Metric Nylon Cable Glands (M) – IP68 Waterproof Cable Connectors

Reliable Cable Sealing, Secure Strain Relief & Precise Metric Thread Fit

Metric nylon cable glands provide waterproof cable entry and secure cable gripping for electrical enclosures, industrial machinery and automation equipment. Manufactured with PA66 nylon bodies and NBR sealing components, they are available in multiple metric thread sizes and cable clamping ranges.

IP68 Cable Entry Protection

The compression sealing design helps prevent water and dust from entering electrical enclosures through cable entry points. Correct cable diameter, sealing components and installation are essential for achieving the specified IP protection.

Secure Cable Grip & Strain Relief

The tightening nut compresses the sealing mechanism around the cable jacket, helping reduce movement and strain at the cable entry. This is especially useful for electrical control panels, machine housings and industrial equipment.

Metric Thread Design for Easy Integration

Available in metric thread sizes from M12×1.5 to M63×1.5, including additional intermediate sizes. Standard and reduced clamping ranges are offered for different cable outside diameters, providing installation flexibility without changing the selected thread size.

Typical Applications

Electrical Cabinets: Waterproof cable entries for control panels and junction boxes.
Industrial Automation: Secure connections for sensors, signal and control cables.
Machinery & Equipment: Cable sealing and strain relief at equipment housings.
OEM Electrical Enclosures: Metric threaded cable entries for equipment production.
Outdoor Installations: Weather-exposed cable entries using appropriately rated materials.

Choose the Correct Cable Gland

For proper installation, confirm:

Metric thread size and pitch
Cable outside diameter and clamping range
Mounting hole and thread length (The installing hole should be a little bigger than the thread diameter)
Installation environment and IP requirements

Provide your required thread size, cable diameter, application and quantity for product selection and quotation.

Frequently Asked Questions

1. What is a metric cable gland?

A metric cable gland is a cable entry fitting with a metric mounting thread, designed to seal and secure cables entering electrical enclosures or equipment.

2. What does M20×1.5 mean?

M20 indicates a nominal thread diameter of 20 mm, while 1.5 indicates the thread pitch in millimeters. It does not specify the cable diameter.

3. What is the difference between M20 and M20T cable glands?

Both use the M20×1.5 thread. The standard version fits 6–12 mm cables, while the reduced-range version fits 5–9 mm cables.

4. Can metric cable glands replace PG cable glands?

Not directly. Metric and PG threads have different dimensions and profiles. Always confirm the enclosure thread or use a suitable thread adapter.

5. Are metric nylon cable glands suitable for outdoor use?

They can be used outdoors when the selected materials, cable diameter and installation conditions are suitable. UV resistance and waterproof performance should be confirmed for the application.
