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.

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

  1. Surface Preparation: Ensure the mounting surface is clean, dry, and free of oil, dust, or old adhesive residue.

  2. Measurement & Cutting: Measure the required length accurately. Use a sharp blade or scissors for a clean, straight cut.

  3. 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.

  4. 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.

Frequently Asked Questions (FAQ)

What is the best material for outdoor use in all weather conditions?

EPDM rubber is generally the best choice for outdoor applications due to its outstanding resistance to sunlight (UV), ozone, and a wide temperature range.

Can I get these seals with an adhesive backing?

Yes. Most of our profiles can be supplied with a high-performance pressure-sensitive adhesive (PSA) backing, protected by an easy-release liner for convenient installation.

Do you offer custom colors and minimum order quantities (MOQ)?

We do offer color customization for larger orders. Our standard MOQ for custom profiles is typically 500 meters, but we can accommodate smaller trial orders for established projects.

Do you offer custom lengths or specialized fittings?

Yes, we provide custom cutting and fitting services for wholesale orders of 500ft or more. Contact our hose and rubber supply team for custom quotations.

How do I choose the right hardness (Shore A)?

Softer seals (lower Shore A) provide better compression and conformability on uneven surfaces. Harder seals offer more structural rigidity and wear resistance. Our team can advise based on your specific application.

What are your lead times for samples and bulk orders?

Sample lead time is typically 5-7 days. Production lead time for bulk orders depends on the specification and quantity, usually ranging from 2-4 weeks. We prioritize clear communication on timelines.
