Every serious sourcing conversation about the Smooth Plus eventually arrives at leak prevention, usually because it is where cost and risk meet.
Retail staff rarely ask about leak prevention directly, but their questions almost always lead back to it.
Why leak prevention matters on the Smooth Plus
Consistent filling torque and proper sealing rings remove most transit leaks.

Commercial terms
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

| Carton (154 units) | Tier 1 | 14-21 days |
| Pallet (1191 units) | Tier 2 | 7-12 days |
