30mm Blue Silicone Blanking Cap
Product description
Key features
This blue silicone blanking cap is a high temperature round sealing plug designed to block off hoses or openings with a 30mm internal diameter. It combines a gloss finish with a two‑layer VMQ silicone construction that handles a wide temperature range, making it useful for workshop or light industrial tasks where a reliable temporary seal is required. The plug is simple to fit and removes the need for specialist tools, so it works well for quick maintenance or testing jobs.

If you plan extended exposure to aggressive chemicals, bear in mind that silicone resists many substances but may not suit every solvent.
