Product Overview & Key Advantages
Our specialized T, U, and D-shaped rubber seal strips are engineered to provide reliable, long-lasting seals against environmental elements. Ideal for industrial, automotive, marine, and construction applications, these extruded profiles offer tailored solutions for gaps, edges, and channels where standard seals fall short. We combine advanced polymer compounds with precision manufacturing to deliver superior performance.
Optimized Seal Design: The distinct T, U, and D cross-sections are crafted to fit specific grooves and surfaces, ensuring maximum contact and sealing pressure for enhanced protection against dust, water, air, and noise.
Superior Material Selection: Available in EPDM (excellent weather/ozone resistance), Silicone (high-temperature), Neoprene (oil & flame resistant), and PVC, ensuring compatibility with your operating environment.
Exceptional Durability: Our compounds resist UV radiation, extreme temperatures (-60°C to 300°C range available), oxidation, and corrosion, guaranteeing a long service life and reducing replacement frequency.
Easy Installation & Flexibility: Designed for simple press-fit or adhesive-back installation into corresponding channels. The material flexibility allows for smooth application on curved or straight surfaces.
- Customization Ready: Beyond standard sizes, we specialize in custom extrusion. We can adjust dimensions, hardness (Shore A), color, and material to meet your exact OEM or project specifications.
Profile Shape | Key Dimensions (A x B x C)* | Standard Length | Available Materials | Hardness (Shore A) | Color |
|---|---|---|---|---|---|
| T-Shaped Seal | 6mm x 10mm x 3mm (Stem x Top x Leg) | 10m / 20m / 50m rolls | EPDM, Silicone, PVC | 50±5, 60±5, 70±5 | Black, White, Gray |
| U-Shaped Seal (Channel) | 10mm (H) x 5mm (W) x 2mm (Thickness) | 10m / 20m / 50m rolls | EPDM, Neoprene, PVC | 40±5, 50±5, 60±5 | Black, Custom |
| D-Shaped Seal (Bulb) | 8mm (Dia.) x 5mm (Base Width) | 10m / 20m / 50m rolls | EPDM, Silicone | 30±5, 40±5, 50±5 | Black, White |
Common Applications & Uses
T-Shaped: Perfect for insertion into T-slots in panels, machinery guards, and assembly lines. Commonly used in cabinet sealing, electronic enclosures, and automotive trim fixation.
U-Shaped/U-Channel: Ideal for wrapping and protecting the edges of glass, metal sheets, and automotive doors/windows. Provides a secure grip and cushioning.
D-Shaped/ bulb seals: Excellent for compressing against flat surfaces to create an airtight/watertight barrier. Widely used in refrigerator doors, industrial ovens, sealing hatches, and HVAC systems.
Proper Usage Guidelines
Surface Preparation: Ensure the mounting surface is clean, dry, and free of oil, dust, or old adhesive residue.
Measurement & Cutting: Measure the required length accurately. Use a sharp blade or scissors for a clean, straight cut.
Installation:
For T-strips, align and press firmly into the matching T-slot channel.
For U-channels, align over the edge and press evenly along its length.
For D-strips (often with adhesive backing), peel the liner and press the seal onto the surface, starting from one end.
Joining Ends: For continuous sealing, cut ends at a 45° angle and butt them together tightly. For critical seals, a compatible adhesive can be applied at the joint.
