Molded & Extruded Seals

Molded seals and extruded seals include plugs, gaskets and other components used by a wide range of industries including automotive, medical, industrial, aerospace, construction and more. Rubber seals are easily customized and can be manufactured using various materials and processes to meet the design requirements of virtually any application.

Material Selection for Custom Rubber Seals

If you need a flexible seal for just about any machine, device, or product, look no further than Northwest Rubber Extruders. We use your custom seal design to create rubber seals using compression, injection and transfer molding, as well as specialty molding processes to meet your requirements.

We offer custom and standard rubber seals that will match your custom seal design, using a variety of flexible rubber, silicone, and thermoplastic materials, including:

  • EPDM: a synthetic rubber elastomer that is resistant to heat and weather and commonly used for door and window seals for automotive applications. 
  • Nitrile: a synthetic rubber copolymer that provides resistance to oil, fuel and chemicals and is commonly used for automotive and aerospace applications.
  • Neoprene: synthetic rubbers offering good chemical stability and maintains flexible in a wide range of temperatures. Commonly used for electrical insulation and automotive belts.
  • SBR: a family of hard synthetic rubbers that remain stable with aging and provide good abrasion resistance. Commonly used for gaskets and is a popular replacement for natural rubber.  
  • Silicone: an elastomer that is highly stable and suitable for extreme temperature applications. It is a versatile material used for applications ranging from medical devices to automotive seals.
  • TPV: a recyclable thermoplastic elastomer that is lightweight and provides dimensional stability and long-term aging durability. Common applications include automotive, construction, household and electrical.
  • PVC: a synthetic flexible plastic polymer that is often combined with stabilizers to create superior properties. Provides good insulation properties and is resistant to chemicals including salt, acids, alcohols and other corrosive substances. 
  • and many others

Our Elastomeric Material Selection Guide provides additional information regarding each material type including advantages, disadvantages and best applications.

Extruded Seals & Molded Seals Based On Your Custom Seal Design

At Northwest Rubber Extruders, we offer standard and custom rubber seals via extrusion and molding processes. We will determine which method is best for your project based on your material needs and application requirements. In some cases, molded and extruded seals can be combined into a single custom seal.

Our seal manufacturing process is fairly straightforward for molded and extruded seals: Simply provide us with your custom seal design and material specification, and we will create a die or mold to produce your desired product. We will then extrude or mold the rubber seals you need in the quantities you require.

No matter how simple or complex your custom seal designs, we will deliver precision products that meet or exceed your expectations. We use premium materials and proven extrusion and molding processes to ensure superior quality and durability. We are ISO 9001, AS 9100, and ISO/TS 16949 registered for quality assurance.
