Union nuts for 37° flared tube fittings enable reliable, leak-free connection of tubes with 37° flare and conventional fitting bodies as per ISO 8434-1 / DIN 2353 with 24° taper. Efficient sealing action – also when subject to vibrations, pressure shocks and fluctuations. Only the use of STAUFF original parts ensures a high level of tear-out strength for the complete fittings for rated pressures up to 630 bar and makes the fitting system suitable for extreme stresses.
