This is an OEM outlet seat made to fit many of the Titan and some SprayTech models. It fits in the 704-551A piston. If you want a complete piston with the seat and ball cage and retainer already installed look at our 704-560 rod. Here is a list of some of the units this fits.
This part replaces the outlet seat in the machines below:
Titan 440, 447, 440i, 440ix, Impact 440, all 540 units, all 640 units, GPX85, GXC690 , Advantage 400, 445, XT440, Advantage 340

***The only exception is the older Titan units that had the 704-089 piston rod. This is the older rod with the thinner piston wall and was replaced by the 704-551A rod.***
