How to Check Quality Control of Lug Cap?

  1. Cap seal – regularly check torque measurements as detailed.

    When exposed to shock, it will cause the cap to ring or come loose, leading to a loss of vacuum. 
  2. It has a tight seal and will leave a 360-degree impression of the glass rim in the cap sealing compound.

    A cross-threaded cap will lead to an uneven imprint, which will not result in a good seal.

    Using a pre-heated cap improves the compound impression and seal. 
  3. Visually inspect the depression in the cap’s center, which should be concave.

    When the seal is broken, a good vacuum pulls down the center of the cap.

    No vacuum will show up as convex in the cap’s center. If you use a cold fill, this is exactly what will happen. 
  4. Before packing, dry the jar, bottle, and cap, especially under the cap rim.

    It has an entrapped moisture between the cap and the glass rim that might cause corrosion.
