Rubber Plugs / Rubber Stoppers are functional rubber sealing and protection products. Custom rubber plugs can be developed according to drawings, samples, or working conditions, with support for different materials, hardness levels, sizes, and structural requirements. They are widely used for plugging and protecting pipe ends, holes, bottle openings, and ports against dust, water, and contamination, as well as for masking and protection during the processing of electronic, automotive, and hardware components. Customization is available for size, hardness, color, and compound formulation based on customer requirements. Typical applications include mechanical equipment hole protection, pipeline plugging, chemical container sealing, automotive component protection, electronics port sealing, and general industrial sealing.

FAQ
Q: Material options for rubber plugs?
A: Common: silicone (food-grade), NBR (oil-resistant), EPDM (weather-resistant), FKM (high-temp/corrosion). Choose as needed.
Q: Can rubber plugs of various apertures and shapes be customized?
A: We support customization of round, square, special-shaped and various aperture rubber plugs.
Q: Is the elastic plugging effect good?
A: High elasticity adapts to the aperture, tight insertion without loosening, good sealing and plugging effect.
