Types of Rubber Seals
O-Rings
O-Rings are circular seals commonly used in a variety of applications, including hydraulic systems and automotive components. They are made from materials such as NBR (Nitrile Butadiene Rubber), FKM (Fluoroelastomer), and EPDM (Ethylene Propylene Diene Monomer). O-Rings are known for their versatility and reliability, making them a go-to choice for many engineers and manufacturers. Their simple design allows for easy installation and effective sealing against fluids and gases.
Gaskets
Gaskets serve as barriers between two surfaces to prevent leaks and contamination. They are often used in flange connections and machinery. Materials like EPDM and Buna-N provide excellent compression and adaptability to different shapes and sizes. Custom gaskets can be designed to meet specific industry needs, ensuring optimal sealing performance in various applications.
Grommets
Grommets are used to protect cables and wires from abrasion and moisture. Made from materials like silicone and EPDM, grommets are commonly found in automotive applications, electrical devices, and appliances. Their ability to insulate and shield components makes them essential for maintaining functionality and safety in various environments.
Quad Rings
Quad Rings, also known as X-rings, offer enhanced sealing capabilities compared to traditional O-Rings. They are particularly effective in dynamic sealing applications, such as hydraulic and pneumatic systems. Made from materials like NBR and FKM, Quad Rings reduce extrusion and improve the overall sealing performance, making them a preferred choice for high-pressure applications.
Bulb Seals
Bulb Seals are flexible rubber seals commonly used in automotive sunroofs, window seals, and door seals. Made from EPDM, these seals provide excellent resistance to weather conditions and noise, ensuring a comfortable interior environment. Their unique design allows them to conform to the contours of the surfaces they are sealing, which enhances their effectiveness.
Custom Molded Seals
Custom molded seals are tailored to meet specific requirements across various industries. These seals can be made from a variety of materials and can be designed for unique applications, ensuring a perfect fit and optimal performance. Custom seals are ideal for specialized equipment, machinery, and components where standard seals may not suffice.
