It is correct to assume that as the hardness of the rubber increases so too does the compressive load. Parker’s O-Ring and Engineered Seals Division offers materials that cover a range of 40-95 durometers (Shore A scale). https://t.co/L3IZb14pHK

many metal components can add significant cost and lead time. For example, many die cast parts require machining operations to drill and tap threads while most thermoplastics can be molded with pre-formed holes and use thread forming screws. https://t.co/3uaKljLLst

A common myth in the sealing industry is that there is a correlation between material family and compressive load requirements, but as seen in the graphic below, that is not necessarily the case. The only truly accurate statement is that silicone https://t.co/L3IZb14pHK

2) The ASTM standard does not specifically list what actual chemicals the seal has to be compatible with as well as the operating conditions. ASTM tests compatibility based on Standardized Testing Fluids which are Oils, Fuels and Service Liquids. https://t.co/2jh6uMBS0f
