The Piston Rod Assembly is an aftermarket replacement part by CMP for the Hayward SP-410X Slide Valve. This valve is commonly used on the Hayward Micro Clear & Pro Grid DE filters. This is the internal only for the SP0410 Series valves.
I am replacing the o-rings on this valve and cannot figure out where the small o-ring goes.
