Studio, https://xemstudio.com/objects/backup-rings-as568-parker-8-xxx/ (sheet CC BY 4.0)\nBasis: Parker O-Ring Division's Parbak 8-xxx table (ID per size, series header values for width and thickness), cross-checked against McMaster-Carr's printed backup-ring table (190 sizes); 344 uncut ring envelopes as files\nCatalog version: 2026-10-20\n\nSizes: see table below\n- Parker's 8-xxx table lists 346 sizes in five series (8-004 to 8-050, 8-102 to 8-178, 8-201 to 8-284, 8-309 to 8-395, 8-425 to 8-475), each 'designed to correspond with the Parker 2-xxx, 3-xxx and AS568B series O-ring with which they are used'. The dash number is the O-ring's: 8-214 goes beside a -214 O-ring. Note that the series 8-0xx starts at 004 (no 8-001 to 8-003) and 8-1xx at 102.\n- Columns: ID is Parker's printed inside diameter in inches. W (radial width) is .053 / .086 / .118 / .183 / .236 in for series 0xx / 1xx / 2xx / 3xx / 4xx and T (thickness, Parker's 'Ref.' value) is .049 / .053 / .050 / .076 / .117 in; both are the values Parker prints above each series and McMaster-Carr prints the same width group and 'Thk.' for every series it sells. OD = ID + 2 x W: McMaster's printed OD equals that for every size it lists except 8-223. Millimetres are the inch values x 25.4 rounded to 0.01 mm. Parker's header also carries other numbers and tolerances whose letters the page text does not define; they are not used here.\n- Cross-check: McMaster-Carr prints ID and OD for 190 of the sizes (8-004 to 8-031, 8-042, 8-103 to 8-155, 8-158, 8-202 to 8-265, 8-320 to 8-351, 8-358 and 11 of the 4xx sizes); the IDs equal Parker's for every one except 8-344 (Parker 3.989, McMaster 3.898, both shown, no file) and the OD for 8-223 differs (McMaster prints OD 1.833 for 8-223; ID + 2 x 0.118 = 1.883 and every other McMaster row fits that rule, so 1.833 reads as a misprint on one side; both shown).\n- 8-176: Parker prints 9.238; the sizes either side are 9.018 (8-175) and 9.518 (8-177), step 0.25 would be 9.268, and no second source lists it, so the value is left out. Nothing was substituted.\n- Not covered: MS28774 (PTFE spiral / scarf-cut back-up rings) and AS5781 are searched under those names but no dimension table with numbers was readable, so none of their sizes or gaps are listed; do not assume they equal Parker's rubber Parbak numbers. Material, durometer and split style are not given in the Parker page text read.\n- Files: uncut rectangular ring envelopes at ID, OD = ID + 2W and thickness T. A molded Parbak has a contoured (concave) face and a PTFE ring is split; neither profile is published as numbers in the sources read, so the file is the space the ring occupies, not its exact face. Both disputed sizes (8-176, 8-344) have no file. The AS568 O-ring of the same dash is on as568-o-rings; groove widths that allow for one or two backup rings are on oring-gland-static-radial-as568 and oring-gland-dynamic-reciprocating-as568. McMaster-Carr sells backup rings with per-part STEP; its page is linked, not copied.\n\ndash ID (in) OD (in) = ID + 2W radial width W (in) thickness T (in) ID (mm) OD (mm) T (mm) cross-check\n8-004
