Rectangular Extruded Seals

Rectangular extruded seals are versatile sealing profiles offered in solid, hollow, or foam rubber variants that can be easily cut to length for custom applications. They are valued for their effectiveness in sealing flat surfaces and providing cushioning, vibration dampening, and edge protection in various industrial, automotive, and construction environments.
Key Features and Benefits
Effective Sealing: Rectangular seals are ideal for gap filling, weatherstripping (sealing doors and windows from environmental conditions), and preventing the ingress of dust, water, wind, and noise.
Versatility in Design: Available in solid rubber for durability and load bearing (acting as a bumper) or closed-cell sponge/foam rubber for enhanced compression and air/water sealing with minimal force.
Cushioning and Protection: The rubber material absorbs vibrations and cushions impact, protecting machinery components from wear and noise pollution.
Customizable: Extruded to order, these seals can be made in various sizes, colors, and materials and can include features like rounded edges or adhesive backing for easy installation.
Durable and Resilient: Designed to withstand harsh environments, including extreme temperatures, UV exposure, and chemicals, ensuring long-lasting performance.
Common Materials
The choice of material determines the seal's performance in specific operating environments:
EPDM (Ethylene Propylene Diene Monomer): The most frequent choice for outdoor applications due to excellent resistance to ozone, UV radiation, sunlight aging, and water absorption.
Nitrile (NBR / Buna-N): An excellent choice when oil and fuel resistance are the primary concerns, used in industrial equipment and fuel systems.
Silicone Rubber: Offers superior performance in extreme high and low temperatures and good chemical resistance. Specific grades are often FDA-compliant for medical and food industry use.
Chloroprene (Neoprene® / CR): Provides a balanced resistance profile, including good water, flame, and moderate oil resistance, often used in marine and HVAC applications.
PVC (Polyvinyl Chloride): A durable and cost-effective option for general-purpose edge protection and decorative trim.
Applications
Rectangular extruded seals are used across diverse industries for sealing and protection:
Automotive and Marine: Used as door, window, and hatch seals in cars, trucks, RVs, and boats.
Construction and Building: Applied in windows and doors for weatherproofing, insulation, and noise control.
Industrial Equipment: Employed in machinery access panels, electrical enclosures, and equipment guards to protect sensitive components from environmental elements.
Appliances and Electronics: Used as gaskets in domestic appliances and electronic devices to prevent dust and moisture ingress.
