An oring acts as a seal by blocking any potential leaching path, of a liquid or gas, between two closely matted surfaces An oring is installed in a machined grooved gland (see gland design for examples) in one of the two surfaces to be sealed As the two surfaces are brought together the orings cross section becomes deformed producing a tight seal, see image The greater theFastDash TM Oring Piston Seal Design Guide Enter the "A" diameter (ie bore diameter), Press the "Submit" button, The appropriate dash no orings will be listed along with their associated groove details BackUp Rings req'd None 1 2 "A" Diameter inches Oring CrossSection Selections103 in139 in210 in Dash No Act ID Dash No Act ID Dash No Act ID GrooveDesign Chart 7 shows the groove width necessary to accommodate the thickness of the backup rings Teflon backup rings are usually furnished in single or dual turn rings Single turn rings conform to MS and match the standard PAI Oring sire Dual turn rings conform to MS 287 and match the dash numbers of an AN 6227 series of Orings MS 287 backup rings
