What the heck is this thing?

This is a preassembled, prebled, unserviceable clutch hydraulics assembly for an 05 Liberty 3.7 4x4 Renegade with 6-speed manual transmission....

What I'm trying to figure out, however, is what in the hell this little gold widget is... Closer views.....

I've had people tell me it's a one-way valve (can't possibly be, as you'd clutch one time and never move the car again) or an accumulator (unneeded and as far as I'm aware, not possible in line).

Does anyone KNOW? I am making my own line to install separate/serviceable parts, and an not sure if this is part of the problem I had last weekend when it wouldn't work (I'm 99% sure that problem was due to oversized line leaving me with not enough stroke at the SC)...

Don’t KNOW but right off the bat, I’m gonna guess that it’s a sort of mini pulse damper to keep pulses from the throwout bearing/fork/clutch/flywheel from traveling up and down the line if the movement effect the slave cylinder piston

Again just my best guess

Like this—

They come as small as 1/8” diameter and while are mostly used for pump installations, there is no reason they couldn’t be used for manual piston applications where a pulsation might be introduced by another rotating mass
