A spray gun can be perfectly tuned and still behave badly if a tiny seal is tired. The AirCraft SG AB17G-10 O-ring is a replacement seal designed for the AB17G spray gun, helping to maintain airtight and fluid-tight joints where they matter most.

When an O-ring hardens, flattens or tears, you may see air leaks, fluid seepage, inconsistent performance or messy drips. Replacing the worn seal is a quick, cost-effective fix that helps keep your AB17G spraying cleanly and consistently.
