Kohler Valvet, What stem is this?

[Youngr1285]

Please help. I need to replace this valve but I can’t find out what it is. I think it’s a 18 spline Kohler but that’s the most I know. Thank you.

These are "Valvet cartridges Kohler old # GP30002 and GP30004. Kohler revamped these to GP330002 and GP330004. Your bonnet nut is # 34253

Will the old bonnet nut fit the GP330002?

 

[Marlinman]

The old bonnets will fit. Make sure the stem o-ring is pushed into place inside the bonnet.
