Custom Rubber Gasket Design



Our design experts will assist you in selecting the appropriate material for your gasket applications. They base their recommendations on your needs and specifications to accommodate the appropriate temperature, chemical, vibration, abrasion and movement requirements for your application.

We offer the following rubber & gasket materials:


Natural Rubber (NR) can have many different names, Isoprene, Polyisoprene, but is most commonly known as Gum Rubber. Using NR has many advantages such as high tensile strength, superior resistance to tearing and abrasion, and excellent rebound elasticity. Natural Rubber has the most flexibility at low temperatures, it has less resistance to heat, ozone, and sunlight. NR has exceptional adhesion quality to fabrics and metals but does have very little resistance to oils, gasoline and hydrocarbon solvents. Natural Rubber is a great option for sealing product applications.

BUNA-N (Nitrile)

Here at Denver Rubber Company, we carry Nitrile materials that provide flexible solutions for a variety of fabrication projects. We have an extensive stock of Nitrile materials that can be used for your next application.

Nitrile, also known as Buna-N, acrylonitrile butadiene rubber, or NBR, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Although its physical and chemical properties vary depending on the polymer’s composition of nitrile, this form of synthetic rubber is useful because it is generally resistant to oil, fuel, aliphatic hydrocarbons, and other chemicals. NBR is typically used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, gaskets, and grommets. Nitrile’s ability to tolerate a range of temperatures from 40° to 226 °F making it an ideal material for applications requiring a wide range of temperatures. Nitrile, like natural rubber, can be attacked by ozone, ketones, esters, and aldehydes. Nitrile makes for an excellent sealing application.


Polyurethane products often are called “urethanes”,  they are an extremely diverse product due to the multiple ways it can be configured during manufacturing. This material can be used in the manufacturing of flexible, high-resilience foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires (such as roller coaster, escalator and skateboard wheels), automotive suspension bushings, high-performance adhesives, surface coatings, surface sealants, and hoses. Polyurethane materials are a great choice when thinking of your next sealing product application.


Silicone rubber (Q) is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in many different industries, and there are multiple formulations of it. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from -80°F to +550°F while still maintaining its appropriate properties. With the properties Silicone is composed of, its ease of manufacturing and shaping, silicone rubber can be found in a wide variety of products that can be used for various applications.


Hypalon Rubber is high grade and typically used as a rubber strip. This rubber has excellent adhesion to different metals while being weather and chemical resistant. Hypalon rubber is a very smooth material allowing it to lay correctly on different applications.


Skirt Rubber is most widely known to be used on conveyer belt systems preventing unwanted materials from falling down. This material helps block dust and other spillages from coming onto certain surfaces. This material can be used in a variety of industries because of the different benefits it offers. Some of these benefits include flexibility, wear resistant, and excellent sealing properties.
