Avanti HVLP AV-100 spray gun bottle lid cap

This lid is designed to fit the Avanti AV-100 handheld HVLP paint and stain sprayer from Harbor Freight. It screws securely over the factory paint/stain bottle, allowing you to seal the container when cleaning, transporting, or storing the sprayer, though for long term storage you may still want to clean out the container. It is probably not 100% air tight so paint will eventually dry out (untested). It should definitely help more than just leaving the bottle exposed to open air at least.

Perfect for prolonging leftover paint or thinner from drying out quickly and preventing spills during cleanup. The design provides a snug, leak-resistant fit and is ideal for DIYers, painters, and homeowners who want to keep their Avanti setup neat and ready for the next project.
