Gruber Seamless and Integra Mixing Tips Replaces the Green Quad Mixing Tip

The original Static mixing tip for solid surface adhesives was the milky white tip with the orange center. The patents were going to run out and to maintain control the manufacture chaged the tip to a square tip with a different mixing center. The manufacture claimed that the tip mixed bettere but we have found nothing to back that up. The green tip is a buit shorter but the square design makes the tip hold just about the same amount as the round longer tip.These mixing tips can be used on any cartridge you have been using the green square tips. In any event the square tips are on back order indefinately
