Graco Seal Lube

Graco Seal Lube is a handy lubricant stick designed for the FlexLiner Cup System. It is a common issue of the FlexLiner lid seal becoming dry and causing issues when attempting to build pressure in the cup assembly when spraying. This can cause leaking in between the cup and lid, air flowing in to the assembly causing tip blockages and stuttering of the pump, and many more issues.

Keep your seal lube stick on hand, apply regularly to the cup system seals, and have the peace of mind that your spraying will hold consistent pressure!
