Uprok Adapter Wing Cap (Blue 3.2mm)

Uprok Adapter Wing Cap (Blue 3.2mm)

The Uprok Adapter Wing Cap is a simple piece of hardware with serious utility behind it. Designed to bridge old-school cap styles with modern male valve systems, this adapter allows writers to run classic female caps on newer American hardware paint cans with 3.2mm male valves — unlocking wider compatibility, cleaner control, and more options in the field.

Created by UPROK — the legendary graffiti supply shop rooted in Salt Lake City — the Wing Cap reflects the same practical, writer-driven mentality that built their reputation. No gimmicks. Just functional tools built by people who actually paint.
