Standards Of Tube Nut

Products meet standard of DIN 3870(LL series), DIN 2353 and ISO 8434-1.

Finish is 72 hours without surface coating corrosion acc.to ISO 9227 Fe/Zn8/Cn/T0(T2).

Design of Tube Nut

ISO 8434-1 is instead of DIN 3870 design of tube nut, nuts should be made of carbon steel, stainless steel and copper alloy, to be used with correspond to the fitting bodies.

Raw Material types of DIN tube nut

They are either cold formed, hot formed or machined from cold drawn, it is based on different size for right material shapes.

DIN tube nut for impeccable hydraulic connections


When it comes to hydraulic systems, connections are everything. This DIN tube nut proves the claim as a crucial fitting for the flawless functioning of hydraulic tubes that stand up to the demands of thermally unstable and corrosive environments.


The noteworthy features and functions of this nut include:

  • Connective stability. This nut tube fitting is an essential link between hydraulic components. Its primary function is to guide the cutting ring into the hydraulic tube for a dependable and leak-free connection.

  • Compliance and versatility. Industry-wise, this nut is a compliant solution for your fastening needs. It can work with a myriad of adapters and fittings under the ISO 8434-1 and DIN 3870 standards.

  • Multi-functional design. Beyond its role as a tube fitting, it can also double as a coupling and union nut. This enhances its utility in hydraulic applications and makes it easier to kick your assemblies with double-bite cutting rings up a notch.

  • Material options. Fitsch is an independent supplier of Parker hydraulic fittings, adapters, and DIN nuts in particular. That means you can directly request your hardware to be made of carbon steel for extraordinary robustness that would underpin hydraulic applications where high tensile strength is required or stainless steel for longevity protected against corrosive risks.

  • Superior finishes. To add to the performance and longevity of this nut, you can opt for a zinc-plated version or a Zn-Ni coating. The latter proves to be more dependable when exposed to higher thermal stresses and more aggressive corrosive environments, extending the life of your connections and the hydraulic assembly they serve.


Your projects are not those to be postponed. With Fitsch, the desired surface coating can be implemented within just 72 hours. We leave no stone unturned and no thread element unchecked.


Order tube connecting nuts with series-specific features


This DIN nut comes in globally recognized series, including LL, L, and S, each made for different thread types and OD dimensions. To check out technical specifications, inquire directly or navigate to the Related Document section to download PDFs. They will guide you through the series, threads, weight, DIN criteria, and other essential characteristics.


Once you are ready to incorporate the nut into your systems, Fitsch specialists are at your service. Buy Parker hydraulic adapters online, choose the perfect nut type, and select the preferred finish. Precision engineering and lightning-fast delivery are on us.
