Single-lumen tubing is a type of tubing that features a single internal passage or lumen.

Profile extrusions refer to the manufacturing process of creating plastic shapes with a continuous, typically complex cross-section.

Bump extrusions, also known as tapered or stepped extrusions, involve tubing with two or more outer diameter sizes along its continuous length.

Multi-lumen tubing refers to tubing that contains two or more lumens, which are separate channels or passages within the tube.
