89-400 Natural-Colored Dome Cap (Foam Liner)

This 89-400 natural-colored dome cap is a dependable closure for extra-wide-mouth jars. The natural finish has a soft, semi-translucent look that suits clean, simple, or eco-minded branding, and the domed top gives a rounded silhouette that stands out from a standard flat cap. Each cap has a polyethylene foam liner that compresses against the container rim when tightened. This creates a reliable, leak-resistant seal that keeps contents fresh and helps prevent spills during shipping and storage. Features Size: 89mm diameter with a 400 neck finish Style: Dome top for a distinctive look Liner: Foam liner for a secure, leak-resistant seal Color: Natural (uncolored, semi-translucent) Compatibility: Fits glass and plastic containers with an 89-400 neck finish Ideal For Wide-mouth jars holding body butters, scrubs, creams, balms, gummies, candies, herbs, flower, spices, snacks, and other products that benefit from a tighter seal. A strong choice for cosmetics, food, cannabis, and home goods brands that want easy access to contents without sacrificing freshness. Tip: Always confirm your container’s neck finish before ordering, since an 89-400 cap will not properly fit other finishes. For oil-heavy or solvent-based products, test the liner with your formula first.
