The right connection with hydraulic adapters from hansa‑flex

Adapters are required when hydraulic components with different connection types need to be reliably joined in mobile or industrial hydraulics. Adapters create a reliable, sealed transition between different connector types and enable the cost-effective adaptation of hydraulic components of different designs or from different manufacturers. HANSA‑FLEX supplies a wide range of adapters. These allow adaptation of any commercially available connector, including inch and metric thread types. In addition to connection types such as JIC (37° ISO 8434-2), ORFS (flat seal ISO 8434-3), BSP (60° ISO 8434-6/BS 5200) and NPT/F (SAE J514), HANSA‑FLEX also offers special types including 45° SAE connections.

Hydraulic connectors such as adapters find use in challenging applications and are exposed to extreme loads including, for example, oscillations and vibrations. Therefore all HANSA‑FLEX products are manufactured to the highest quality standards. As part of our quality assurance system, we carry out extensive testing and thus ensure that adapters can fulfil their role reliably. All adapters are available in steel with a zinc-nickel surface coating as standard. This guarantees high corrosion resistance to red rust of up to 1,500 h. On request, these adapters are also available in other materials such as stainless steel for maximum service life, even under the harshest conditions of use.

HANSA‑FLEX offers you not only a wide range of high-quality hydraulic adapters but also extensive technical advice [Link to contact details] about adapting your hydraulic systems. We take care to ensure that adapters are not only mechanically suitable but also reliably fulfil their intended function. With this in mind, our experienced fluid technology experts check through your engineering drawings and produce the precise technical solution that most efficiently covers your requirements. Whether you want to connect European and Asian systems, use a combination of different adapters or need to develop a special solution, no technical challenge is too great for us.

The seal of the adapters with the NPT thread commonly seen on the US-American market is achieved by wrapping the external threads with Teflon tape before installation to provide the maximum effective seal between the flanks. The NPT/F adapters have a 60° thread angle.

SAE adapters have cylindrical cone connections with a 45° sealing surface and an O-ring at the sealing collar. SAE adapters with an external thread on the other hand make a metallic seal.

The JIS thread, which was originally used mainly in Asia, has sealing flank surfaces inclined at 30° (thread angle 60°) and is designed similar to the 37° JIC connection (UNF thread).
