Merchant steel fittings are designed with Dryseal Taper Threads (NPTF) for more critical applications where the sealing compound may fail due to high heat or pressure, NPTF Dryseal threads produce a mechanical seal by the mating and slight crushing of the threads when a wrench is applied to tighten the fittings.
