Mack's Lure 3/16-Inch Surgical Tubing, Black, 3-Feet Surgical tubing is made from latex and comes in a variety of diameters and thicknesses. Surgical tubing is used to make homemade lures, as well as for tying and securing equipment on the boat. Because of its flexibility, surgical tubing replicates the swimming action of a fish when it is submerged; this also makes it particularly well-suited for making rubber eel lures. Usually a fishing jig head is attached to the end of the surgical tubing for a homemade lure. 3/16 Diameter
