Applicator tips useful for surgical application of a viscous substance

An applicator tip for connection to a syringe barrel having a distal end including a cannulated spout spaced from and surrounded by a connector having an internal connector thread on an internal wall of the connector, for dispensing a viscous material from the syringe barrel, the applicator tip comprising:

• a tip body defining a proximal opening, a dispensing opening spaced from the proximal opening, and a tip body lumen extending from the proximal opening to the dispensing opening, the tip body further including a proximal coupling portion defining an exterior thread cooperable with the internal connector thread of the syringe barrel to establish a threadedly attached condition of the applicator tip to the syringe barrel in which the tip body lumen is in fluid communication with an output opening of the cannulated spout;
• wherein the tip body lumen is defined by an interior lumen wall, and wherein the interior lumen wall includes a sealing surface portion configured to contact and seal against an exterior surface of the cannulated spout in the threadedly attached condition.
