Secure Seal Tester

The PRESTO Secure Seal Tester allows you to test thread and seal integrity on your glass or plastic carbonated beverage containers. The Secure Seal Tester has been designed to address the special needs of sealing carbonated beverages containers that use aluminum roll-on, twist crowns, or plastic caps. By detecting gas leakage, rather than liquid, the Secure Seal Tester gives more sensitive, accurate readings.
