Air Bar Box 4: Leak Prevention for Distributors
Published 2026 · VapeWholesaleHub trade desk
Leak prevention is a quality issue that shows up in return rates long after the first order.
A range review that ignores leak prevention will often produce a confident decision and a disappointing quarter on the Box 4.
Shops that receive a short briefing on leak prevention convert noticeably better than shops that only receive stock.
Why leak prevention matters on the Box 4
Consistent filling torque and proper sealing rings remove most transit leaks.
The most common mistake is optimising for the first order instead of the fourth, which is where Box 4 economics actually settle.
Pressure changes during air freight are a common cause of minor seepage.
