable-gland applications, but the actual project may have additional requirements for environmental protection.
Before specifying an IP requirement, check the manufacturer’s applicable technical documentation rather than assuming a particular IP rating from the product category.
See:
What Is IP Rating on Cable Glands and Why Does It Matter?
- Check the Complete Cable Construction
Before placing a purchase order, confirm:
- Overall cable diameter
- Armoured or unarmoured construction
- Cable type
- Gland type
- Entry thread
- Installation location
- Enclosure requirements
- Required accessories
- Manufacturer/project specifications
This approach is more reliable than choosing the gland purely from the 32mm designation.
Applications of HMI Brass Cable Gland 32mm
The HMI Brass Cable Gland 32mm can be considered for suitable electrical panels, control panels, industrial enclosures, machinery, automation equipment, electrical installations and cable-entry applications, subject to cable and project requirements.
The SC032 is listed by HMI for armoured and unarmoured cables and is designed to grip the outer sheath. The DC032 is listed for armoured cables and provides inner/outer sheath sealing and armour clamping.
Industrial cable-gland requirements can also appear in project specifications and tenders according to actual cable OD, rather than simply nominal gland size. For example, recent Indian tender specifications classify cable-gland requirements by cable OD ranges such as up to 20mm, above 20–30mm, above 30–40mm and so on.

Frequently Asked Questions – HMI Brass Cable Gland 32mm
1. What is the HMI Brass Cable Gland 32mm?
The HMI 32mm cable gland is available as SC032 Single Compression and DC032 Double Compression. HMI identifies both as 32mm (1-1/4”) cable-gland sizes and specifies nickel-plated brass construction with BSC entry thread.
2. What is HMI SC032?
SC032 is the HMI Single Compression Cable Gland designated 32mm (1-1/4”). HMI lists its Single Compression range for armoured and unarmoured cables and states that it grips the outer sheath.
3. What is HMI DC032?
DC032 is HMI’s Double Compression Cable Gland designated 32mm (1-1/4”). HMI specifies the Double Compression range for armoured cables and describes the cone and ring as clamping the armour.
4. What is the difference between SC032 and DC032?
SC032 is Single Compression and is listed for armoured and unarmoured cables.
DC032 is Double Compression and is listed for armoured cables, with inner/outer sheath sealing and armour clamping.
Therefore, the correct choice depends on cable construction and termination requirements.
5. Is a 32mm cable gland suitable for a 32mm cable?
Not automatically. The 32mm (1-1/4”) designation identifies the HMI gland size; it should not be interpreted as confirmation that a cable with exactly 32mm OD will fit.
Always verify the applicable cable OD range against the manufacturer’s selection information.
6. Which HMI 32mm cable gland should I use for an armoured cable?
Both configurations may be relevant depending on the required termination. HMI lists SC032 for armoured and unarmoured cables, while DC032 is specifically listed for armoured cables and incorporates armour clamping.
For the distinction, read Armoured vs Unarmoured Cable Glands.
7. Can HMI SC032 be used for an unarmoured cable?
HMI lists its Single Compression range as suitable for armoured / unarmoured cables, so SC032 is the corresponding 32mm Single Compression configuration. The cable’s actual dimensions and other installation requirements still need to be checked.
8. Is HMI DC032 suitable for an armoured cable?
HMI lists the Double Compression range for armoured cables and specifies that the cone and ring clamp the armour. DC032 is therefore the corresponding HMI 32mm Double Compression configuration when the other selection requirements are satisfied.
9. What material is the HMI 32mm Cable Gland?
HMI specifies nickel-plated brass as the material of construction for its Single and Double Compression cable-gland ranges.
10. What thread does the HMI 32mm Cable Gland use?
HMI specifies BSC (British Standard Conduit) as the entry thread for both its Single Compression and Double Compression ranges.
11. What accessories are available for HMI SC032?
HMI lists Earth Tag and Shroud as accessories available on request for the Single Compression range.
12. What accessories are available for HMI DC032?
For the Double Compression range, HMI lists Earth Tag, Shroud, Stop Plug and Reducer/Adaptor as available on request.
13. How should I select a 32mm cable gland for an industrial project?
Start with the actual cable OD, then confirm armoured/unarmoured construction, compression type, thread, environmental requirements and project specifications.
