Union nut M10x1 for 6LL tube – stainless steel 1.4571

The M10x1 union nut for 6LL tube is a hydraulic fitting element made of 1.4571 stainless steel, designed for making screwed tube connections with a cutting ring. The nut works with a tube with an outer diameter of 6 mm and a compatible very light series LL connector body. Thanks to the use of stainless steel, the product performs well in installations requiring increased corrosion resistance.

The product features an M10x1 metric thread and is designed for operation at 100 bar pressure and temperatures ranging from -20°C to +120°C. It corresponds to the catalog designation Cast 100202 SS and Parker Ermetto M06LL SS, which facilitates element identification and selection of the appropriate fittings during construction, modernization, and maintenance of piping systems.

Technical parameters of the M10x1 6LL nut

Product type: hydraulic union nut.
Catalog code: 100202 SS.
Cast designation: 100202 SS.
Parker Ermetto designation: M06LL SS.
Thread: metric M10x1.
Tube outer diameter: 6 mm.
Connection series: LL – very light.
Material: 1.4571 stainless steel.
Working pressure: 100 bar.
Operating temperature: from -20°C to +120°C.
Connection type: screwed, with a cutting ring.
Connector system: EO, 24° cone.
Standards indicated in commercial documentation: PN-65/M-73139, DIN 2353 and DIN EN ISO 8434-1.

Catalog designations Cast 100202 SS and Parker Ermetto M06LL SS

The union nut is available under catalog code 100202 SS. The Cast designation is 100202 SS, while the corresponding Parker Ermetto designation is M06LL SS. This information is particularly useful when identifying elements in technical catalogs, assembling hydraulic connections, and searching for spare parts.

Catalog designations allow for a more precise determination of the nut type than the thread dimension alone. When comparing elements from different manufacturers, however, the compatibility of the LL series, cutting ring design, and mating surfaces should be checked. An identical thread is not independent confirmation of the interchangeability of all parts.

Application of stainless steel nuts in hydraulic systems

The M10x1 6LL nut is used to complete detachable tube connections in hydraulic and industrial installations. It can be used in compatible systems of production machines, technological equipment, hydraulic power units, and installations utilizing small-diameter tubes.

The product is used when making new connections, replacing nuts, and repairing existing pipe fittings. The possibility of application in a specific system is determined by the parameters of the entire connection, including pressure, type of medium, tube material, and the strength of the mating elements.

Stainless steel 1.4571 – properties and corrosion resistance

The nut is made of 1.4571 grade stainless steel, also known as X6CrNiMoTi17-12-2. It is a titanium-stabilized austenitic chromium-nickel-molybdenum steel. The material is characterized by increased corrosion resistance compared to standard carbon steel and is used for the production of industrial fitting components.

The stainless steel construction is a beneficial solution in environments exposed to moisture and selected corrosive agents. However, it does not mean resistance to all chemical substances. When working with aggressive media, the material compatibility of the nut, tube, ring, and connector body must be confirmed.

M10x1 thread and 6LL very light series

The M10x1 metric thread has a nominal diameter of 10 mm and a pitch of 1 mm. The nut is intended for a tube with an outer diameter of 6 mm in the LL series. The very light series is a separate group of tube connections, so the nut should not be selected solely based on the thread diameter.

Before installation, compatibility with the connector body and the cutting ring intended for this system must be confirmed. Special attention should be paid to the differences between the LL, L, and S series. Individual solutions may use different dimensions and designs of mating elements.

Connection with a cutting ring and 24° cone

The M10x1 6LL nut is designed for tube connections with a cutting ring. During proper assembly, the nut exerts pressure on the ring, which interacts with the tube surface and the connector body. This allows for mechanical fastening of the line and the creation of a detachable connection.

The product catalog description indicates compatibility with the EO system equipped with a 24° cone. This angle refers to the geometry of the appropriate connection system, not the nut thread. To maintain tightness, a compatible cutting ring, tube, and connector body must be used.

Working pressure 100 bar and operating temperature

For the M10x1 6LL union nut, a working pressure of 100 bar and a temperature range of -20°C to +120°C are specified. These parameters should be treated as data regarding the described element. The permissible operating conditions of the finished connection must also take into account the limitations of the tube, cutting ring, and connector body.

Correct selection and assembly of the M10x1 6LL nut

Before assembly, ensure that the tube has an outer diameter of 6 mm and that the used ring and body correspond to the LL series. The end of the tube should be properly cut, cleaned, and deburred. The nut and ring should be installed in the order specified in the assembly instructions for the given connection system.

During tightening, the manufacturer's recommendations for compatible fittings must be followed. Stainless steel components require special attention due to the possibility of thread galling. After making the connection, the correct seating of the tube must be checked and a leak test must be carried out according to the procedure applicable to the installation.

Frequently Asked Questions (FAQ)

What is the Cast designation for the M10x1 6LL nut?

The catalog designation according to Cast is 100202 SS. The same number appears as the product catalog code.

What Parker Ermetto designation corresponds to the 100202 SS nut?

The designation according to Parker Ermetto is M06LL SS. When selecting, additionally check the compatibility of all connection elements.

What tube does the M10x1 6LL nut fit?

The nut is intended for a tube with an outer diameter of 6 mm, working with an appropriate LL series cutting ring.

Does the 6LL nut fit every M10x1 connector?

No. M10x1 thread compatibility does not guarantee compatibility with every connector. The LL series, ring design, and body geometry must be confirmed.
