In this case thesealing is ensured on the metal to metal contact between the cones.WARNING: Torque values need to be reduced by 50% in the NPTF/NPSM connections and by 25-30% if sealant ispresent.Las roscas NPTF y NPSM son conexiones Americanas que tienen un ángulo de 60º entre los hilos.El macho NPTF y la rosca hembra son cónicos y controlan el trucamiento para asegurar el contacto metal con metal entrecresta y raíz y crear la estanquidad en la rosca.El macho NPTF tiene un asiento cónico de 30º también para la unión con la hembra NPTF/NPSM (rosca cilíndrica). En estecaso la estanqueidad se realiza con el contacto metal con metal entre los conos.ADVERTENCIA: Los valores de apriete necesita ser reducidos un 50% en las conexiones NPTF/NPSM y un 25-30% si seaplica sellante.Inch sizeTamaño pulgadasDashmóduloNominal threadsizeTamano roscaMale threado.d.Rosca MachoFemale threadi.d.Rosca hembraWorkingpressurePresión máxima trabajoSuggested tourquevalues (Nm)Par de aprietemáximamm inch mm inch bar psi min.1/8” -02 1/8”-27 10,4 0,41 9,2 0,36 345 5000 201/4” -04 1/4”-18 14,0 0,55 12,2 0,48 345 5000 303/8” -06 3/8”-18 17,3 0,68 15,5 0,61 275 4000 401/2” -08 1/2”-14 21,6 0,85 19,2 0,76 240 3500 553/4” -12 3/4”-14 26,9 1,06 24,6 0,97 155 2250 701” -16 1”-11,5 33,8 1,33 30,7 1,21 135 2000 901.1/4” -20 1.1/4”-11,5 42,4 1,67 39,4 1,55 110 1625 1001.1/2” -24 1.1/2”-11,5 48,5 1,91 45,5 1,79 85 1250 120200
