Types of KO Seals
Gasketed KO Seals
Gasketed KO seals are designed to prevent liquids and gases from entering or escaping electrical boxes. Typically made from steel, these seals provide a robust solution for outdoor installations and areas prone to moisture. Their oil-tight feature is particularly beneficial in environments where oil exposure is a concern.
Snap-In KO Seals
Snap-in KO seals are a popular choice for quick and easy installations. Made from durable plastic, these seals are designed to fit snugly into knockout holes without the need for additional tools. Their lightweight nature makes them ideal for residential and light commercial applications where speed is essential.
Screw Type KO Seals
For heavy-duty applications, screw-type KO seals are preferred. These seals use screws for installation, ensuring a secure fit in demanding environments. Typically made from steel, they are ideal for industrial applications where strength and reliability are paramount.
KO Connectors
KO connectors serve as a bridge between conduits and electrical boxes. Made from aluminum, these connectors are lightweight yet durable, providing an effective solution for connecting conduits in various electrical installations.
Packaged KO Seals
Bulk purchasing options, such as packs of four KO seals, are available for those who require multiple seals for larger projects. This option is both cost-effective and convenient, streamlining the procurement process.
Applications of KO Seals
Residential
In residential settings, KO seals are commonly used in electrical boxes to maintain safety and aesthetic appeal. They protect against dust and pests while ensuring that electrical systems remain secure.
Commercial
Commercial installations often require more robust solutions due to higher electrical demands. Gasketed and screw-type KO seals are frequently used in these applications to ensure compliance with safety standards.
Industrial
Industries that deal with hazardous materials benefit from KO seals that offer superior protection. Heavy-duty seals and connectors are essential in these environments to prevent any external elements from interfering with electrical systems.
Outdoor
For outdoor electrical installations, weather-resistant KO seals are critical. The gasketed seals provide oil-tight protection, ensuring that moisture does not compromise the integrity of electrical systems.
