The portfolio is completed by components for shutting-off, regulating, throttling and measuring fluid media. For more than 50 years, the companies of STAUFF Group have been developing, manufacturing and distributing pipework equipment and hydraulic components for mechanical and plant engineering and for service and industrial maintenance. In addition to mobile and industrial hydraulic machinery, typical applications also include commercial and special purpose vehicles, rail transportation and energy technology. Likewise, STAUFF products are used in marine, oil and gas applications and in the process, food and chemical industries. The overall range currently includes about 50000 standard products as well as numerous special and system solutions according to customer’s specifications or based on our in-house development. All STAUFF products Undergo relevant testing in accordance with international regulations and are governed by the high standards of the in-house quality management system.

8 www.stauff.com/5/en/#8 Introduction Catalogue 5 § Edition 03/2024 STAUFF Quick Release Couplings STAUFF couplings have proven their value for many years in practical use in hydraulic systems. The excellent quality of the couplings is the result of continual product improvement in which the experiences of users have been taken into consideration, as well. Our high production standards, combined with our quality management system certified in accordance with EN ISO 9001, assures the quality of our products. For the technical specifications of the individual couplings please refer to the following pages of the catalog. Housing material Steel according to EN 10277: Couplings Series FF, FC, HP-10, IA, IB, ID, BP, HUS, PS, RK/RH, FG, HH, HI, HT and MK with Zinc-Nickel coating, Zinc-Plating and Thick-Film-Passivation (Chrome III) Seals NBR (Buna-N®), PTFE ISO 3601 Operating temperature - 25 °C ... + 100 °C / -13° F ... +212° F withNBR (Buna-N®), PTFE - 25 °C ... + 200 °C / -13° F ... +392° F with FKM (Viton®) Please contact STAUFF to require other combinations of materials. The operating pressures specified in our catalog relate to the strength of the housing components. Standardized connector shapes may have other rated pressures, which cannot automatically be applied to the particular coupling type. Any remodeling and modification of the couplings are prohibited. By any maintenance of our couplings it’s necessary to use original STAUFF parts. In case of using of no original parts or disassembling of the couplings the warranty will be expire. The STAUFF hydraulic couplings don’t have the 94/7/EG guidance for the using in explosive field. The couplings don’t have an own ignition source which could be a reason of inflame.
