Mill-Rose Blue Monster Silver-Seal PTFE Tape was developed specifically for creating dependable, leak-free joints on today's high-end plumbing fixtures made with chrome, stainless steel, and nickel finishes. The silver color of this professional-grade tape blends with high-end finishes minimizing any exposure. Unsightly thread seal tape previously exposed on high-end fixtures, cheapening their appearance, is a thing of the past.
