Why leak prevention matters on the Box 4
Consistent filling torque and proper sealing rings remove most transit leaks.
Shops that receive a short briefing on leak prevention convert noticeably better than shops that only receive stock.

Practical notes for buyers
Seasonality interacts with leak prevention more than most forecasts allow for, so a rolling review beats an annual one.
