I purchased one of those Orange skid steer mulchers from an auction. While going over it to make it as reliable as possible, I was hooking up the hoses and could not connect the motor return hose because both connections are male. I need to swap out the one on the mulcher with a female flat face coupler. The problem is I don't know what end is on the hose. Can anyone identify these fittings?
That screams German metric to me. Whether low pressure or high depends on diameter and thread pitch
European, DIN or BSP German metric would be the DIN
BSPP has no o-ring, and has the inverted cone deeper in the swivel. So... all in on DIN.
And the fun part of DIN? They come in light and heavy fittings, different size fitting for the same tube size.
I think I'll just cut the end of the hose off and start over with a pipe thread.
I wouldn't go with pipe thread on something continuous duty like a mulcher. JIC or ORB would be a better option.
