FITS 12oz - 16oz (& WIDE-MOUTH 8oz) BOTTLES - Ensure a leak-free seal by checking your size. This Large adapter is designed for bottles with a 28-400 neck finish (typically 12oz, 16oz, and some Wide-Neck 8oz). Quick Check: Remove the cap. The threaded bottle neck should be noticeably wider than a US Quarter coin. Fits bottle openings with an Inner Diameter around 20.5mm - 22.4mm (0.81 inch - 0.88 inch).
SECURE NO-FALL FLANGE DESIGN - Engineered to solve the complaint of generic plugs falling into the bottle. Our adapter features an oversized 25mm Top Flange that sits securely on the rim of the bottle. Even with vigorous syringe insertion, this wide brim acts as a physical safety stop, preventing the adapter from ever being pushed inside your medication.
EXTRA-DEEP 13.8MM RETENTION SKIRT - Stop wasting expensive liquid prescriptions. Unlike shallow plugs, this adapter features a 13.8mm deep skirt with multiple friction fins. This extra depth provides superior stability, allowing you to confidently flip heavy bottles upside down to draw every last drop without the adapter popping out.
HIGH-FRICTION SEALING RINGS - The plug body is 20mm wide with flexible sealing ribs that expand to 23mm. These ribs compress against the bottle wall to create a high-friction seal that prevents leaks and spills during dosing.
HYGIENIC 25-PACK SUPPLY (BPA-FREE) - Made from medical-compliant, food-grade LDPE for safe contact with all liquid formulas. The 4.4mm center hole fits standard slip-tip oral syringes. Vital Safety Note: Always screw the original child-resistant cap (CRC) back over the adapter for storage. Warning: Choking Hazard, keep away from children.
