The most effective security system for high pressure hoses retention.


Internationally patented system according to ISO 4413 hydraulic transmissions.

Stopflex is the result of extensive testing and years of application to all types of flexible hoses. The system maintains the trajectory of the hose in the event of disconnection of the fittings, avoiding the dangerous 'whip effect' caused by the explosive energy released.

Flexibility of Use

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.

Tested protection

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

Safety Guarantee

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”.
