Who hasn't sometimes wished for assistance when it comes to define the mounting dimensions for O-Rings or even find the right O-Ring? The Hutchinson O-Ring app offers precious tools: โ€ข Assembly aid, depending on the installation type (in a bore, on a piston, cover fitting with internal or external pressure) โ€ข Compounds compatibility with various fluids โ€ข Intelligent O-Ring measuring tool with the smartphone's camera function โ€ข Dimensions list for standard parts You can choose a reference number from thousands of available O-Rings and then precisely define the groove dimensions to ensure perfect sealing. On the contrary, after choosing the installation type and the groove dimensions, the app will recommend a list of compatible O-Ring dimensions. A smart measuring tool has been developed to measure your O-Rings dimensions. This can for instance be used in MRO for easy replacement. Take a coin to set the standard and watch your smartphone turn into a digital measure tool for precision seals! If chemistry classes are bad memories for you, the compound compatibility tool will help you to define the appropriate compound family, depending on the fluid used in your application.
