Stopflex helps to improve hydraulic systems safety, offering a solution to restrain pressure hoses, reducing the possibility that the whip effect takes place, as suggested by ISO 4413:2010 standard.
Stopflex components can be applied to all kinds of flexible hoses. A band, equipped with a rubber gasket, remains perfectly secured to the hose, simultaneously allowing it to swell according to the working pressure. The retaining components can be secured to nipples, SAE flanges or other system components.

The Stopflex system, upon correct assembly, was manufactured and tested to ensure the retention of the hose up to the maximum pressure indicated in this catalogue, in compliance with the following standards regulating the manufacturing of hydraulic flexible hoses:
EN853 - EN854 - EN855 - EN856 - EN857 - SAEJ517

The energy contained within a pressure hose, in case of disconnection from the fitting, can be very dangerous to anyone or anything in its vicinity. The Stopflex retention system was designed to arrest the trajectory of the flexible hose, thus avoiding that the energy contained inside triggers a dangerous “whip effect”.
