Twist-n-Seal Stopper

This clever reusable plug forms a lasting, airtight seal on plastic nozzles or tubes from 3/32" to 7/16" internal diameter. Made of a tough plastic composite, it inserts simply by pushing and turning. The fine screw-like threads deform the softer nozzle or tube material, so it grips securely but removes easily by unscrewing.

Dried glue or caulking does not adhere to the non-stick plastic. Far better than using a screw or tape (or even the cap supplied with most adhesives!). Package of five.

Made in USA.
