Pipe caps are important components in piping systems, primarily used to seal the ends of pipes. Based on material and application, pipe caps can be classified into plastic caps, metal caps, and rubber caps. Plastic caps are lightweight and corrosion-resistant, suitable for household or low-pressure environments; metal caps are high-strength and suitable for high-pressure or high-temperature applications; rubber caps, due to their good elasticity, are often used for temporary sealing or shock absorption.
