T-Shape Extruded Seals

T-shape extruded seals are versatile sealing profiles with a characteristic "T" cross-section, commonly used for weatherstripping, gap sealing, and covering panel gaps in various industrial, architectural, and automotive applications. The wide flange and center bulb design provide flexibility and a secure fit for different mounting needs.
Key Features and Benefits
Effective Gap Sealing: The T-shape design creates a tight, continuous seal that is ideal for filling expansion joints or gaps between two parallel surfaces, effectively blocking out air, dust, water, and noise.
Aesthetic Finishing: Often used to cover seams or joints between panels, providing a clean, professional appearance while simultaneously offering a protective seal.
Versatility in Mounting: Can be designed for press-fit installation into a groove, or used with an adhesive backing for surface mounting, offering installation flexibility.
Durable and Resilient: Made from elastomers that are resistant to compression set, these seals maintain their shape and sealing effectiveness over a long service life, even with repeated use.
Vibration and Noise Reduction: The material and shape help absorb vibrations and sound, contributing to quieter operations in machinery and vehicles.
Common Materials
Material selection depends heavily on the operating environment and required resistances:
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.
Silicone Rubber: Offers superior performance in extreme high and low temperatures and good chemical resistance. Often used in food and medical applications where hygiene standards are high.
Nitrile (NBR / Buna-N): An excellent choice when oil and fuel resistance are the primary concerns, used in industrial equipment and fuel systems.
PVC (Polyvinyl Chloride): A durable and cost-effective option for general-purpose trim and edge protection where high flexibility is needed.
Applications
T-shape extruded seals are widely used across diverse industries for sealing, protection, and finishing:
Automotive and Marine: Used as seals for sunroofs, windows, doors, and panel gaps to reduce noise and prevent water ingress.
Construction and Building: Applied in architectural expansion joints and around door and window frames for weatherproofing and insulation.
Industrial Equipment: Employed in machinery access panels and enclosures to seal gaps and protect sensitive components from environmental elements.
Furniture and Display Cases: Used as trim for glass panels in display cases or cabinet doors to protect edges and seal against dust.
