Some applications require the hose to resist collapse in suction and vacuum service. Such hose is subjected to crushing forces because the atmospheric pressure outside the hose is greater than the internal pressure. The hose can collapse and restrict the flow unless the hose is constructed to resist these pressure differentials.
Vacuum testing is to ensure that any hose that is build for vacuum or suction purposes will perform efficiently and reliably in its intended application.
