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 |
Examples of full part numbers are:
AS568-SI70-457 – This indicates a -457 size, as per the chart above, in a 70 Durometer Silicone
1056-0470 – This indicates a -470 size, as per the chart above, in a Silver Plated Aluminum filled Silicone (see EMI/RFI Shielding section for more information)
