I am writing a study for college on Aircraft parts and I am covering bonding leads. It says bonding leads are available to:

AGS, LN, CSP, JN -- what are these? are they abbreviations?

Also....

Seals in the CSP, AS, SP, PAN, MBB, VFN, JN, BS range ---- what are these abbreviations?

Any help would really help me, I'm clueless!

Thanks
