Senior PLC

Senior plc develops, manufactures, and markets high-technology components and integrated systems for major original equipment manufacturers across the global aerospace, defense, land vehicle, and power and energy sectors. The company is organized into two primary divisions: Aerospace and Flexonics. The Aerospace division provides specialized high-pressure and low-pressure engineered ducting systems, custom control bellows, diverse assemblies, and sensors. It also delivers precision-machined and fabricated engine components, fluid system conduits and control products, alongside accurately machined airframe parts and assemblies. Concurrently, the Flexonics division offers a range of products including exhaust gas recirculation (EGR) coolers, fuel blending and distribution systems, and flexible couplings. Its portfolio further extends to custom-designed expansion joints, dampeners and flow diverters, adaptable hose assemblies, control bellows, fuel cells, heat exchangers, and precision-engineered components. Initially incorporated in 1933, the company was known as Senior Engineering Group plc until its rebranding to Senior plc in 1999. It is headquartered in Rickmansworth, United Kingdom.
