The Series 5066S 45-Degree Angled Male Heavy Duty DIN x Male Adjustable Metric adapters, made from robust carbon steel, are designed for fluid systems requiring durable, leak-free connections. These adapters feature a male DIN Tube Heavy Duty connection that complies with ISO 8434-1 / DIN 2353 standards, including a dual-purpose ball seat. The male DIN fitting has a 24° tapered throat inside, which, when paired with a metric thread, clearly identifies it as a DIN fitting. The connection is secured by tightening a tube nut over the metric threads, compressing a ferrule or cutting ring that grips the tube and forms a seal. These adapters are categorized into pressure classes—LL for extra light duty, L for light duty, and S for heavy duty—making them ideal for high-pressure applications. The adjustable feature ensures flexibility in installation, while the design ensures high-performance sealing, making these adapters suitable for demanding fluid power systems.
