The Product Testing Engineer at Dayco Inc. in USA, undertook the following testing with remarkable results:
Hoselink fittings were tested by connecting a hose to a tank that generated continuous cycles of water throughout the day, without interruption, for up to 480 cycles per day.
The tank runs cycles of both hot and cold water. Hot water ranged from 120 - 140 Degrees Fahrenheit, while cold water was generally anything less than 80 Degrees Fahrenheit.
One cycle of three minutes consists of the following flows of water:
30 seconds of flow through water at zero pressure (cold water)
1 minute at 100 PSI cold water
30 seconds of flow through water at zero pressure (hot water)
1 minute at 100 PSI hot water.
The three minute cycles continued without interruption for the full day equalling a total of 480 times per day.
To create a good comparison, the more conventional click-on style fittings were also subjected to the above testing.
