Enclosure Hole Seals

Hole seals for enclosures are specialized components that effectively seal unused holes in enclosure walls. They help keep contaminants like dust, dirt, oil and water out of extra pushbutton holes and conduit openings. So if there's no reason for a hole to exist, it's better to seal it up tightly and securely.

Installing hole seals is a simple but vital procedure that guarantees a watertight seal. It enhances the enclosure's protection from oil and water penetration. This is especially important in environments where enclosures are exposed to liquids or where they are located outdoors. A seal for holes also helps to maintain the airtightness of an enclosure, which is crucial in preventing the entry of contaminants that could damage the enclosed equipment.

FAQs

What material is ideal to seal extra pushbutton holes and knockout openings in outdoor enclosures?

Weatherproof plugs or seals made from durable materials such as stainless steel, aluminum, or UV-resistant rubber are suitable for sealing extra pushbutton holes and knockout openings in outdoor enclosures to protect against moisture, dust, and corrosion.

Industrial Enclosure Accessories and Modifications 

Common modifications or accessories that are used to enhance electrical cabinets.

Lighting kits. Lighting kits are often used in outdoor applications. There are many different styles of lighting kits that can be used, but LEDs have become the preferred lighting solution in the past several years.

Pressure switches. Pressure switches operate on a spring and react to the cabinet door opening and closing. They can be used for lights, intrusions alarms and exhaust fans.

Passive air vents. Passive air vents allow natural air circulation to flow through a cabinet providing proper ventilation.

Enclosure fans. Enclosure air fans are used when more ventilation is required. The size of the fan will depend on the size of the enclosure as well as the amount of air that needs to be circulated.

Air conditioners. Air conditioners are used when ambient air circulation is inadequate to cool the cabinet. The air conditioner size will depend on the enclosure size, ambient air temperature and heat generated within the cabinet.

Heaters. Heaters are used when a cabinet is located in areas that may be exposed to cold temperatures.

Locking mechanisms. Locking mechanisms are used to secure cabinets.

Conduit hole seals. Conduit hole seals are used on cabinets that have holes that need to be plugged after conduit has been removed.
