Engineered with thickened, flexible TPE material and strong self-adhesive backing, this D-shape sealing strip is your go-to solution for blocking drafts, minimizing energy loss, and reducing irritating sounds in both home and commercial settings.

Whether you're sealing doors, windows, or even automotive and industrial equipment, this versatile strip brings enhanced insulation and peace of mind—quietly and effortlessly.

Product Description:

This weatherproof sealing strip is made from high-quality TPE rubber, known for its elasticity, resilience, and resistance to deformation. With a universal size of 800cm (L) x 10mm (W) x 6mm (T), it effectively seals gaps ranging from 2.5mm to 6mm.

The D-shaped profile enhances sealing efficiency by tightly compressing into door or window gaps. It comes with a premium adhesive layer that bonds securely to most surfaces—including wood, metal, and plastic—without residue or peeling. Plus, it’s easily cuttable and flexible, so you can shape it to fit around corners or curves.

How to Use:

Measure the gap between the door/window and the frame (use a ruler, coin, or folded paper method).

Cut the weather strip to the required length using scissors.

Clean and dry the application surface thoroughly.

Peel off the red adhesive film.

Press the strip firmly into the groove or along the edge.

Wait 24 hours after installation for full adhesive strength.

💡 Tip: In cold temperatures, use a hair dryer to warm the adhesive before applying for better bonding.

Notes & Precautions:

Surface Preparation: Ensure the installation area is clean, dry, and free of dust or old adhesive.

Temperature Sensitivity: Best installed in environments between 10°C–30°C. In colder settings, gently heat the adhesive strip before installation.

Adhesion Time: Avoid moving or pressing the strip excessively during the first 24 hours to allow full adhesive bonding.

Gap Compatibility: This D-strip works best for gaps between 2.5mm and 6mm. Please measure before purchase to avoid mismatch.
