    Maybe one of you guys have seen this check valve before. This is off of a NorthStar skid sprayer. I think I must be missing an o-ring somehow or it must have grown:confused:

    I noticed this when I was cleaning the filter out. It looks like the o-ring should fit around the edge of the blue filter screen, but it's too big. Maybe it fits into one of the grooves on the black filter housing??? I can't tell where this thing goes.

    I checked the manual and the exploded view shows this part as a whole, not helpful:hammerhead:

    You wouldn't think they would use that kind of rubber. I'll pick up a new one. Thanks for the info.:)
