Introducing the Classic Aluminum Cap Adapter. These rusto adapters are machined out of solid 6061-T6 aircraft aluminum, making them practically indestructible compared to the plastic adapters. Proudly manufactured in America by the fine folks at Classic Adapters.

This adapter is compatible with ⅛’ (3.2mm) male valve Rustoleum cans. Same compatibility you will expect with the blue Uproks or WingCap adapters. Will not work with Valspar, Universal Formula, or any other male valves that have the 4mm stem.
