Description

HMI Brass Cable Gland 82mm (3-1/4”) – Single & Double Compression

The HMI Brass Cable Gland 82mm (3-1/4”) is a nickel-plated brass cable-entry solution available in Single Compression SC082 and Double Compression DC082 configurations. The HMI range uses a BSC (British Standard Conduit) entry thread.

The two configurations should be selected according to the cable construction and installation requirements. The SC082 Single Compression Cable Gland is intended for suitable armoured or unarmoured cable applications and grips the outer sheath. The DC082 Double Compression Cable Gland is intended for armoured cable applications and provides compression around the cable while the cone and ring arrangement clamps the armour.

For engineers and procurement teams, the important point is that 82mm (3-1/4”) should not be used as a substitute for measuring the cable outside diameter. The cable OD, construction, armour, thread and application all need to be checked before final selection.

Important sizing note

Do not assume that an 82mm Cable Gland accepts an 82mm cable OD. Cable-gland manufacturers use nominal sizes and separate cable-clamping dimensions. Published selection charts show that the gland designation and cable OD are different specifications.

Before ordering, confirm the actual cable OD from the cable manufacturer’s datasheet or by accurate measurement and compare it with the applicable HMI dimensional information.

How to Choose the Correct HMI 82mm Cable Gland

1. Check the Cable Outside Diameter

Start with the complete cable OD, not just the conductor size.

The same conductor cross-sectional area can occur in cables with different constructions, insulation, number of cores and armour arrangements. Therefore, cable size in sq.mm should not be used as a direct substitute for cable OD.

Read our detailed What Size Cable Gland Do I Need for My Project? guide.

2. Determine Whether the Cable Is Armoured

The cable construction affects the gland configuration.

HMI specifies its Single Compression range for armoured and unarmoured cables, while the Double Compression range is specified for armoured cables.

Armoured vs Unarmoured Cable Glands: Which One Do You Actually Need?

3. Check the Thread Requirement

HMI specifies BSC as the entry thread for these cable-gland ranges. Confirm that the equipment or enclosure entry is compatible before placing an order.

Do not confuse the gland’s nominal size with its mounting thread.

 

4. Consider the Installation Environment

For outdoor or demanding industrial installations, consider moisture, dust, chemicals, UV exposure, mechanical stress and the required sealing/protection level.

Applications

The HMI Brass Cable Gland 82mm can be considered for compatible industrial cable-entry applications where the SC082 or DC082 configuration, cable dimensions, thread and installation requirements match.

Potential applications include:

• Industrial electrical panels
• Power distribution equipment
• Electrical enclosures
• Control cabinets
• Junction boxes
• Industrial machinery
• Manufacturing facilities
• Armoured cable installations
• Electrical infrastructure projects
• OEM equipment
• Industrial control systems
• Cable-entry applications

The final product selection should be verified against the actual cable construction, cable OD, manufacturer specifications and project requirements.

Frequently Asked Questions

1. What is an HMI 82mm Cable Gland?

The HMI 82mm Cable Gland is available in SC082 Single Compression and DC082 Double Compression configurations. The HMI range specifies nickel-plated brass construction and BSC entry thread.

2. What is the difference between HMI SC082 and DC082?

SC082 is the Single Compression version and grips the outer cable sheath. DC082 is the Double Compression version specified for armoured cables; it seals/grips the inner and outer sheath and uses a cone and ring to clamp the armour.

3. Does an 82mm Cable Gland fit an 82mm cable?

Not necessarily. The 82mm (3-1/4″) designation is a nominal gland size. The actual cable OD must be checked against the manufacturer’s applicable cable-clamping dimensions. Published selection charts demonstrate that nominal gland size and cable OD are separate specifications.

4. How do I select the correct HMI 82mm Cable Gland?

Check the actual cable OD, cable construction, armoured/unarmoured status, compression type, thread and installation requirements. Do not select the gland using conductor sq.mm alone.

5. Is HMI SC082 suitable for armoured cable?

HMI’s Single Compression range is specified for armoured and unarmoured cables. The particular cable OD and installation should still be verified before selection.

6. Is HMI DC082 suitable for armoured cable?

Yes. HMI specifies the Double Compression range for armoured cables, with the cone and ring arrangement used to clamp the armour.

7. What thread does the HMI 82mm Cable Gland use?

HMI specifies BSC (British Standard Conduit) entry thread for its Single and Double Compression cable-gland ranges.

8. Is 82mm the same as an 82 sq.mm cable?

No. 82mm is a dimensional gland designation, while sq.mm normally describes conductor cross-sectional area. They represent different measurements and should not be confused.

9. What material is the HMI 82mm Cable Gland made from?

HMI specifies nickel-plated brass for its Single and Double Compression cable-gland ranges.

10. Which is better: Single Compression or Double Compression?

Neither is universally “better.” The correct choice depends on the cable construction and installation specification. Single Compression and Double Compression perform different cable-entry functions, so selection should be based on the actual application.

11. Why is cable OD important when buying an 82mm Cable Gland?

The gland’s sealing and gripping arrangement works around the external cable dimensions. Therefore, the actual cable OD is essential for confirming compatibility. Manufacturer selection charts commonly use cable overall diameter as a key selection parameter.

12. Can I select the HMI 82mm Cable Gland only by cable conductor size?

No. Conductor size does not by itself establish the correct gland. Check the complete cable OD, cable construction, armour, thread and gland manufacturer’s selection information.
