4-1/2 ID 1/4 Width Round Pack of 5 70A Durometer 425 Buna-N O-Ring 5 OD Black
















425 Buna-N O-Ring,70A Durometer,Round,Black,4-1/2' ID,5' OD,1/4' Width,Pack of 5,: O Ring Seals: Industrial & Scientific,425 Buna-N O-Ring,70A Durometer,Round,Black,4-1/2" ID,5" OD,1/4" Width,Pack of 5,: O Ring Seals: Industrial & Scientific,This O-ring is made of black Buna-nitrile,is round in cross-section,has a durometer of 70A,and is designed for use in a wide variety of sealing applications,Buna-nitrile can have high tensile strength,and abrasion,tear,and compression set resistance,It can be used in temperatures between -30 degrees F,-34 degrees C,to 0 degrees F,11 degrees C,and is compatible for use with petroleum,HFA,HFB and HFC fluids,vegetable oil,alcohol,acids and aliphatic hydrocarbons,Buna-nitrile is vulnerable to acetone,ethers,esters,ozone,sunlight and weathering and should therefore not be used in ozone-generating electric motors,welding equipment,or in applications with exposure to UV light,This Buna O-ring has a shore durometer of 70A,Shore durometer is the hardness of a material,and its resistance to permanent indentation,A higher durometer value indicates greater resistance to indentation on a scale of 0 to 100,with 100 indicating no indentation,O-rings commonly provide a pressure and fluid seal between cylindrically shaped,overlapping mating surfaces and are commonly seen in engines,faucets,flanges,valves,and various cylinders,They are circular in shape,with a round cross section,and a hole in the center,similar to a doughnut,O-rings are available in various sizes,and can be ordered based on required nominal inside diameter,ID,outer diameter,OD,and cross-sectional,CS,diameter,These Buna-nitrile O-rings meet standards defined by Aerospace Standard AS68A,which is the Aerospace Size Standard for O-rings
