The Adaptall Straight Male JIC x Male DIN hydraulic adapters are essential components designed to create secure fluid connections in hydraulic systems. Featuring a male JIC (Joint Industry Council) end, these adapters utilize a 37-degree flare seating surface and parallel threads, as defined by SAE J514, which are commonly used in fluid power applications for their reliability and performance. The seal is formed by contact between the male flared seat and the female coned seat, establishing a robust mechanical connection. On the metric side, the adapter includes a DIN Tube Light Duty connection with a dual-purpose ball seat, compliant with ISO 8434-1 / DIN 2353 standards. DIN tube fittings are identifiable by a 24-degree tapered throat inside the male fitting, which helps distinguish them from other metric threads. It's important to note that light duty DIN adapters are designed for lower pressure applications and have a thinner wall construction, making them more flexible, while heavy duty DIN adapters are built for higher pressure environments with a thicker, more robust construction. To identify the series and tube size, the tube nut typically indicates the tube series and size, combining TUBE SERIES with TUBE O.D., such as L15 for a 15mm tube in the L series. These adapters are ideal for professionals seeking efficient and dependable hydraulic solutions in various applications.
