Deformation of fittings and seals
Liquid drops under high pressure act like solid parts. Tightening connections
under high pressure can deform or destroy fittings and seals.
Never tighten flow connections under pressure.
The lifetime of a fitting depends on how firmly it has been tightened; firm
tightening reduces the lifetime.
If fitting has been overtightened, replace it.
