Spiral Cable Glands for Bend Protection & Strain Relief

Flexible Spiral Protection. Reduced Cable Stress. Reliable Sealing.

Spiral cable glands feature an extended flexible spiral tail that helps protect cables from sharp bending at equipment entry points. Unlike standard straight cable glands, the spiral design provides additional support where a cable exits the gland, helping reduce localized bending stress and the risk of cable jacket damage.

Flexible Spiral Design for Cable Protection

When a cable is frequently moved, pulled or bent, stress can concentrate near the rigid cable entry. The integrated spiral section supports a more gradual bending transition, helping reduce sharp bends and stress concentration.

Key benefits include:

Anti-Kink Protection: Helps prevent excessive bending near the cable entry.
Reduced Cable Stress: Distributes bending over a longer section of cable.
Cable Jacket Protection: Helps reduce damage caused by repeated sharp bending.
Secure Cable Grip: Compression sealing helps limit cable movement and pulling at the entry.
Waterproof Sealing: Protects cable entries against water and dust under specified installation conditions.

Designed for Moving & Flexible Cables

Typical applications include:

Handheld Equipment: Cable exit protection for portable electrical tools and devices.
Industrial Machinery: Cable connections exposed to equipment movement or vibration.
Robotics & Automation: Additional bend protection for suitably rated flexible cables.
Stage Lighting & Audio: Cable connections on frequently repositioned equipment.
Portable Industrial Equipment: Cable protection where equipment is regularly moved or handled.

Multiple Thread & Sealing Options

Available in PG, Metric (M), NPT and G thread types for different equipment interfaces.

Standard and reduced-range (T) sealing options accommodate different cable outside diameters.

Choose the Right Spiral Cable Gland

Select according to the mounting thread, cable outside diameter, cable flexibility, movement conditions and required sealing protection.

Free samples are available for checking installation fit and cable bending behavior.

Frequently Asked Questions

1. What is a spiral cable gland?

A spiral cable gland is a cable entry fitting with an extended flexible spiral section designed to provide additional bend protection and strain relief at the cable exit.

2. What is the advantage of the spiral design?

The spiral tail helps support the cable near the entry point and reduce sharp bending and localized mechanical stress.

3. Are spiral cable glands suitable for moving equipment?

Yes. They are useful for handheld devices, moving machinery and equipment with flexible cables. The cable’s minimum bending radius and movement requirements must still be observed.

4. Are spiral cable glands waterproof?

IP68-rated versions are available. Actual waterproof performance depends on the specified test conditions, cable diameter, sealing accessories and correct installation.

5. Which thread types are available?

PG, Metric (M), G (BSPP) and NPT thread options are available, with standard and reduced cable clamping ranges.
