The portfolio is completed by components for shutting-off, regulating, throttling and measuring fluid media. In order to perfectly match each other, STAUFF Line products are designed and offered on a high, uniform level of quality. A large proportion of the range made from steel comes as standard with the premium STAUFF Zinc/Nickel surface coating, which is also optionally available for many of the other components. This coating offers the most reliable surface protection far beyond the previous market standards – even after transport, handling and assembly of the components – and meets all current legal requirements. If desired, Original Equipment Manufacturers can be supported with value-added services, from technical consultation to pre-assembly, assembly and kitting as well as logistics services : § Support with the selection of suitable standard components and ordering options; provision of customised solutions according to customer’s specifications or based on our in-house development – from prototyping to large scale production § Analysis and optimizationof existing and design and developments of new systems aimed at increasing the efficiency and performance of machines and equipment and creating value for customers by reducing the total cost § Pre-assembly, assembly and kitting of individual components to customer-specific system modules § Individually coordinatedprocurement solutions (e.g. web shop and electronic data interchange) and supply models (e.g. from warehousing of customised components to Kanban logistics and just-in-time delivery of pre-fabricated system modules to the assembly lines of the customers) aimed at optimising material flows 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. Furthermore, many items have received certifications and approvals from various international institutes, organisations and authorities who have independently confirmed the quality and performance of the products. Wholly-owned manufacturing, sales and service facilities in 18 countries and a tight global network of authorised distribution partners ensure high presence and service paired with a maximum of availability.

7 www.stauff.com/7/en/#7 Catalogue 7 § Edition 06/2023 Introduction Aligned with the needs of the market, the product groups § STAUFF Test § STAUFF Diagtronics § STAUFF Filtration Technology § STAUFF Hydraulic Accessories include a comprehensive range of analogue and digital measuring equipment and devices, filtration systems and replacement filter elements as well as accessories for the construction of tanks, reservoirs, power packs and gear boxes in mobile and industrial hydraulics. The offer is completed by relevant value-added services: § Support with the selection of suitable components and ordering options; provision of customised solutions according to customer’s specifications or based on our in-house development – from prototyping to large scale production § Analysis of existing hydraulic circuits aimed at filtration systems, tank components and monitoring devices that perfectly match to the specific requirements, and developing integrated concepts to increase the efficiency and performance of machines and equipment § Individually coordinatedprocurement solutions and supply models

8 www.stauff.com/7/en/#8 Catalogue 7 § Edition 06/2023 Introduction STAUFF Test Test couplings from the STAUFF Test product range are already planned in suitable positions in the hydraulic system during the design phase of a machine, or added at a later stage in the course of retrofitting or upgrading. They allow machine operators and maintenance personnel to easily and safely connect analogue and digital measuring and display devices for the temporary testing or continuous monitoring of system pressure and other factors. If required, they also allow venting of the system as well as collecting representative fluid samples, e.g. for analysing the degree of contamination of the fluid. This type of connection requires no tools and can also be carried out during operation under full system pressure up to 630 bar / 9135 PSI (depending on the type of coupling). The check valve (ball or poppet valve) integrated into the test coupling opens only after connection of the measuring and display device with suitable adapters or test hoses, which complete the product range. This guarantees safe sealing of the connection without any risks of leakages or fluid escaping from the system. During production, STAUFF test couplings are not crimped after insertion of the internal valve components and seals but rather closed with a threaded nipple in a fully automated process, which secures the proper functioning of the couplings under permanent loads. The vibration protection feature, which prevents self-loosening of the protective metal cap caused by vibrations in the system, is another competitive advantage. For the finishing of the test coupling range in carbon steel, STAUFF relies on the STAUFF Zinc/Nickel surface coating which has proven successful for many years. It provides reliable surface protection – even after transport, handling and assembly – and meets all current legal requirements. Versions in stainless steel V2A and V4A are generally available from stock. Alternative materials and surfaces are available on request. For selected types and series, independent certificates and approvals can be provided: § Military approval for use as gas filling valves for nitrogen accumulators by the German Bundeswehr (Wehrtechnische Dienststelle für Pionier- und Truppengerät) § DVGW registration as test points for gas pressure control systems, issued by the German Technical and Scientific Association for Gas and Water

9 www.stauff.com/7/en/#9 Catalogue 7 § Edition 06/2023 Introduction § Appealing colour scheme with a bright semi-gloss surface finish – comparable to Stainless Steel § Significantly reduced tendency to corrosion by contact with other metals (such as Aluminium and Stainless Steel) § Improved abrasion resistance due to the ductility / plastic deformability of the coating § Little to no risk of triggering allergies – nickel release is down to only a fraction of the statutory limits relating to objects which come into direct and prolonged contact with the skin (independent results of the reference test method according DIN EN 1811 are available on request) § Good paint adhesion properties § Resistance against all commonly used hydraulic media STAUFF Zinc/Nickel Coating Layers Sealing Passivation Zinc/Nickel Steel § At least 1200 hours resistance to red rust / base metal corrosion under practical conditions in the salt-spray chamber according to DIN EN ISO 9227 § White rust occurs only by way of a slight grey haze § Surpassing the requirements of the corrosion protection class K5 as defined by the VDMA, the German Engineering Association (360 hours resistance to white rust / 720 hours resistance to red rust) § Free of hexavalent chrome Cr(VI) § ELV compliant according to 2000/53/EC (End of Life Vehicles Directive) § REACH compliant according to 1907/2006/EC (Registration, Evaluation, Authorisation and Restriction of Chemicals) § RoHS compliant according to 2002/95/EC (Restrictions of the Use of Hazardous Substances) With at least 1200 hours resistance against red rust, the STAUFF Zinc/Nickel surface coating offers excellent surface protection – even after transport, handling and assembly. This was confirmed by testing in the salt-spray chamber according to DIN EN ISO 9227. Users across all industries and applications benefit from sophisticated technology, which has been developed for and used by the very demanding automotive industry for many years now and that is already the proven standard for a large proportion of STAUFF components since 2007.
