This 2″ BSP bung has a two-way high-flow vacuum vent which is usually used to create a higher, smoother flow rate for customers draining IBCs.
The two-way vent allows chemicals to vent outward when stored, but allows air in when decanting so that the sides do not suck in.
Vents at 4psi. Made from glass filled polypropylene with santoprene gaskets.
NB. The white vent (600861) also shown is the standard vented bung that comes with our 6″ lids 500756.
