Co-Extruded Sealing Gaskets without Carrier have different areas of hardness as measured on the Shore A scale. The harder rubber attaches to a substrate and provides impact resistance. The softer rubber compresses to fill a gap and provides sealing. Water jet equipment can be used to cut dual durometer rubber to length, and the finished gasket can be installed over a flange or attached with fasteners or adhesive tape.
Applications for Co-Extruded Sealing Gaskets without Carrier include door and window seals. For example, a dual durometer window seal can have a harder rubber section that attaches to a window frame and a softer rubber section that faces the window glass. With door seals, the harder section attaches to the door frame and the softer section fills the gap between the frame and closed door.
We provide coils, cut lengths, and finished gaskets made from dual durometer rubber.

How are Co-Extruded Sealing Gaskets without Carrier made?
They are co-extruded. During this manufacturing process, two (or more) materials are pressed together and pushed through the same die to produce a single product. Standard co-extrusions are typically faster to produce since they use an existing die. Custom co-extrusions have longer lead times since there is special tooling to design, machine, pay for, and wait for.
How hard or soft can the rubber get?
Rubber can be as soft as a pencil eraser or as hard as a hockey puck. Softer rubber has a lower durometer, and harder rubber has a higher durometer. Remember, however, that that softness or hardness of rubber can vary by temperature. If you leave a pencil in your car on hot July day, the eraser becomes even softer. If you put a hockey puck in a freezer, it becomes even harder.
Do Co-Extruded Sealing Gaskets without Carrier contain different types of rubber?
Yes, in the sense that most dual durometer products contain both sponge rubber and solid rubber. Sponge rubber has a cellular structure and is usually softer. Solid rubber does not have a cellular structure and is usually harder. Remember, however, that durometer – and not whether rubber is solid or sponge – is the measure of hardness.
