In many industrial applications, from aerospace to construction to transportation, extruded rubber components are much more than simple trim. These profiles are critical sealing solutions, flexible tubing, and vibration-control parts that help systems operate reliably under stress. At NW Rubber Extruders, our extrusion capabilities produce seals, tubes, and complex profiles that meet demanding specifications and functional requirements.
The Role of Seals, Tubes & Profiles in Engineering
- Seals (Gaskets / Weatherstripping):
Our extruded seals can take countless cross-sectional shapes, from P-seals and J-channels to H-profiles and “E”-seals. These geometry options allow for very specific sealing behaviors, whether you need to exclude water, air, dust, or other contaminants. NW Rubber Extruders+2NW Rubber Extruders+2
- For instance, our E-shaped profiles include a hollow groove and compressible seal to interface with mating surfaces, offering reliable compression and sealing against moisture or debris. NW Rubber Extruders
- Our H-profiles are especially useful for window or panel seals, where two surfaces need a resilient, continuous contact. NW Rubber Extruders

- Tubes / Extruded Rubber Tubing:
Rubber tubing is a go-to for fluid transfer, protective sleeving, or cushioning applications. Our extrusion process supports a variety of materials and diameters, so you can get tubing that is chemically compatible, flexible, and durable for your operating conditions. NW Rubber Extruders - Custom Profiles:
Beyond standard shapes, we can do highly customized profiles, whether that’s for edge trim, bulb seals, or complex multi-chamber profiles. This customization ensures that the part not only seals or protects but also integrates seamlessly with your design. NW Rubber Extruders+1
Choosing the Right Material for Seals & Tubes
The performance of an extrusion often starts with material selection. We offer a broad range of elastomer compounds so you can tailor the extruded part to your needs:
- Chloroprene (Neoprene®): Excellent for weather resistance and moderate chemical exposure. NW Rubber Extruders
- EPDM: Great resistance to ozone, UV, and aging, ideal for outdoor seals. NW Rubber Extruders+1
- Natural Rubber: High resilience and tear resistance, suited for dynamic sealing. NW Rubber Extruders
- Nitrile (Buna N): Superb for oil- and fuel-resistant applications. NW Rubber Extruders
- SBR & Blends: For general-purpose extrusion when abrasion resistance or cost-effectiveness is important. NW Rubber Extruders
Precision & Size Capabilities
One of our strengths is precision: because we make our own extrusion tooling in-house, we maintain tight tolerances and profile accuracy. NW Rubber Extruders
We’re set up to run quite a range:
- Diameters from 1/16″ up to 14″ wide for extruded profiles. NW Rubber Extruders
- Lengths up to 20 feet in straight extrusion, or coiled lengths up to 200 feet, making us flexible for both prototyping and high-volume production. NW Rubber Extruders
Meeting Industry Specs & Standards
We know many of our customers work in regulated or highly specified industries. That’s why our extruded parts can be manufactured to meet:
- AMS
- ASTM D-2000
- MIL-specs
- FDA requirements (for food or medical applications) NW Rubber Extruders
On top of that, our quality control is strong and consistent, helping ensure that your seals and tubes perform reliably in critical uses.
Real-World Impact: Why These Extruded Elements Matter
- In automotive and commercial vehicle applications, extruded seals and bulb profiles help with weather stripping, noise control, and keeping out moisture.
- For construction, things like edge trim, glazing seals, and expansion-joint profiles prevent water ingress and absorb movement.
- In medical devices, tubing made from biocompatible elastomers is pivotal for fluid lines, small-bore connections, and sterilizable systems.
- Aerospace and military applications often rely on custom extruded gaskets that can handle temperature extremes, vibration, and strict specification requirements.
Final Thoughts
Extruded rubber seals, tubing, and custom profiles may seem like behind-the-scenes parts, but they often dictate the reliability, longevity, and effectiveness of an entire system. With our in-house tooling, material expertise, and precision manufacturing, we deliver extruded solutions that truly perform.
