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: โข Assembly aid, depending on the installation type (in a bore, on a piston, cover fitting with internal or external pressure) โข Compounds compatibility with various fluids โข Intelligent O-Ring measuring tool with the smartphone's camera function โข 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.
