Shop Straight Male JIC - Male DIN Adapters
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 (L series) DIN adapters are rated for lower pressure, while heavy duty (S series) adapters use larger threads and heavier bodies for the same tube OD and carry higher pressure ratings (ISO 8434-1). 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.
Straight male JIC x male DIN adapters join a 37° JIC (SAE J514) connection to a metric DIN 24° cone tube connection. Pick the DIN series first, light duty (L) or heavy duty (S), then the tube OD: a tube nut marked L15 means a 15 mm tube in the L series. Light duty: 9605S or 7005-L. Heavy duty: 9606S or 7005-S. To identify metric threads, see the adapter guide.
Frequently Asked Questions
How does each end of a JIC x DIN adapter seal?
The male JIC end has a 37° flare seat and parallel threads per SAE J514; it seals where the male flared seat contacts the female coned seat. The male DIN end (ISO 8434-1 / DIN 2353) has a 24° tapered throat inside the threads. When a tube nut is tightened over the metric threads, it forces a cutting ring to grip the tube, which holds the assembly and creates the seal.
What is the difference between light duty and heavy duty DIN adapters?
Light duty (L series) DIN adapters are rated for lower pressure. Heavy duty (S series) adapters use larger threads and heavier bodies for the same tube OD and carry higher pressure ratings (ISO 8434-1). DIN 24° fittings belong to one of three pressure series: LL (extra light), L (light) and S (heavy). Order the same series as the tube nut and fitting you are connecting to.
How do I read the DIN tube size?
The tube nut usually shows the tube series and the tube outside diameter together. For example, L15 means a 15 mm OD tube in the L (light duty) series.
How can I tell a DIN fitting from other metric or BSP threads?
Look inside the male thread for a 24° tapered throat; that cone identifies a DIN tube fitting. Metric and British threads share many characteristics, so also measure the thread outside diameter with calipers and check the pitch in millimeters with a thread gauge, then compare the result to the chart in the adapter guide.
Do I need a cutting ring?
To make up a DIN tube connection, the tube needs a tube nut and a cutting ring (ferrule) on the 24° cone end. Cutting rings are listed in the DIN cutting rings collection.
