Finally, there is our commitment to quality. We use rigorous testing and adhere to industry standards to ensure long-lasting, reliable performance for every project.


Applications Across Industries

Elbex’s expansion joints are used in many applications across a wide range of industries. For example, they are often used to protect piping systems from damage from thermal expansion, vibrations, and seismic activity. Expansion joints can also ensure flexibility and prevent stress in HVAC ductwork, piping, and equipment.


Expansion joints are especially vital in bridges, buildings, and other structures, where they help accommodate movement and prevent cracking. With additional applications in marine, power generation, and manufacturing, rubber expansion joints are truly versatile.


Types of Rubber Expansion Joints

Elbex produces several types of rubber expansion joints, including single arch joints that accommodate axial movement and multiple arch designs that provide greater flexibility for multi-directional movement. Both flanged and unflanged expansion joints are available.


Most importantly, our ability to create unique expansion joint designs enables us to meet specific project needs where standard designs won’t be sufficient. No matter what type of expansion joint you need, Elbex can help bring it to life.



With high-level engineering support, technical expertise, and dedication to customer satisfaction, you can count on Elbex to deliver top-quality rubber expansion joints for any application.

When you’re waiting on rubber extrusions, few things can become more frustrating than project delays caused by external vendors. Working with a manufacturer that relies on external vendors is rarely effective — which is why at Elbex, in-house tooling for custom rubber extrusions is our secret weapon. By providing custom tooling solutions for rubber profiles entirely in-house, we can deliver the results you need in a faster and more efficient way. Here’s how this approach makes a difference. From Sketch to Steel Our process starts with die design. The die is the blueprint that is used to manufacture the final part. With in-house die design, our engineers and toolmakers work together in the same building, preventing miscommunications, delays, and other potential issues. This also gives us total control over the quality of the steel and the precision of the cut used in die design. We can move forward with manufacturing knowing that everything will be done properly. Speed and Cost Savings for You By handling our rubber extrusion tooling services in-house, we’re able to produce a die in days, rather than weeks. That makes a huge difference for your project lead time compared to companies that outsource! Keeping everything in-house also lowers our own overhead for materials, transportation, and labor. We’re then able to pass these savings on to you so you can make better use of your manufacturing budget. Solving Complex Problems with Custom Tooling Most importantly, doing everything in-house allows us to develop custom tooling solutions for rubber profiles, even with difficult projects. In-house tooling allows us to troubleshoot difficult designs and create complex shapes that generic outsourced dies can't handle. By tuning our dies to the specific materials that will be used for your project, we can ensure a perfect product run every time. You can have confidence that everything will be done right the first time. By working with Elbex, you enjoy a streamlined, expert-led path that takes you from your initial concept to finished custom rubber extrusion in a way that fits your schedule.

“Bumps and bruises" are inevitable in busy industrial environments. But whether these incidents cause major damage to equipment and infrastructure often depends on whether or not you use extruded rubber bumpers. Impact-resistant rubber bumpers for manufacturing facilities provide a high level of protection against collisions, ensuring that such incidents don’t lead to even bigger problems. With custom rubber bumpers from Elbex, you can have even greater confidence that your equipment, vehicles, and infrastructure are properly protected. The Versatility of Extruded Protection Not all rubber bumpers are created equal. At Elbex, we use the rubber extrusion process, which allows us to produce rubber bumpers in long, continuous lengths. The curing that rubber components go through during rubber extrusion provides superior linear strength and durability when compared to molded alternatives, especially for lengthy bumpers. This process allows us to produce rubber bumpers for a wide range of applications. We can produce bumpers for loading dock protection in mass transit, or to protect docks and boat hulls in the marine industry. We can even produce custom bumpers to protect expensive machinery from forklift or trolley impacts. Designed to Take the Hit For industrial rubber bumpers, few things are more important than the right material. That’s why we use EPDM as our material of choice for these applications. EPDM’s strong abrasion resistance helps it withstand the wear and tear of harsh industrial environments. In addition, these impact resistant rubber bumpers for manufacturing absorb the energy of collisions. This helps them reduce vibration and structural stress on the equipment that is being protected, in addition to preventing surface-level scratches. Custom Profiles for Specific Risks The combination of the rubber extrusion process and our team’s industry expertise enables us to create heavy duty rubber bumpers for industrial equipment in a wide range of shapes and lengths. Whether you need D-sections, U-channels, or something else entirely, we’ll help you get the right fit. And with our salt-bath curing process, you can expect continuous quality and durability from end to end. A small investment in high-quality bumpers can help you save thousands in repairs to industrial structures and equipment. With Elbex, you’ll get the customized level of protection your facility needs. Contact us today to learn more about our capabilities or to request a quote for your facility.

From the dishwasher to the refrigerator, we rely on our home appliances every day. For manufacturers, providing the consistent performance your customers want often depends on a small component — appliance rubber seals. Quality rubber gaskets for appliances can make all the difference between a high-end machine and one that fails. With silicone rubber extrusions for appliance applications from Elbex, you can achieve the level of quality your products need. Why Precision Matters in Your Kitchen and Laundry Room Appliance rubber seals are vital for containing air, heat, and water in the kitchen and laundry room. This common need is shared by refrigerators, ovens, dishwashers, and laundry machines. Without proper containment, temperature and water leaks can spoil food or cause damaging water spills. Quality seals go beyond leak prevention by improving overall energy efficiency and reducing noise by dampening vibrations. This improved performance goes a long way in keeping customers happy with your products. Material Science for Modern Appliances At Elbex, we understand how appliances experience heavy use and harsh operating conditions that can damage low-quality seals. Because of this, we manufacture high temperature rubber seals for appliances like ovens and dryers to prevent degradation. We use silicone rubber extrusions for appliance applications because they offer the perfect combination of flexibility, food-safe properties, and durability across extreme temperature swings. With the right materials, you can have confidence that appliance seals will stand the test of time. Elbex’s Collaborative Design Process At Elbex, we believe in working as your engineering partners. Instead of just taking orders, we collaborate with your team to select the right materials and profiles based on your appliance design. This enables us to create appliance door seals and gaskets that will always achieve a perfect fit, even for appliances with unique specifications. After all, reliable appliances start with reliable seals. With high-quality silicone seals from Elbex, you can deliver the level of quality your customers deserve.
