Engineering focus
- • O-ring handbook and design references
- • AS568 sizes and compound selection
- • Static, dynamic and face-seal guidance
Size and part-number context
Keep Parker part data and AS568 designations separate: a dash size defines geometry, while a Parker part number also identifies a commercial product and compound.
Material and compound context
Use official compound data for final chemical, temperature and approval decisions; generic FKM, NBR or EPDM family data cannot replace a compound sheet.
Use this brand data in a design review
- 1Identify the exact supplier part number, standard designation, material code and hardness.
- 2Enter the verified ID, cross-section and tolerances in the seal-specific calculator.
- 3Check squeeze, stretch, gland fill and extrusion without changing limits because of the brand.
- 4Confirm availability, certification and final compound data with the manufacturer or an authorized source.
