One becomes 2 when adding this reverse wye connector. As a counterpart to our wye, this will hook to any internally threaded port on our masks. Shown here on a KG1, dual hoses can be added for use with any other threaded, compatible add-ons on the male (shown here with one of our painted black canisters.).
This item comes in basic black but the rubber wye shape can be made with your choice of basic colors.
