Buyers who treat leak prevention as a commercial discipline rather than an afterthought tend to hold margin for longer.
Consistency across batches matters more than peak performance for Zen Ultra, and leak prevention is where inconsistency first appears.
Why leak prevention matters on the Zen Ultra
Consistent filling torque and proper sealing rings remove most transit leaks.
Documentation is not paperwork for its own sake; on leak prevention it is the difference between a clean clearance and a delayed one.

Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
