The LD-375 rubber and PVC door bottom seal, sweep, and weatherstrip series provides an essential sealing solution for preventing drafts, dust, insects, sound, and moisture from passing through the gap beneath doors. Manufactured from high-quality EPDM rubber, PVC, and silicone rubber compounds, these profiles offer excellent compression recovery, UV resistance, and long-term flexibility across a wide temperature range. The seals are designed to fit door gaps ranging from 2mm to 15mm, making them suitable for virtually any residential, commercial, or industrial door where a tight perimeter seal is desired. Each seal features a rigid aluminum or steel carrier measuring 830-950mm that provides structural support and a clean mounting surface, while the flexible sealing element extends below to contact the threshold or floor surface.

The LD-375 line encompasses four primary profile types to address different gap geometries and sealing requirements. P-type profiles feature a tubular cross-section ideal for uniform gap sealing and moderate compression. D-type profiles offer a semi-circular shape that provides excellent conformability to uneven surfaces. E-type profiles use a dual-flap design for enhanced sound insulation and air barrier performance. Brush sweep profiles incorporate dense nylon filaments that effectively block dust and insects while allowing smooth door operation over carpeted or uneven floors. All profiles can be easily cut to the desired length within the 80-100cm range using standard hand tools, and the aluminum carrier includes pre-drilled or adhesive backing options for quick surface-mounted installation without specialized equipment.

Color flexibility ensures seamless integration with any door or interior design. The standard palette includes Black, Brown, White, Gray, and Clear, covering the most common door frame and threshold finishes. The EPDM and silicone compounds maintain their color and elasticity over years of exposure to sunlight, temperature cycling, and mechanical wear, outperforming cheaper PVC-only alternatives that can become brittle and crack over time. The RoHS compliance certification confirms that all materials are free from hazardous substances, making these seals safe for use in homes, schools, healthcare facilities, and food-processing environments.

As a wholesale supplier, we offer the LD-375 at highly competitive prices from $0.30 to $3.00 per piece depending on profile type, material, carrier specification, and order volume. The minimum order quantity is 500 pieces, with mixed orders across related SKUs fully supported to help distributors and contractors consolidate shipments and reduce logistics costs. Each piece is packaged in an individual polybag or color box, with 50-200 pieces per carton for efficient handling and storage. Samples are available for evaluation, and our standard production lead time of 10-20 days makes this one of our fastest-turnaround product lines for time-sensitive renovation and construction projects.
