What Are DIN Fittings?

DIN, or German Industrial Standard fittings, are hydraulic fittings designed to connect hoses, tubes and pipes in hydraulic systems securely without leakage &#; essential in high-pressure applications. DIN fittings consist of three components &#; fitting body with tapered thread, nut with straight thread that matches up perfectly with the sleeve thread pattern, and sleeve with tapered thread pattern that matches up perfectly with its body thread.

How Do DIN Fittings Work?

DIN fittings work by compressing a soft metal sleeve around a hose or tube, creating a seal resistant to high pressure and vibration. The nut secured onto the fitting body then tightens down tightly ensuring a leak-free connection that&#;s ideal for high pressure applications. They&#;re easy to install or uninstall as well, making DIN fittings popular choices within hydraulic industry applications.

Types of DIN Fittings:

There are various kinds of DIN fittings, such as:

&#; DIN fittings use a cutting ring to compress onto the tube during assembly. With a 24° cone seat, they offer a secure connection against high pressures and vibration. These fittings are commonly used with metric-sized steel tubing.

&#; DIN fittings have a 24° cone seat like DIN fittings, but with an added O-ring seal. This combination ensures a leak-free connection in hydraulic systems. The O-ring provides a tight seal, resisting leakage under high pressure and keeping out external contaminants.

&#; DIN is a standard for metric tube fittings in hydraulic systems. They connect metric-sized tubes to pumps, valves, and cylinders. These fittings have a 24° cone and are used in high-pressure applications.

Advantages of DIN Fittings:

&#; High-pressure resistance

&#; Secure and leak-free connection

&#; Easy to install and remove

&#; Durable and long-lasting

&#; Can be used in various applications

Disadvantages of DIN Fittings:

&#; More expensive than other types of fittings

&#; Require special tools for installation

How to Install DIN Fittings?

Installing DIN fittings requires some specialized tools, but it&#;s a relatively straightforward process. Here&#;s how to install DIN fittings:

&#; Cut the hose or tube to the desired length.

&#; Slide the nut and sleeve onto the hose or tube.

&#; Insert the hose or tube into the fitting body.

&#; Tighten the nut onto the fitting body using a wrench or specialized tool.

&#; Check for leaks and adjust the fitting as needed.
