In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Flux 4.

Why leak prevention matters on the Flux 4

Consistent filling torque and proper sealing rings remove most transit leaks.

A written internal standard for leak prevention makes onboarding new account managers far quicker and reduces avoidable errors.
