What IDG-Dichtungstechnik does

IDG-Dichtungstechnik GmbH is a privately held German manufacturer of industrial sealing solutions, founded in 1971 and headquartered in Albershausen (Kirchheim unter Teck region). The company designs, develops, manufactures, and sells precision seals and construction elements to industrial customers across three vertical segments: Industry/Engineering (hydraulic and pneumatic sealing systems), Food Industry (hygiene-critical seals with CIP/SIP compatibility and metal-detectable materials), and Hydropower (turbine and control sealing components).

Its product portfolio spans static seals (precision O-rings, MANOY® back-up rings, encapsulated O-rings, XXL O-rings, X-rings, ManoyPerfluor® and PTFE O-rings), dynamic seals for hydraulic and pneumatic systems (piston, rod, shaft, and axial seals compliant with DIN ISO 7425-1/-2), bearings, wipers/scrapers, surface treatment services, dosing pistons, dairy coupling seals to DIN 11851, and a full Hydropower sub-line covering pivot pins, guide vanes, Pelton nozzles, Kaplan blades, and servo motors. Differentiation rests on three registered in-house material platforms — MANOY®, ManoyPerfluor® (perfluoroelastomer), and ManoyDetect® (metal-detectable) — combined with engineered-to-order "special constructions" for customer-specific requirements.

IDG operates a direct B2B sales model selling manufactured components to industrial buyers from a single German site via website contact forms, phone, email, catalogue requests, and a Quick Search product tool. Pricing is quote-based and not publicly disclosed. The company employs 51–100 people, holds no disclosed subsidiaries, has no parent company, and reports no funding rounds or M&A activity; it appears to operate as an independent, family-style specialty manufacturer with brand identity organized around the MANOY® family of trademarks.

Core offering

IDG-Dichtungstechnik GmbH designs, manufactures, and sells industrial sealing components and construction elements, including static seals (O-rings and back-up rings), dynamic seals (piston, rod, shaft, and axial seals), bearings, wipers/scrapers, and surface treatment services. The portfolio serves three vertical markets: industrial/engineering (hydraulic and pneumatic systems), food and beverage processing (CIP/SIP-capable hygiene seals with metal detectable materials), and hydropower generation (turbine, guide vane, and Pelton nozzle components). Manufacturing is based in Albershausen, Germany, with proprietary MANOY® material compounds developed in-house.

Product overview

IDG-Dichtungstechnik GmbH is a German manufacturer of industrial sealing solutions operating across three main sectors: Industry/Engineering (hydraulic and pneumatic sealing systems), Food Industry (hygiene-critical seals with CIP/SIP compatibility and metal-detectable materials), and Hydropower (specialized turbine components). The product portfolio centers on precision sealing technologies including O-rings (Precision, Encapsulated, XXL, X-ring, ManoyPerfluor®, PTFE variants), back-up rings (MANOY® brand), and dynamic seals (piston, rod, shaft, and axial seals) for hydraulic and pneumatic systems. The company also offers bearing solutions, wipers/scrapers, surface treatment services, and detectable material compounds (ManoyDetect®) for food safety applications. MANOY® material compounds represent the company's proprietary material development for complex specifications.
