Blanking plugs
Blanking plugs are plastic closures used to seal unused threaded openings in cable glands or enclosures. They prevent dirt, dust, or moisture from entering, which is essential for maintaining the protection rating and the lifespan of electrical installations.
Function and benefits
The primary function of blanking plugs is to protect unused threaded openings from external influences such as water, dust, and chemicals. This helps maintain the protection rating (up to IP68/IP69K) and prevents corrosion or damage to internal components. Additionally, they provide a neat and professional finish to installations, contributing to the overall quality and reliability of the system.
Applications
Blanking plugs are mainly used in electrical engineering and industrial installations, where cable glands are used to pass cables through enclosures. They are ideal for situations where threaded openings are temporarily or permanently not in use, such as during expansions or modifications of installations. They are also used in control cabinets, distribution panels, and other electrical enclosures to seal unused connections.
Materials
Our blanking plugs are made of polyamide PA6 GF30, a plastic known for its strength, durability, and chemical resistance. This material choice ensures a reliable and long-lasting seal, even under harsh conditions. The plugs are available in two colors: black (RAL 9005) and light grey (RAL 7035), so they can fit various environments and aesthetic preferences.
Properties
Our plastic blanking plugs provide excellent protection against external influences, ensuring that the internal components of the installation remain secure. They are resistant to a wide temperature range from -40 to +100°C and meet the requirements of protection classes IP68 and IP69K. This makes them suitable for both indoor and outdoor applications, even under extreme conditions.
Dimensions
Blanking plugs are available in various metric sizes, including M12, M16, M20, M25, M32, M40, M50, and M63. Each size is designed to fit perfectly with the corresponding threaded openings, ensuring optimal blanking. The plugs are available in packages of 50 units, providing efficient stock management and cost savings for large-scale applications.
