It also offers excellent resistance to ozone, sunlight, and weathering, making it ideal for outdoor and aerospace applications. Silicone is generally compatible with water, many alcohols, dilute acids, and certain oils, but is not recommended for use with concentrated acids, fuels, aromatic hydrocarbons, or steam under pressure.With a shore durometer of 70A, this silicone O-ring indicates a specific hardness level and its resistance to permanent indentation. A higher durometer value reflects greater resistance to indentation, with the scale ranging from 0 to 100, where 100 means no indentation occurs.O-rings are typically employed to create pressure and fluid seals between overlapping cylindrical surfaces. They are commonly found in applications such as food processing equi\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43357748461777,"sku":"BW-B0GVPW4DX6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/51vB3gSnY_L._SL1500_9ff0ab97-2623-4301-9a73-1f69a53ea1a6.jpg?v=1790985899","url":"https:\/\/belmontwarehouse.com\/products\/25-pk-as-210-silicone-o-ring-70a-3-4-id-1-od-1-8-width-red","provider":"Belmont Warehouse","version":"1.0","type":"link"}
