Orange Seal - Tubeless Valve Stems
Orange Seal Cycling's new RVC tubeless valve stems are a why-didn't-I-think-of-that level product. Orange Seal removed the rubber rim gasket molded to the end of the stem and mounted it externally. Inner diameter is maximized for improved air flow and decrease potential for clogs in one simple product.
Compared to a Stan's (or standard) valve stem the increased air flow is notable.
The old version of the RVC valve stems aren't anything to write home about.* The most obvious difference is the permanently attached rim gasket of the old versus the swappable gaskets of the new.
My favourite detail of the RVC package is the extra set of valve cores. There's also a plastic core removal tool and two different gasket profiles.
Simple in design and execution. Faster to air up. Less prone to clogging. Easier to clean out. I'll be surprised if most** companies hawking valve stems don't eventually transition to a similar design.
