We claim the ornamental design of a manifold adaptor for a multi-barrel syringe applicator, as shown and described.
FIG. 1 is a front perspective view of a manifold adaptor for a multi-barrel syringe applicator;
FIG. 2 is a rear perspective view of a manifold adaptor for a multi-barrel syringe applicator;
FIG. 3 is a front elevational view of a manifold adaptor for a multi-barrel syringe applicator;
FIG. 4 is a rear elevational view of a manifold adaptor for a multi-barrel syringe applicator;
FIG. 5 is a left-side elevational view of a manifold adaptor for a multi-barrel syringe applicator, which is identical to the right-side elevational view; and,
FIG. 6 is a top plan view of a manifold adaptor for a multi-barrel syringe applicator, which is identical to the bottom plan view.
