We have lots of huge quick connect hydro lines to connect on cranes. Leave the equipment off, then on the male side take a big flat screwdriver and push in on the fitting letting some pressure in the line to leak out. Hose will go straight on. And we do some that are 4” or bigger.
You have pressure in the lines one way to avoid. This is shut down the machine properly and disengage auxiliary hydraulics next just crack the fitting open with two pairs of pliers on the hose side to relieve the pressure and it will slide on.
I have a 4 year old pig named Bella and I plan to not eat her even tho I love pork I still love my animals and want to spend every last minute with them
