Documentation is not paperwork for its own sake; on leak prevention it is the difference between a clean clearance and a delayed one.
Why leak prevention matters on the Nex Pro
Consistent filling torque and proper sealing rings remove most transit leaks.
Freight consolidation changes the answer to leak prevention at container scale, which is why small and large buyers reach different conclusions.
