Introduction:
Welcome to our blog about JIS and DIN hydraulic fittings! In this guide, we will look at these two types of fittings, their uses, benefits, and what makes them different. Whether you are a professional in the hydraulic field or just starting out, this guide will give you helpful information.
Understanding JIS Fittings:
JIS (Japanese Industrial Standard) fittings are hydraulic fittings commonly used in Japan and other parts of Asia. Like DIN fittings, they connect hydraulic hoses and tubes in machines used in factories, construction sites, and farms. JIS fittings are known for their 30-degree flare angle and BSP threads. This angle helps create a strong seal between the fitting and the hose or tube, preventing leaks when under pressure. JIS fittings come in many sizes, from small ones for low-pressure systems to larger ones for high-pressure use. They are usually made of stainless steel, steel, or brass and can be male or female fittings.
Exploring DIN Fittings:
DIN (Deutsches Institut für Normung) fittings are hydraulic fittings often seen in Europe. They have a 24-degree cone and metric threads. A DIN fitting connects Metric tubing to fitting thread connections in a way that holds well even when there’s high pressure or lots of shaking. These fittings have three parts: a body, ferrule, and nut. The ferrule’s sharp edges bite into the tubing’s outer surface, making sure it holds tight. Stainless steel DIN fittings are popular in breweries, wineries, and the food, beverage, pharmaceutical, and chemical industries.
Differences Between JIS and DIN Hydraulic Fittings:
JIS and DIN fittings do the same job but in slightly different ways. Here are some key differences:
- Flare Angle: The big difference is the flare angle. DIN fittings have a 24-degree flare angle, while JIS fittings have a 30-degree flare angle. This difference changes how these fittings seal and connect to the hydraulic tubing or hose.
- Thread Type: DIN fittings have metric threads, and JIS fittings have BSP threads. So, you might need different tools and adapters for DIN fittings than for JIS fittings when working on hydraulic systems.
- Standards: DIN fittings follow German Industry Standards, and JIS fittings follow Japanese Industrial Standards. This means there might be small differences in specifications and performance standards between DIN and JIS fittings.
Hydraxio offers a wide variety of stainless steel DIN and JIS hydraulic fittings. We have been providing these for over two decades. If you have any questions, feel free to ask us.
Conclusion:
Now you know more about JIS and DIN hydraulic fittings, their benefits, and how they are different. Understanding these fittings will help you whether you are working on hydraulic systems in Europe or Asia.
