Fusion AP Round Mix Chamber 01, 0.042 in, Graco Part AR4242


This is the round pattern mix chamber for the Graco Fusion AP air purge spray gun, in the 0.042 in orifice size. Graco identifies it as size 01, and the exploded parts diagram lists it as the mixing chamber with a 0.042 orifice size, 01.

Mix chamber sizes are not interchangeable, so go by the size code: 01 is the 0.042 in chamber in the Fusion AP round range. Confirm what your gun is set up with before ordering, and if you are changing sizes, order the size the job needs rather than replacing like for like out of habit.

This chamber is listed for the Fusion AP. Genuine Graco OEM part AR4242.
