North Mountain Supply 28mm White Plastic Screw Caps are designed to provide a reliable, leak resistant seal for a wide range of products. Each cap features a 28 400 continuous thread finish, making it compatible with most standard jars and bottles that use this common neck size and thread style.
These caps are molded from durable white plastic and include ribbed sides to make application and removal easier, even when hands are wet or slippery. The matte top offers a clean, professional look that pairs well with both glass and plastic containers in the kitchen, workshop, or production space.
Inside each cap is an F217 foam liner, a versatile, general purpose lining material that works with many types of products. F217 liners help create a dependable seal, reducing the chance of leaks or spills during storage, handling, and transport when used with properly matched containers.
The pack of 15 is a convenient quantity for small batch producers, hobbyists, and anyone who needs replacement caps for existing containers.
