Sealing of the DILO unions is made without intermediate seal in the form of tongue and groove with little depth of immersion. This principle guarantees permanent tightness at all pressures, dynamic stresses, high temperatures, high alternating stresses and vacuum.
All fittings are subject to strict quality controls and are provided with inspection certificates according to EN 10204 (DIN 50049-3.1B).
