Cash flow is the quiet constraint behind leak prevention: the cheapest option is rarely the one that frees the most working capital.
Why leak prevention matters on the Royal 4
Consistent filling torque and proper sealing rings remove most transit leaks.
The most common mistake is optimising for the first order instead of the fourth, which is where Royal 4 economics actually settle.
Pressure changes during air freight are a common cause of minor seepage.
