Straight DKJ fittings ( C91) 

DKJ UNF fittings are high-quality hydraulic fittings used in hydraulic systems, characterized by a 74° sealing cone and UNF thread (Unified National Fine). They are widely used in various power hydraulics applications where a reliable and leak-proof connection of hydraulic hoses with other system components is required. DKJ UNF fittings are distinguished by their precise construction, which ensures high tightness and resistance to operating pressures typical of power hydraulics. A key construction element is the 37° sealing cone, which allows for effective fitting to matching components. Thanks to the use of UNF thread, these fittings feature a fine thread pitch, which ensures connection stability and minimizes the risk of leakage under vibrations or dynamic loads. DKJ fittings are also available in elbow versions DKJ 90° degrees and DKJ 45°
