Cable Gland Bettermann V‑TEC VM20 M20 Polyamide IP68, Light Grey, Pack of 50

The Bettermann V-TEC VM20 polyamide cable gland with M20 thread and IP68 protection is designed to secure and seal cables where they enter enclosures. Supplied as a pack of 50 in a light grey finish, this gland provides mechanical strain relief and environmental sealing for electrical and instrumentation cables in industrial, commercial and outdoor installations. Its compact M20 size and durable polyamide construction make it suitable for many cable routing and termination points where a water- and dust-tight entry is required.

Advantages

The polyamide material offers good mechanical strength and resistance to many common chemicals, while remaining lightweight. The IP68 rating ensures long-term protection against dust ingress and water immersion, making it suitable for wet or exposed locations. The M20 threaded design enables straightforward installation into compatible enclosures and panels, and the pack quantity of 50 supports repeat installations or stock for maintenance tasks.

Suitable for

• Sealing and strain-relief of single and multi-core cables with compatible outer diameters in industrial control cabinets and junction boxes
• Cable entries on outdoor enclosures, lighting columns and equipment exposed to rain or dust
• Routine maintenance and repeat installations where bulk quantities are required

When it may not be suitable

This M20 polyamide gland is optimized for general-purpose cable sealing and strain relief; it may not be suitable where higher mechanical impact resistance, UV stability beyond standard polyamide performance, or specific chemical compatibility is required. For applications demanding specialised sealing for very large cable diameters, hazardous atmospheres, or extreme temperature ranges, select a gland specifically rated for those conditions.

Key specifications

• Thread size: M20
• Material: polyamide (plastic)
• Ingress protection: IP68
• Finish / colour: light grey
• Pack quantity: 50 pieces

How to use

Drill or prepare an M20 threaded entry in the enclosure or panel, insert the gland body and tighten according to enclosure requirements. Pass the cable through the gland, then tighten the sealing nut to provide strain relief and an environmental seal around the cable outer sheath. Ensure cable diameter is compatible with the gland’s sealing range and that any required washers or locking devices are fitted to maintain the IP68 rating. Follow local electrical codes and safety procedures during installation.

What to consider before purchase

• Verify that the cable outer diameter falls within the gland’s accepted sealing range
• Confirm M20 thread compatibility with the enclosure or panel entries you will use
• Assess whether polyamide material and IP68 level meet environmental and chemical resistance needs

Usage recommendations

Use this gland for standard cable entry points in non-hazardous industrial and outdoor environments. For best sealing performance, replace glands showing damage or wear and check that the sealing nut is tightened to the manufacturer’s guidance; keep spare pieces from the pack for maintenance tasks.
