PC4 Pneumatic Fitting Plug

Simple plug to go into any PC4 pneumatic fitting to block air flow. These are mainly used for plugging the fittings on my cereal container dry boxes while they are not in use so they don't let moisture in. Nice snug fit towards the end of pushing it in but still easy to pull out with your fingers. *UPDATE* 11-26-2023 7:20PM ----- Updated profiles to 102% scale.
