Colored Strain Relief Cable Gland Nylon 6 (Polyamide 6/PA6), PG13.5 (Ø 6-12mm &

Product Specification

What are colored spiral nylon cable glands?

Colored spiral nylon cable glands are a type of cable-entry and strain-relief device made primarily from engineering nylon 6 (polyamide 6), with a flexible spiral or coiled section at the cable outlet. It is installed where a cable passes through an electrical enclosure, junction box, control cabinet, machine housing, or other equipment.

These spiral cable glands perform two functions at the same time:

Cable sealing and retention — the sealing ring grips the cable and helps prevent dust and water from entering the enclosure.

Bending and strain protection — the spiral tail provides a flexible transition between the fixed gland and the cable, reducing sharp bending and mechanical stress at the cable exit.

What features do the colored spiral cable glands have?

1. Spiral bend protection

This is the defining feature.

Conventional straight cable glands hold and seal the cable, but the cable can still form a relatively sharp bend immediately outside the cable gland. The spiral cable glands create a longer, flexible bend transition, helping distribute bending stress over a larger section of cable.

They are designed to intend to reduce conductor fatigue, protect against excessive bending, and provide additional flexibility and strain relief.

This is particularly useful for:

• Moving cables
• Equipment with vibration
• Hand-operated equipment
• Machine wiring
• Cables routed through tight spaces
• Applications where the cable frequently bends near the enclosure

2. Water and dust sealing

Our spiral cable glands are available with IP68 / IP69K protection, they are dust, water resistant, good sealing performance, protecting your electrical boxes against ingress of liquids.

3. Lightweight construction

Nylon 6 (polyamide 6) is considerably lighter than metal cable glands. This can be useful when equipment has many cable entries or when reducing overall assembly weight matters.

4. Electrical insulation

Unlike metal cable glands, nylon version is electrically insulating. This can be advantageous in many low-voltage electrical and electronic installations where electrical isolation and corrosion resistance are desirable.

5. Corrosion resistance

Nylon version does not rust like steel version and is naturally suitable for many humid environments. However, resistance to specific chemicals, solvents, oils, UV exposure, and outdoor weathering depends on the particular nylon formulation and seal material.

6. Vibration and movement resistance

The spiral design can make the cable exit less susceptible to stress concentration caused by vibration and movement. These cable glands are for moving or flexible cables and vibration protection.

7. Color customization

Color can provide both visual and organizational benefits.

We offer standard colors such as black and gray, while other colors can be custom-produced. RAL color references are commonly used for specifying enclosure and cable-gland colors.

Why do we use the colored spiral nylon cable gland?

There are really two separate reasons: the spiral design and the color.

Spiral design: protect the cable

The primary mechanical reason is to reduce bending stress and improve strain relief.

For example:

Without spiral protection:
Cable → sharp bending point → high local stress → insulation/core fatigue

With spiral protection:
Cable → flexible spiral transition → distributed bending → lower local stress

This can be especially valuable when cables are pulled, moved, vibrated, or repeatedly bent.

Color: improve identification

Color is usually not what creates the sealing or mechanical performance. Instead, it can make an installation easier to identify, organize, inspect, and maintain.

For example, a project might use:

These color assignments are project-specific unless an applicable standard or plant specification defines them. A blue gland, for example, should not automatically be interpreted as a particular electrical function.

Color can also be used to:

• Match the enclosure
• Distinguish different cable systems
• Simplify maintenance
• Improve visual inspection
• Support OEM product design
• Create a consistent product appearance

Where are colored spiral nylon cable glands used?

They are particularly useful where cable bending protection and visual identification are both valuable.

Industrial automation

Used in:

• Control cabinets
• Sensors
• Actuators
• PLC equipment
• Machine wiring
• Automated production equipment

The spiral tail helps protect cables where machinery creates movement and vibration.

Machinery and equipment

Common for:

• CNC machines
• Packaging machinery
• Textile machinery
• Material-handling equipment
• Assembly machines
• Pumps and industrial equipment

Robotics and motion systems

They can be useful at cable exits where there is flexing, although high-cycle robotic applications require careful consideration of dynamic cable specifications.

Electrical and control panels

The cable glands provide cable retention and sealing at enclosure entries. Different colors may also make cable groups easier to identify.

Outdoor electrical equipment

Potential applications include:

• Outdoor control boxes
• Lighting equipment
• Solar equipment
• Communication equipment
• Electrical junction boxes

The actual suitability depends on UV resistance, temperature, IP rating, and the particular cable-gland material/seal combination.

Transportation and mobile equipment

The flexible structure may be useful on equipment exposed to vibration or cable movement.

Handheld and portable equipment

We specifically identify spiral cable glands for handheld or portable devices because of their additional flexibility and strain relief.

Conclusion

The colored spiral nylon cable glands combine the functions of a conventional nylon cable gland with an extended spiral bend-protection tail. Its main technical purpose is to provide sealing, cable retention, strain relief, and improved protection against bending-related cable damage. Commercial examples use PA6 or PA6.6 and are available with IP68 ratings, different thread systems, and various cable clamping ranges.

The color is mainly an identification, organization, customization, and appearance feature, while the spiral structure is the key functional difference.

For industrial automation, machinery, control cabinets, outdoor electrical equipment, portable equipment, and applications where cables bend close to the enclosure, this type of cable gland can provide a practical combination of cable protection, sealing, flexibility, lightweight construction, and visual identification.
