The ElringKlinger Group’s operating business is divided into four segments, as outlined below:

Original Equipment
Within the Original Equipment segment, ElringKlinger develops, manufactures, and sells products and assemblies destined for the automotive industry. They include lightweight components, thermal and acoustic shielding systems, cylinder-head and specialty gaskets, battery and fuel cell systems, and complete electric drive units. Supplied to the car and truck market, these products are used in engine, drivetrain, exhaust system, underbody, chassis, and vehicle body applications.

In the Aftermarket segment, ElringKlinger offers an extensive range of high-quality gaskets, gasket sets, and service parts for the professional repair of engines, transmissions, exhaust systems, and auxiliary units in cars and commercial vehicles. They are marketed under the “Elring – Das Original” brand. Business within the Aftermarket segment is transacted through a global network of wholesalers and major group purchasing organizations. Alongside Western and Eastern Europe, the key markets for this area of business in terms of revenue include the Middle East and North Africa. ElringKlinger has been expanding its sales activities in North America and China in recent years. 

Engineered Plastics
Within the Engineered Plastics segment, ElringKlinger develops, manufactures, and markets a wide range of customized products made from various high-performance plastics. Revenue is attributable primarily to sales within the mechanical engineering sector and the medical, chemical, and energy industries as well as the vehicle industry. ElringKlinger is pushing ahead with efforts to expand its business in this segment at an international level and also operates production sites in the United States and China. 


As from the 2020 financial year, the segment referred to as Other comprises the activities of the former Services and Industrial Parks segments. With a share of 0.3% of Group revenue, it is of subordinate importance. Services include the operation of state-of-the-art engine test benches and measuring equipment for tests on engines, transmissions, and exhaust systems. The segment's customer base includes both vehicle manufacturers and automotive suppliers. This segment also includes logistics services for aftermarket sales and the catering service of a Group subsidiary.

Original Equipment 79% Car, truck and engine manufacturers, automotive suppliers, non-automotive
Aftermarket 14% Independent aftermarket business
Engineered Plastics 7% Vehicle industry, mechanical engineering, medical technology
Other <1% Unspecified industries

The segments of the ElringKlinger Group are further divided into eight business divisions. The Original Equipment segment is subdivided into the following five divisions: Lightweighting/Elastomer Technology, Metal Forming & Assembly Technology, Metal Sealing Systems & Drivetrain Components, E-Mobility, and Exhaust Gas Purification. Each of the three remaining segments (Aftermarket, Engineered Plastics, and Other) also constitutes a separate division.

Lightweighting/Elastomer Technology
The portfolio of the Lightweighting/Elastomer Technology business unit encompasses thermoplastics for drivetrain, body, and underbody applications. Hybrid technology, i.e., the combination of different materials such as plastic and metal in one product and manufactured in a single tool sequence, also forms an integral part of operations in this business unit. A variety of manufacturing processes and numerous materials or material-specific innovations provide the basis for tailor-made solutions with high functional integration and/or weight savings. Due to the trend toward lightweight construction within the automotive industry, this business unit offers significant growth potential.

Metal Forming & Assembly Technology
The Metal Forming & Assembly Technology business unit develops and produces thermal, acoustic, and aerodynamic shielding systems. They handle a wide range of tasks relating to temperature and acoustic management in modern motor vehicles, in addition to contributing to an aerodynamic design of the vehicle underbody. For e-mobility applications, the systems may also include electromagnetic shielding functions. ElringKlinger offers customized shielding packages for the entire vehicle – from the engine to underbody and exhaust tract.

Metal Sealing Systems & Drivetrain Components
ElringKlinger created the new business unit Metal Sealing Systems & Drivetrain Components effective from October 1, 2020. Previously operating as independent business units, Cylinder-head Gaskets and Specialty Gaskets were transferred to this new unit. The product portfolio managed within this business unit includes a broad range of gaskets for various locations in the vehicle, including batteries and electric motors as well as transmission control plates and complex formed parts engineered from sheet metal. It also includes metallic cylinder-head gaskets as one of ElringKlinger's traditional fields of business.

The E-Mobility business unit offers the key technologies currently needed when it comes to drive system electrification: ElringKlinger can draw on many years of R&D expertise relating to battery and fuel cell technology and is already set up for series production. Intensive research and development activities and significant investments, e.g., in the construction of a technology center at the Dettingen/Erms site, have contributed to this in recent years. In 2020, ElringKlinger entered into several cooperation agreements in the field of fuel cell technology for the purpose of taking it to the next level, in addition to accelerating production and marketing. Furthermore, the E-Mobility portfolio includes complete electric drive units.  

Exhaust Gas Purification
Group activites within the Exhaust Gas Purification business unit are mainly restricted to the production of components on the basis of contract manufacturing.
