DKOS 90 is a metric female swivel fitting designed for heavy-duty, high-pressure hydraulic hose and pipeline connections. DKOS 90 features an internal 24° cone seat equipped with an elastomeric O-ring, providing a redundant, leak-free seal that effectively handles severe vibration, thermal expansion, and extreme pressure spikes. Designed in accordance with international metric standard (DIN 2353/ISO8434-1), the heavy-series construction features thicker tube walls and heavier swivel nuts compared to its light-series counterpart (DKOL).
