TF-25's lubricating and sealing properties will prevent thread leaks of fluids, gases, or steam. It can be used for a multitude of low friction, anti-seize applications requiring maximum performance. It protects all threads from premature wear and prolongs the life of tapered-thread joints under all conditions. Ideal for press fittings.
