Siemens 7ML18301DT Locknut

Siemens 7ML18301DT Locknut is a nylon, 2-inch NPT locknut designed to secure a probe in Siemens level gauge or transmitter assemblies that use 2-inch NPT ports. Identified by the manufacturer product designation 7ML18301DT, with an alternate supplier number 7ML1830-1DT and GTIN 4019169849906, this accessory is described by Siemens as a LOCKNUT, 2-inch NPT, Nylon component. The nylon construction offers chemical resistance and a low-friction interface within 2-inch NPT fittings, making it suitable for ensuring a stable, corrosion-resistant connection for probes in level measurement setups. This part is cataloged in Siemens FI01 literature as a 2-inch NPT nylon locknut and is positioned as an accessory rather than a standalone sensor, aligning with its role in securing a probe in the measurement assembly. The 7ML18301DT designation places it among Siemens' locknut offerings for 2-inch NPT connections used with SITRANS level instruments and other Siemens process equipment that employ 2-inch ports.
