Description

The Black Polyseal Screw Caps – 38mm are designed for use with gallon glass jugs and wide-mouth bottles that accept a 38mm screw cap. These caps feature an integrated polyseal liner, which compresses inside the neck of the bottle to create a tight, leak-resistant seal.

Polyseal caps are ideal for short-term storage of wine, cider, juice, kombucha, and other non-carbonated beverages. They are easy to apply by hand, require no special equipment, and provide a reliable alternative to corks for gallon jugs and fermentation jars.

The durable black polypropylene cap offers a clean, professional look while delivering dependable sealing performance for everyday use.

Note: These caps are intended for standard 38mm threaded gallon jugs and are not suitable for carbonated beverages or long-term aging.

Sold in packs of 5.
