RL08 tapered corks are medium natural cork stoppers made from 100% sustainably harvested cork, designed to seal medium openings with a secure, reliable fit. The tapered profile — wider at the top, narrowing toward the base — 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 RL08 tapered cork measures 7/8in (22.2mm) at the top diameter, 43/64in (17.1mm) at the bottom diameter, and 1-1/16in (27.0mm) in length. Perfect for sealing glass and ceramic jars, medium containers, test tubes, laboratory vessels, construction holes, masking applications, craft projects, science applications, and any industrial or commercial use requiring a reliable, natural plug.

Why Choose RL08 Tapered Cork Stoppers?

• 100% natural cork construction provides a compressible, self-sealing fit without adhesives or hardware
• Tapered design fits a range of opening sizes — including nonuniform openings where straight-sided plugs won't seat correctly
• Naturally sustainable and biodegradable, making them the environmentally responsible choice over synthetic rubber or plastic plugs
• Suitable for food-contact, laboratory, and industrial environments where a clean, inert seal is required
• Available in bags of 80 for small-scale or craft use, or cartons of 4,000 for commercial and industrial volume
• Consistent sizing across the RL range makes it easy to step up or down to adjacent sizes as needed
  

RL08 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.
