All of our stoppers are moulded. They are BPA-free, made out of Food Grade materials. They provide an air-tight seal to carboys, necessary for proper fermentation. They come with molded hole.
Each has a perfect consistency as they are all injection molded.
The quality is comparable to silicone stoppers. They stick perfectly to Glass and PET, even when they are wet, however, to improve the seal between glass carboys and the stoppers is best if both are dry.
BPA Free.
Maximum Temperature: 70 °C (158 °F).
NOTE: Our bungs can be recycled as they have the plastic recycling symbol #7 . This type of plastic is fully recyclable and environmentally friendly. Should you have any questions about the material and/or any environmentally-related questions please do not hesitate to contact us. We are committed to protecting the environment at any cost.
