The 3M PPS 2.0 S15 adapter fits the Fuji Spray
MP-V8,
MP-V8 STEALTH,
H-V8,
VALOR M100 and
VALOR H100, so the gun takes 3M's disposable PPS 2.0 cups: mix in a liner, spray, throw the liner away, with no cup to clean. It is stainless steel and stays on the gun; each cup locks onto it with a push and a quarter turn.
It threads into the fluid coupler in place of the gun's cup: remove the cup, thread the adapter in by hand, and snug it with the wrench.
Fuji's how-to on a V8 shows the install.
On a Fuji compressor gun the adapter takes the standard PPS 2.0 hard cup from a
Mini,
Midi or
Large Cup Kit, with no H/O cup needed. Drop a liner into the cup, lid it, then push the gun onto the lid and give it a quarter turn.
