Elbex - Custom Rubber Extrusions

At ELBEX, we work tirelessly to exceed customer expectations and manufacture high-quality rubber extrusions. A big part of our ability to meet these goals comes from the wide variety of profiles we can manufacture — including bulb seals, bumpers, and D-Section profiles.

Bulb Seals

Bulb seals create a seal by taking on the shape of the channel or void they need to fill. To that end, we offer several standard bulb seal extrusions, while also using our in-house team to develop custom bulb seals when necessary. We use different materials based on the needs of the application or environment to ensure reliable performance.

Bumpers

Bumper extrusions form a cushion that reduces movement and vibrations, especially from impacts. These extrusions are helpful in applications where the movement of the equipment has the potential to damage other property or the equipment itself. We typically use EPDM for bumper profiles because of its high abrasion resistance.

D-Section Profiles

D-Section profiles are similar to bulb seals in that they are often used to fill voids or create a seal between two different surfaces. Their name comes from their distinctive shape, which looks like the letter “D.” They typically use a pressure-sensitive adhesive that is applied to the flat end to remain stationary. Though used in a wide range of industries and applications, they are most often used to create a weather seal around windows and doors.

No matter what type of extrusion you need for your application, you can trust our team to perfectly meet your project requirements. Contact us today to learn more about how we can turn your application into a reality.

Across industries, reliable seals that can handle water, air, and temperature fluctuations are essential. As an expert manufacturer of rubber bulb seals and specialized silicone rubber seals that can be used as bulb gasket seals, Elbex helps you create superior barriers for a wide range of manufacturing applications. The Unique Design and Sealing Power of Bulb Seals Bulb seals get their name from their unique design, which includes a mounting mechanism (base), as well as a compressible bulb section. After it has been put in place, the bulb section compresses against the surrounding surface area to fill a void or gap. This creates a tight, powerful seal that blocks air, dust, water, and other contaminants. Elbex's Expertise in Custom Bulb Seal Manufacturing Elbex’s custom bulb seal manufacturing expertise ensures that your rubber bulb seals meet all performance requirements for strong, durable results. This starts with our knowledge of which rubber materials work best for different applications and environmental factors. For example, silicone rubber seals work well for applications requiring extreme temperature resistance, flexibility, and resistance to environmental factors. Our custom design and engineering capabilities enable us to accommodate nearly any application, ensuring a perfect fit and reliable performance based on your unique specifications. Comprehensive quality control further ensures that your rubber seal will meet and even exceed expectations, achieving proper compression while resisting issues like compression set. Versatile Applications Across Industries Rubber seals are found in many different industries, highlighting the versatile nature of these components. For example, rubber seals are most commonly used around doors, windows, and hatches to provide a tight seal against air, sound, and dust (including in vehicles and appliances). However, bulb gasket seals are also used to create tight water barriers in marine applications, outdoor electrical enclosures, and storage compartments. Silicone rubber seals can also help contain extreme heat or cold in industrial mixing, processing, and food service applications. Why Elbex is the Premier Choice for Bulb Seals If you need bulb seals, make Elbex your manufacturing partner. With unmatched customization options, comprehensive material expertise and engineering support, and guaranteed quality, our team will help your application succeed. Contact us today to discuss your specific application needs and learn more about the sealing power of our custom-designed seals.

Today’s appliances need to perform at a higher standard than ever – and seals and gaskets play a vital role in making that possible. Specialized appliance gaskets and appliance seals deliver reliable barriers against heat, cold, and other hazards. As a leading provider of high-quality appliance rubber extrusions, Elbex’s custom extruded rubber gaskets for appliance manufacturing will provide the performance you need. The Essential Role of Rubber in Appliance Performance Gaskets and seals create a reliable barrier that keeps appliances functioning properly. These barriers fill a wide range of roles, such as preventing leaks in washing machines and dishwashers, helping refrigerators and ovens maintain desired temperatures, and securing components and eliminating vibrations in washers and dryers. Notably, these extrusions must be able to perform with exposure to water, extreme heat and cold, and other hazards. Elbex's Expertise in Custom Appliance Extrusions At Elbex, our team takes a collaborative approach in creating custom appliance extrusions for your business. We draw on our deep knowledge of different rubber compounds to select materials that meet industry and regulatory standards. For example, while silicone is best for high heat/food contact, EPDM is better for weather/water resistance. Materials expertise is paired with an advanced extrusion process, which forces uncured rubber through custom dies to create precise, fully cured profiles. Rather than carrying an inventory, we custom-manufacture every product to meet your exact requirements, ensuring superior stability and performance. Versatile Appliance Applications & Custom Profiles Appliance gaskets (which are static surfaces) and seals (which are moving parts) fill many roles in the appliance industry. Formed hoses and water resistance seals in washing machines and dishwashers, air barrier seals in refrigerators and ovens, and even blender lid seals provide necessary containment for appliances. Gaskets and seals can also eliminate vibrations and secure components. Our custom profile options include extruded gaskets and seals, bulb seals, custom extruded rubber d-sections, and custom extruded ribbed profiles. Each of these options can aid with filling voids, creating seals/barriers, reducing vibration, and more. Elbex's Unwavering Support and Resources Working with Elbex means you get a team that is committed to the success of its customers. Our team is ready to assist right from the start, offering guidance on materials selection and design assistance (including additional technical resources) to ensure the design and finished components meet your performance requirements. By doing all custom tooling in-house, we can also deliver our results faster and cheaper than if the work was outsourced, even while maintaining extremely high quality standards.  With our extensive expertise in high-quality appliance rubber extrusions, including appliance gaskets and appliance seals, you can count on Elbex to help ensure that your appliances are reliable and compliant for your own customers.
