Conical silicone plug with hole (high elasticity); silicone tube cap seals the pipe opening
Silicone tube cap (also known as silicone end cap or silicone plug) mainly functions to seal pipe openings, provide shielding protection, or assist in surface treatment. It is used to cover pipe ends, threads, or irregular metal surfaces, utilizing the high-temperature resistance (-60~250℃) and chemical resistance of silicone to isolate electroplating solution, powder coating, or oxidizing agents and prevent these areas from being accidentally plated or coated. After the treatment is completed, it can be repeatedly disassembled without any residue left on the surface
