Enclosure Gaskets
Enclosure gaskets are sealing components used in various industries and applications to provide a leak-tight seal between two surfaces. These gaskets are typically made from various materials, such as rubber, silicone, foam, or elastomers, and they are designed to prevent the ingress of dust, water, moisture, gasses, or other contaminants into an enclosure, and noise or other forms of interference generated from internal components. Enclosure gaskets are commonly used in some fields where it’s crucial to maintain environmental and ingress protection.
What’s more, we have many professional ways to customize your enclosure gaskets like extrusion, dies, splicing molds, and corner molds, so our enclosure gaskets are suitable for either wall-mount or free-stand/floor-mount enclosures.
We have many forms of enclosure gaskets in stock like long straight lengths, coil form, form-cured lengths, and cut pieces. As far as shapes of enclosure gaskets, there are square, oval, rectangle, and circular for you to choose.
The primary purposes of enclosure gaskets are as follows
Environmental Protection: Enclosure gaskets help protect the internal components of a device or equipment from environmental factors such as dust, dirt, water, and humidity. This holds significant importance, especially when it comes to electronic and electrical devices, to guarantee their effective operation and durability.
Ingress Protection: Enclosure gaskets play a key role in achieving specific ingress protection (IP) ratings, which define the degree of protection an enclosure offers against the intrusion of solids and liquids. For example, an IP68-rated enclosure is highly resistant to dust and can endure prolonged submersion without permitting water penetration.
EMI/RFI Shielding: In some applications, specialized gaskets made from conductive materials may be used to provide electromagnetic interference (EMI) or radio frequency interference (RFI) shielding. These gaskets help prevent unwanted electromagnetic signals from entering or leaving an enclosure, ensuring the proper functioning of sensitive electronic equipment.
Vibration and Shock Absorption: Gaskets can also serve as vibration and shock-absorbing components, reducing the impact of mechanical vibrations and shocks on the internal components of an enclosure. This is important for equipment used in rugged environments.
Special customization service of enclosure gaskets
Enclosure gaskets come in various shapes, sizes, and materials to suit the specific needs of different applications. Some common types of enclosure gaskets include:
O-rings: Circular gaskets with a cross-sectional shape resembling the letter “O.” They are commonly used in cylindrical or round sealing applications.
Gasket strips or tapes: Flexible strips or tapes made from rubber or foam that can be cut to the desired length and shape.
Solid gaskets: Solid sheets or molded gaskets made from materials like silicone or neoprene, used for sealing flat surfaces.
Extruded gaskets: Gaskets with custom profiles that are created by extruding material through a die to match the contours of the enclosure.
The choice of enclosure gasket material and design depends on factors such as the intended application, environmental conditions, temperature range, and the required level of protection against contaminants and moisture. Properly selected and installed enclosure gaskets are crucial for ensuring the reliability and performance of enclosed equipment.
