Silicone sealing plug

This sealing cap is essential for making your polycarbonate molds watertight. It is reusable and very easy to install, which will save you time compared to sealing paste.

• To use this sealing plug, simply pass your wick through the hole in your polycarbonate mold, with the end of the wick sticking out. Then, push your plug onto it (you can see the pictures above).
