The NIP® Barb is an enhanced version of the needle‑free connector that incorporates ergonomic features to improve handling and usability. Like the standard NIP®, it ensures a hermetic seal both before and after connection, providing a secure and leak‑resistant interface for accessing fluids without needles.

This version includes three different barb sizes: 1/8 inch, 3/16 inch, and 1/4 inch, available with or without wings, offering easier grip and connection while accommodating different tubing diameters. These additions make the device more adaptable and easier to manipulate during clinical procedures, particularly in settings where precision and speed are important.
