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. It can be used on pipes carrying the following:

• Acids, concentrated
  (see precautions)
• Acids, dilute
• Air, compressed
• Alcohols
• Aliphatic solvents
• Ammonia, liquid
• Aromatic solvents
• Caustics, concentrated
  (see precautions)
• Chlorinated solvents
• Cutting oils
• Diesel fuel oil
• Ethylene glycol
• Fatty acids
• Gasohol
• Glycerine
• Heating oils
• Hydraulic fluids
• Hydraulic oils
• Hydrogen, gaseous and liquid
• Inert gases, gaseous and liquid
• Jet fuel
• Kerosene
• Ketones
• Liquid Petroleum Gas
• Mineral oils
• Natural gas
• Nitrogen, gaseous and liquid
• Petroleum solvents
• Soap, liquid
• Steam
• Vegetable oils
• Water

Pressure rating: Mill-Rose Blue Monster Thread Sealing Tape has been used to seal fittings carrying water and oil at pressures up to 10,000 PSI or 69,000kPa

Note: Pressure ratings are relative to the quality and torque of the fittings and the amount of tape used.

Temperature Range: -450°F to +500°F (-268°C to +260°C) PTFE is completely stable up to +500o F or +260°C. Decomposition is slow up to 750°F or 400°C. Although decomposition will occur on contact with naked flames.

Fittings above 1½" (38mm) diameter.

1. Use 3/4" (19mm) wide tape for fittings up to 2" (51mm) in diameter. Use 1" (25mm) wide tape for fittings larger than 2" (51mm) in diameter.
2. Follow the directions under "Instructions".

Precautions

Note: Keep Mill-Rose Blue Monster Thread Sealing Tape clean. Replace the clip on the spool after use. Store in a clean place. PTFE is virtually chemically resistant to all media, however there are a few exceptions. Alkali metals such as elemental sodium, potassium and lithium are to be avoided. These alkali metals remove fluorine from the polymer molecule. Extremely potent oxidizers such as fluorine (F2) and related compounds (e.g., chlorine trifluoride(CIF3) can be handled by PTFE, but only with great care. Since fluorine is absorbed into the resin, the mixture becomes sensitive to a source of ignition such as impact. Other media to avoid are 80% NaOH or KOH, metal hydrides such as boranes (e.g., B2H6), aluminum chloride, ammonia (NH3), certain amines (R-NH2), imines (R-NH) and 70% nitric acid at temperatures near the suggested service level.

Do not use Mill-Rose Blue Monster Thread Sealing Tape on oxygen lines!

Mill-Rose recommends Green Oxygen Tape for oxygen lines. For further safety details consult the Material Safety Data Sheet.

Note: Mill-Rose Blue Monster Tape is compatible with most gases, but for gas lines, Mill-Rose 3-Wrap Yellow Gas Seal Tape is recommended.
