VTP Series vinyl plugs provide a snug fit when pushed into open ports, ensuring a tight closure that will not pop out accidentally during processing or shipping. A simple tug on the flanged lip of an installed VTP breaks the seal for easy removal. The plugs are molded from a specially formulated, non-shredding vinyl that offers an attractive, high-gloss finish to products. : : A: 0.530, B: 0.365, C: 0.555, PLUGNPTTS: 1/4, PLUGSTDTS: 1/2.
