The Adaptall Series 9606S Straight Male JIC x Male DIN Heavy Duty hydraulic adapters, made from carbon steel, are designed to ensure secure fluid connections in hydraulic systems. These adapters feature a male JIC (Joint Industry Council) end that utilizes a 37-degree flare seating surface and parallel threads, as defined by SAE J514, which are commonly used in fluid power applications for their strength and reliability. The seal is established by contact between the male flared seat and the female coned seat, creating a robust mechanical connection. The metric side incorporates a DIN Tube Heavy Duty connection that adheres to ISO 8434-1 / DIN 2353 standards. DIN tube fittings have a 24-degree tapered throat inside the male fitting, which helps identify it as a DIN fitting when paired with metric threads. It's important to distinguish that heavy duty DIN adapters are built with thicker walls, allowing them to withstand higher pressures and harsher conditions compared to light duty DIN adapters, which are designed for lower pressure applications with a thinner wall construction. To determine 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 reliable and durable hydraulic solutions across various applications.
