Engineering focus
- • AS568 and ISO 3601 sizing
- • Prototype and custom moulding
- • Seal-design and material resources
Size and part-number context
Keep standard AS568 or ISO designations separate from non-standard ID × CS sizes when importing a supplier size into a calculation.
Material and compound context
Ordering information needs size, hardness and material. Confirm availability and shrink-related dimensional data for non-standard compounds.
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.
