RL11 tapered corks are medium to large natural cork stoppers made from 100% sustainably harvested cork, designed to seal medium to large openings with a secure, reliable fit. The tapered profile is wider at the top, narrowing toward the base and allows a single stopper to accommodate a range of opening sizes, including containers with nonuniform openings where a straight-sided plug would fail to seal reliably. Natural cork compresses slightly on insertion, creating a snug seal without adhesives or tools, and its inherent flexibility means it conforms to minor variations in the opening. Whether referred to as end plugs, masking plugs, or hole fillers, these stoppers deliver dependable performance across every use. Each RL11 tapered cork measures 27mm at the top diameter, 21mm at the bottom diameter, and 31.8mm in length. Perfect for sealing glass and ceramic jars, bottles, medium to large containers, larger test tubes, laboratory vessels, construction holes, masking applications, craft projects, science applications, and any industrial or commercial use requiring a reliable, natural plug.
RL11 tapered corks outperform synthetic rubber and plastic plugs by combining natural compressibility with sustainable sourcing for a seal that's reliable, clean, and kind to the environment.
