Marquest Recomendation: This tape is very good when sealing threads that are exposed to Mineral Oil, Halocarbon Oil, & Silcone Oil. 2-3 wraps of this tape prevents "wicking" from occuring and subsequent leaking of the threaded joint.
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.
Blue Monster is not too thick and not too thin. It was developed by Mill-Rose in response to the demand for a higher-quality PTFE sealing tape that is easier to apply.
Blue Monster is rugged, not flimsy like most thread seal tapes on the market. Blue Monster has not been stretched during the manufacturing process, so it is thicker and creates a more effective seal with less tape, and no need for pipe dope.
Blue Monster thread sealing tape is manufactured from PTFE resin, a polymer consisting of recurring tetrafluoroethylene monomers whose formula is (CF2-CF2)n. It is inert and compatible with a very wide range of materials. Use Blue Monster on threads made from galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, polypropylene, PVC, CPVC, ABS, fiberglass and more.
