Guideline 4D Interchangeable Tips are developed for use together with our 4D Multi Tip Bodies and Connect DDC Lines. These tips have phenomenal turnover and sink fast and correct. All sinking tips have Dual Densities to ensure a straight sinking path. They have outstanding turnover core strengths matching the strength in the bodies and high durability. To achieve the best possible performance available in tips on the market today, we have developed the taper from the actual front sections of our original Triple Density lines. There are a total of seven different densities, two different lengths and four different weights to choose from in this range. All Tips have strong, reinforced loops in both ends and have printed ID marking on the sleeves for easy identification of weight, length and density. They are also color coded for easy matching with various GUIDELINE 4D- and Connect DDC Bodies.
