CFDPLAS Flat silicone ring gaskets provide a soft,flexible,and heat-resistant seal for bottle caps,plumbing connections,and industrial closures.
Key Features & Benefits:
Material Properties: Made from medical- or food-grade silicone, these gaskets resist aging,ozone,and wide temperature extremes (typically ranging from -40℃ to 230℃ or higher depending on the grade).
Leak Prevention: The flat profile distributes compression evenly across mating surfaces,filling micro-gaps on plastic,glass,or metal closure lips.
Vibration and Cushioning: Soft silicone acts as an effective dampener against mechanical vibrations and prevents metal-on-metal or glass-on-plastic wear.
