The Big Orange
filter #101 is sold as a replacement for Sealand’s holding tank filter, so no
extra fittings are required to install.
But for those wishing to install the #101 filter in a vent line with no pre-existing
one, these fittings are required.
They are 5/8” barb
to 3/4” FGHT(Fem. Garden Hose Thread), the swivel nut allows for removal
without the need to loosen any hose clamps.
