2" NPT male (short eye) S60x6 female, check-it, 20B Cap assembly:

New from CPP is this very low profile Check valve seal that can be fitted to our
existing extensive range of IBC adapters or our IBC valves, helping you conform
to the EPA requirements for pesticides shipped in IBC's. Manufactured in food
grade Santoprene giving a wide range of resistance to various chemicals shipped
in the IBC tote while stopping back flow and contamination.
Fitting a Check-it is as simple as changing a seal so you can retro fit and bring
most standard IBC in to a conforming EPA container while still in situ. Because of
our unique design tanks can be 100% emptied with a minimum flow restriction.
We can also supply Check-it ready fitted in our IBC valve.
