PTFE Thread Sealing Tape

Stainless Steel Pipe Thread Sealing Tape

Mill-Rose Stainless Steel Thread Sealing PTFE Tape is a unique thread sealing tape which prevents stainless steel fittings from galling or seizing during assembly and disassembly. The tape is thicker (.0045" +/-10% and denser (2.50/grams/cubic centimeter +/-110%) than most tapes. The added thickness and density also ensures an effective seal up to 12,000 PSI. Do not use on Oxygen systems - See Green Oxygen Tape in this section.
