Data scope & source
The main AS568 table contains 349 dash numbers across six cross-section groups: 001–003, 004–050, 102–178, 201–284, 309–395 and 425–475. The separate 900-series boss-gasket sizes are outside this site's main AS568 size finder.
SAE AS568F is the current AS568 revision and was reaffirmed January 29, 2026. SAE describes the standard as specifying inside diameters, cross-sections, tolerances and size identification codes.
