Products Features

Various threads

Metric hydraulic fittings are specifically designed to ensure tight and secure connections in fluid conduits. These fittings are available in a variety of standardized thread types to accommodate different mechanical and hydraulic requirements worldwide.

Parallel (M Series)

The Metric Parallel thread, or M Series, features a straight thread design and is commonly used in hydraulic systems. It requires a sealing mechanism, such as an O-ring, to ensure a leak-proof connection.

Tapered (MT Series)

Metric Tapered threads, known as MT Series, taper towards the end, allowing the thread itself to form a seal. This design eliminates the need for additional sealing components, which can simplify assembly and maintenance.

24° Cone (DIN 2353/ISO 8434-1)

This type of fitting uses a 24-degree cone and is part of the DIN 2353 fittings standard. It provides a very effective seal via the cone’s interaction with the mating tube or hose end.

60° Cone (BS 5200)

Featuring a 60-degree cone, these fittings are designed according to British Standard 5200. They offer an alternative sealing mechanism, where the cone aligns with the mating piece to form a tight seal.


Metric hydraulic pipe fittings are essential components in a variety of industrial applications, offering robust and reliable connections across numerous sectors. Their versatility and durability make them particularly valuable in environments that demand high performance and precision.

Brass Hydraulic Fittings


Metric hydraulic pipe fittings are typically made from stainless steel, carbon steel, and brass. Each material is chosen based on its durability, corrosion resistance, and suitability for specific environments and hydraulic fluids.

Metric fittings are available in a range of sizes, typically from 6mm to 42mm. These sizes refer to the outer diameter of the tube that the fitting will connect to.

Selecting the right fitting involves considering the size, pressure rating, and the type of fluid used in your system. It’s also crucial to match the fitting type (e.g., straight, elbow, tee) to the required application configuration.

Most Metric hydraulic fittings are compatible with a variety of hydraulic fluids, including mineral oils, water-based fluids, and synthetic fluids. However, it’s important to check compatibility with specific materials used in the fittings for any special types of fluid.

The pressure rating of hydraulic Metric fittings varies depending on the material and design. Ratings can range from low pressure (up to 150 bar) to high pressure (up to 630 bar or more), suitable for different industrial applications.

Metric fittings are based on millimeter measurements and typically use Metric threading, which differs from the inch-based measurements and thread types used in other standards like NPT (National Pipe Taper) in North America.

While some Metric fittings may physically fit with other types of fittings, it’s not recommended to mix different standards due to potential differences in thread types, sealing methods, and pressure ratings which can lead to leaks and system failures.

To ensure a leak-proof installation, Metric hydraulic fittings should be tightened to the manufacturer’s specified torque. Using proper tools and methods like the two-wrench method for tightening can also prevent over-tightening and ensure a secure fit.

Regular inspection for leaks, corrosion, and wear is recommended. It’s also important to ensure that the fittings are clean and free from debris. Re-torquing fittings periodically can help maintain a leak-proof seal.

High-quality metric hose fittings can be purchased from Topa. We specialize in hydraulic components and offer a wide range of sizes to meet different needs.
