Cable gland (mufa) Detal-met M20 20 mm for cable entry and conduit connection

Detal-met Mufa PP 20mm - M20 is a polypropylene cable gland designed for secure cable entry and conduit connection with a 20 mm thread/diameter. The gland creates a mechanical connection between cables and enclosures or conduits, helps to relieve strain on conductors and preserves cable routing integrity in electrical installations and junction boxes. Its plastic construction provides resistance to corrosion and electrical insulation where a durable non-metallic solution is required.

Advantages

The polypropylene construction offers chemical and corrosion resistance while remaining lightweight. The M20 size provides a standard thread for many conduit systems, allowing straightforward installation and a reliable seal at the entry point. Its design reduces mechanical stress on cables, improves cable management at enclosures and junctions, and is suitable for environments where a non-conductive gland is preferred.

Suitable for

• Cable entry into electrical enclosures and junction boxes
• Connection of flexible conduits and rigid conduit systems with M20 thread
• Indoor and dry location wiring where plastic glands are acceptable
• Low-voltage installations requiring strain relief and routing control

Key specifications

• Material: polypropylene (PP)
• Thread/nominal diameter: 20 mm (M20-compatible)
• Function: mechanical cable gland for strain relief and sealing at cable entry
• Application: cable-to-enclosure and cable-to-conduit connection
• Electrical property: non-conductive body providing electrical insulation
• Environmental property: corrosion-resistant plastic construction

How to use

Prepare the enclosure or conduit entry with a compatible M20 thread or hole. Insert the gland into the entry and secure it by tightening to the enclosure or conduit according to standard installation practice. Pass the cable through the gland, then tighten the internal locking mechanism or nut to provide strain relief and maintain cable position. Ensure the gland is fitted so cable insulation is not damaged and that the connection achieves the required mechanical support.

Usage recommendations

Use the Detal-met M20 gland in installations where a non-metallic, corrosion-resistant entry component is appropriate. Check compatibility with conduit threads and ensure the cable diameter matches the gland’s clamping range. Avoid use in high-temperature or harsh chemical environments beyond polypropylene specifications; follow local installation standards and safety regulations when fitting and testing the cable entry.
