Lapp SKINDICHT BLK-GL-M M20x1.5 Polyamide Blanking Plug with O-Ring, Dark Grey, IP68

The Lapp SKINDICHT BLK-GL-M M20x1.5 polyamide blanking plug is a professional-grade component engineered to seal unused threaded entries in electrical enclosures, junction boxes, and machinery housings. Constructed from high-quality polyamide, this plug ensures long-term durability and resistance to environmental factors. The inclusion of a pre-installed O-ring guarantees a secure, airtight, and watertight seal, maintaining the integrity of your electrical systems.

Advantages

This blanking plug offers exceptional reliability due to its robust polyamide construction, which provides excellent mechanical strength and chemical resistance. The integrated O-ring simplifies the installation process by eliminating the need for additional sealing components while ensuring a high level of ingress protection. Its dark grey finish provides a professional appearance that integrates seamlessly with standard industrial equipment, and the M20x1.5 thread ensures compatibility with a wide range of metric-threaded ports.

Suitable for

• Sealing unused cable entries in junction boxes
• Protecting internal components in industrial control panels
• Closing off threaded holes in electrical enclosures
• Applications requiring IP68 protection against dust and water

When it may not be suitable

This product is designed for standard metric M20x1.5 threaded holes and will not fit ports with different thread sizes or types, such as PG or NPT threads. It is intended for use in environments within the specified temperature and pressure limits of polyamide materials and may not be suitable for extreme high-heat or highly corrosive chemical environments where metallic plugs are required.

Key specifications

• Thread size: M20x1.5
• Material: Polyamide
• Protection rating: IP68
• Color: Dark Grey
• Includes integrated O-ring

How to use

To install the blanking plug, ensure the threaded hole is clean and free of debris. Insert the plug into the M20x1.5 threaded opening and rotate it clockwise by hand or with a suitable tool until the O-ring is firmly compressed against the surface of the enclosure. Do not overtighten, as this may damage the plastic threads. The plug should be seated flush against the housing to ensure the IP68 seal is fully effective.

What to consider before purchase

• Verify that your enclosure port is exactly M20x1.5
• Check the wall thickness of your enclosure to ensure compatibility
• Confirm the environmental conditions do not exceed the material limits of polyamide

Usage recommendations

For optimal performance and to maintain the IP68 rating, ensure the surface around the threaded hole is flat and free from burrs or paint buildup that could compromise the O-ring seal.
