Do you suffer from an excess of ports in something? Do you need a sexy blue anodized plug to close off your extra orifices? Look no more!
Seriously, they’re plugs for NPT ports. Available in 1/8 NPT, 1/4 NPT or 3/8 NPT size. They’re small so the shipping charges will seem exorbitant, so we recommend you buy them at the same time as something else.
