TF-15 is recommended for all critical tubular components from non-precision, loose and worn threads to high precision threads, particularly those subjected to impact or rough handling upon makeup. Formulated to aid in the make-up of large diameter casing. Provides excellent protection against galling and wear, seals badly worn threads, and greatly increases connection life. Use as a sealant on fiberglass tubing and casing threads. Particularly useful in H2S and salt water environments and in applications subject to vibration, pressure surge and temperature fluctuations.
