D-Section Rubber Seals: A Versatile Solution for Sealing and Protection

April 25, 2025

D-section rubber profiles are some of the most commonly used rubber seals, particularly in the automotive, construction, and appliances industries. The distinctive shape of extruded D seals protects components, prevents leaks, and ensures optimal performance. Here’s how Elbex creates high-quality D-section rubber seals for your needs.


What are D-Section Rubber Seals?


A D-section rubber seal is a half-round rubber seal with a distinctive D-shaped cross-section. D-seals are available in a wide range of height and width variations to meet the needs of different applications. Many also utilize adhesive backing for easier installation, or metal inserts for added structural support.


When to Use D-Section Seals


D-seals are especially common in the automotive and construction industries, where they are used to seal doors, windows, and hatches. They create watertight seals that can also reduce noise and vibrations and improve insulation, protecting equipment and components from dust, moisture, and debris.


Because of these and other environmental hazards, D-seal design and material selection must account for temperature, pressure, chemicals, the material’s compatibility with the sealing surface, and the required force to create the seal.


Advantages of D-Section Rubber Seals


D-section rubber seals offer superior sealing performance. When the D-seal is compressed, it creates a tight seal that keeps out leaks and contaminants. Since D-seals can be adapted to different shapes and sizes, they are extremely versatile. They are also typically very easy to install, often using simple press-fit or adhesive applications.


When high-quality materials are used, you can count on D-seals to offer extended durability, while still being more cost-effective than other sealing solutions. The combination of performance and value makes them the go-to choice for many sealing applications.

Sealing in Savings: Elbex's High-Performance Refrigerator and Freezer Door Gaskets

May 16, 2025
Freezer and refrigerator door gaskets play an essential role in ensuring that these appliances are energy efficient, preserve food, and prevent frost buildup. Worn or damaged gaskets can result in significant energy loss, as well as temperature fluctuations that lead to food spoilage – which can prove costly in both residential and commercial kitchens. As a leading manufacturer of high-quality, durable air barrier seals for refrigerators and freezers, Elbex ensures that your appliances deliver the quality performance your own customers deserve. The Importance of Airtight Seals in Refrigeration Properly functioning gaskets are vital in any quality refrigerator or freezer. Properly functioning gaskets prevent the escape of cold air and the entry of warm, humid air. This reduces the compressor’s workload and lowers the appliance’s energy consumption. Keeping out humid air also prevents frost buildup inside freezers, which is a common maintenance issue. Even more importantly, maintaining consistent internal temperatures extends the shelf life and quality of stored food, preventing spoilage. By reducing energy consumption and food waste, airtight seals can greatly lower costs. Elbex’s Expertise in Refrigerator and Freezer Door Gaskets At Elbex, we bring extensive experience with refrigerator and freezer door gaskets to create airtight seals specifically designed for your appliances. We use our knowledge of various elastomers to select materials like flexible PVC, TPE, and silicone that remain flexible at low temperatures, resist tearing and wear, and are food-grade compliant. We also use state-of-the-art extrusion and molding processes that ensure tight tolerances, consistent quality, and superior sealing performance. Our airtight barriers are designed for durability and longevity, even for demanding or unique applications. We can also collaborate with your manufacturing team to develop custom gasket profiles that match the specific requirements of your refrigerator and freezer models and their door configurations. Benefits of Choosing Elbex’s Refrigerator and Freezer Door Gaskets When you work with Elbex, you can have confidence that our precision-designed seals will deliver consistent, long-lasting performance. From materials selection to design, our gaskets will resist cracking, tearing, and compression set, even on frequently used refrigerators and freezers. We also ensure that our gaskets are easy to install and replace, minimizing downtime when maintenance is needed. And with our customization options, we can tailor everything from aesthetics to functionality based on your specific needs. At Elbex, we are committed to providing high-quality, custom-designed refrigerator door gaskets and air barrier seals for refrigerators and freezers.

Unlocking the Power of Rubber: Understanding Elastomer Properties for Optimal Performance

April 18, 2025
Rubber elastomers are used in countless industries and applications, from automobiles to architecture. However, understanding the physical properties of rubber elastomers is essential for getting the right material for the right application. At Elbex, our deep understanding of elastomer characteristics ensures you’ll get the right match for your project. Key Properties of Rubber Elastomers The following properties are critical when considering which rubber elastomer is right for your application: Elasticity and resilience: Rubber has the ability to deform under stress and then return to its original shape. Important in vibration damping and shock absorption. Tensile strength and elongation: The ability to stretch and withstand pulling forces without breaking. Hardness: Is the rubber flexible or rigid? This affects its abrasion resistance and compression set. Compression set: Compression set is a permanent deformation that occurs after prolonged compression. Long-term sealing or cushioning applications require a low compression set. Temperature resistance: The elastomer’s ability to withstand high and/or low temperatures – important when considering the application’s operating temperature range. Chemical resistance: An elastomer’s resistance to any chemicals, oils, and solvents that might be present in its operating environment. Weathering and ozone resistance: The elastomer’s ability to withstand sunlight, ozone, and other environmental factors are especially important for outdoor applications. Common Types of Elastomers and Their Applications The following are some of the most common types of rubber elastomers: Natural Rubber (NR): Used for tires, footwear, and adhesives, natural rubber is known for offering excellent elasticity, resilience, and tear resistance. Styrene-Butadiene Rubber (SBR): This cost-effective elastomer offers good abrasion resistance. It is commonly used in tires, conveyor belts, and footwear. Ethylene Propylene Diene Monomer (EPDM): EPDM offers excellent resistance to weathering, ozone, and heat. As a result, it is the go-to option for rubber roofing, as well as automotive seals and hoses. Nitrile Rubber (NBR): With resistance to oil, fuel, and chemicals, nitrile is commonly used for automotive and industrial seals and gaskets. Silicone Rubber (VMQ): Usable in a wide range of temperatures, while also offering excellent electrical insulation properties and biocompatibility, silicone is a top choice for medical devices, cookware, and electronics. Neoprene Rubber (CR): Neoprene’s flame resistance, oil resistance, and weather resistance means it is frequently used for applications such as wetsuits, adhesives, and automotive components.
