Hi! New here, first post.  I'm trying to figure out what symbol to use in a hydraulic schematic to represent a "2-inch collet-style connector".  Any ideas on what it looks like?  Thanks!

Have you done an online search using the phrase "hydraulic schematic symbols"?

Yes, I did that several times before resolving to posting on a forum.  Most of the references that come up are for typical DCV, Accumulators, check valve type things.
