TV Series

Applications

In Italian language TV means “TIPO VECCHIO”(old type) because this series of couplings is the first that MB began to produce from 1956 on his own drawings: TV series is well known in Italy and now MB is the only producer of it. These couplings are suitable for any hydraulic application in industry and in agriculture: the hardiness and the wide range of sizes are their peculiar features. The 1.1/4”, 1.1/2” and 2” sizes are also available in brass and in stainless steel AISI 316.
