Jtube Jar Top ((install)) 【OFFICIAL × Workflow】

A: The Masontops Jar Safe lid is specifically designed to fit standard Regular Mouth (2.75" diameter) and Wide Mouth (3.38" diameter) Mason jars from brands like Ball, Kerr, and Bernardin. Cylindrical J-Tubes are standalone products with their own specific threaded caps and are not designed to fit onto a Mason jar.

The most recognizable feature of a plastic J-Tube is its continuous, integrated closure. By applying pressure to designated "squeeze points" near the top of the tube, the internal pressure causes the hinged cap to pop open with a distinct audible click. This single-piece construction prevents lost caps and streamlines the retail filling process. Common Size Formats jtube jar top
