Black Plastic Cap Stopper, 19.5mm Synthetic Stem

Synthetic stem bar top stoppers with a ribbed black plastic cap are high-volume bottle closures made from a durable synthetic stem and rigid plastic cap, engineered for consistent, reliable sealing across automated bottling operations. The ribbed cap provides a secure, easy-grip surface for quick opening and resealing, while the synthetic stem delivers a firm, uniform fit that performs consistently across spirit types and proof levels. The smooth synthetic construction resists absorption and degradation, making it a dependable choice for high-output production environments. Cap diameter is 29mm with a 9mm cap height; stem diameter is 19.5mm with a 20mm exposed stem length, designed to fit bottles with an 18.5mm internal bore. Perfect for distilleries, spirit producers, olive oil bottlers, hot sauce manufacturers, vinegar producers, and any high-volume bottling operation seeking a consistent, economical closure solution.

Why Choose Synthetic Stem Bar Top Stoppers with Ribbed Black Plastic Cap?

• Synthetic stem is spirit-safe at all proof levels — no risk of taint or absorption that can affect natural cork closures
• Ribbed cap design ensures easy gripping and consistent torque on automated and manual lines alike
• Uniform synthetic construction delivers tight dimensional tolerances, reducing line stoppages and rejects
• Economical per-unit cost at carton volume makes it one of the most cost-effective closures for high-output bottling
• Compatible with most automated bottling lines, minimizing changeover and integration costs

Synthetic stem stoppers outperform natural cork bar tops in high-volume production settings by combining spirit-safe synthetic materials with rigid cap consistency ensuring reliable, repeatable performance across every bottle on the line.
