The Adaptall Series 9197 Straight Male JIC x Female Metric DIN/DKO Tube Swivel hydraulic adapters, made from durable carbon steel, are vital components for ensuring secure and efficient 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. On the metric side, the adapter includes a DIN Tube Light Duty connection with a dual-purpose ball seat, conforming to ISO 8434-1 / DIN 2353 standards. The DIN tube fittings are characterized by a 24-degree tapered throat inside the male fitting, which clearly identifies it as a DIN fitting when a metric thread is also present. To determine the series and tube size, the tube nut typically displays the tube series and size, combining TUBE SERIES with TUBE O.D. (e.g., L15 for a 15mm tube in the L series). These adapters provide flexibility and ease of installation, making them an ideal choice for professionals seeking reliable hydraulic solutions in various applications.
