Custom Silicone Plugs (Stoppers)

Custom silicone stoppers and rubber sealing plugs to protect electronics and pipes

img sc silicone plug stoppers

Prevent fluid leaks and dust ingress with our silicone stoppers. Manufactured from high-quality silicone rubber, our elastic sealing plugs withstand temperature variations and resist environmental factors. Typical hardness ranges from 30 to 80 Shore A, with temperature tolerance from -40°C to 230°C, ensuring reliable performance in electronics, piping, and container sealing. The plugs prevent fluid leakage and dust ingress, ideal for instrument ports or temporary pipe closures. Custom sizes and shapes are available to meet specific OEM requirements. Quality assurance includes ISO 9001 certification and compliance with FDA, RoHS, and REACH standards, ensuring safe and consistent product quality.

Use cases:

  • Aperture sealing plugs and fluid leak stoppers used in electronics, piping, and containers as a seal or stopper to prevent fluid leakage and dust ingress (e.g., instrument ports or temporary pipe closures).
