A full part number is generated by inserting the material identifier between AS568- and -*** with *** being the size of the O-Ring. Some examples of the many materials we can make any of these O-Rings in are:
Examples of Some Common Material Identifiers: |
|
NE50: | Neoprene, 50 Durometer |
NE70: | Neoprene, 70 Durometer |
NI60: | Nitrile (Buna-N), 60 Durometer |
EP60: | EPDM, 60 Durometer |
1056: | Silver Plated Aluminum filled Silicone |
1167: | Silver Plated Copper filled Fluorosilicone |
FS70: | Fluorosilicone, 70 Durometer |
SI70: | Silicone, 70 Durometer |
AS568-SI70-022 – This indicates a -022 size, as per the chart above, in a 70 Durometer Silicone
1056-0050 – This indicates a -050 size, as per the chart above, in a Silver Plated Aluminum filled Silicone
