Series HS (Carbon Steel)

The HS series screw couplings from STAUFF have been specially developed for heavy-duty applications in high-pressure and high-impulse hydraulics. They consist of a coupling sleeve with external thread and a coupling plug with screw sleeve and are suitable for the secure connection of hydraulic lines up to DN 38 (1-1/2"). Thanks to their robust design and particularly high operating and burst pressures, the couplings are ideally suited for use in construction machinery and other demanding hydraulic applications.

The HS series screw couplings are available in several nominal sizes and therefore cover a wide range of hydraulic applications. The sizes available are DN 6, DN 10, DN 12, DN 16, DN 19, DN 25 and DN 38 (corresponds to 1/4" to 1-1/2"). This means that both compact lines and large-volume systems can be connected safely and reliably.

All variants fulfil the ISO 14541 standard and are therefore interchangeable with commercially available screw couplings of a comparable design. Depending on the application, the couplings can also be coupled with tools under residual pressure (up to 33 % of the operating pressure) - a plus in terms of flexibility during installation and maintenance.

The HS series combines maximum robustness with practical operation and safety:

• Secure connection even under extreme operating conditions

• Vibration-resistant and suitable for high pressure peaks

• Long-lasting corrosion protection thanks to thick-film passivated surface (chrome III)

• Interchangeability to ISO 14541 (DN 6.3 to 19) and DN 25 and 38 to market standard

STAUFF HS series screw couplings comply with the ISO 14541 standard and are therefore easily interchangeable with commercially available screw couplings of a comparable design.
