A high-pressure sealant containing PTFE, graphite and rust, corrosion, and oxidation inhibitors. All are blended in JET-LUBE's complex grease manufactured using highly refined, low-sulfur oil to ensure brushability over a wide temperature range, tenacious adherence to all surfaces, resistance to water washout, and prevention of rust/corrosion. TF-15 is highly recommended for use on fiberglass casing and tubing on cut threads. Formed threads can have tighter clearances and require the use of TF-15 Arctic. It assures tight makeup at low torque and allows easy breakout without seizing, stripping, or galling. It provides a permanent seal and maintains joint efficiency under vibration, pressure, surge, and temperature fluctuations. It is particularly useful in areas subject to H2S*, salt water, a wide variety of oils, solvents, gases (except oxygen), acids, alkalis and steam. Ideal tubing connections - threaded.
