Square rubber seal strips are elastic components made from a variety of rubber materials, including silicone, EPDM (Ethylene Propylene Diene Monomer), and NBR (Nitrile Butadiene Rubber). Their square shape allows for easy installation and ensures a robust sealing capability in joints or openings of different profiles. These strips are commonly used in applications like automotive assemblies, construction, HVAC systems, and home appliances, providing protection against dust, moisture, and air leakage.
