1000 pcs Second Quality 60 Mesh screens compatible with Graco 246358

These screens were manufactured with a slightly too large inside diameter (slightly too wide).  They are the right length and mesh but do not stay on the check valve when vertical.  Consequently, they have to be pinched to stay on.  They work, but at an inconvenience.  Consequently, I am selling them very cheaply.  100 @.50 ea / 500 @.45 ea / 1000 @.40 ea.
