About JPB Système

JPB Système designs and manufactures patented self-locking devices that prevent bolts, nuts and fittings from loosening under vibration or temperature change, without lock-wire. Its products include the LULYLOK™ B-nut for gas, fluid and pneumatic connections, a self-locking borescope plug, and the BOLTRAKK bolt-tension monitoring system. The company also offers customised products, additive manufacturing (metal 3D printing) and KEYPROD, a plug-and-play production monitoring system based on IoT and AI.

Aerospace is the company's original market, and it lists aircraft industries, transport, defense, energy and amusement parks among its business areas. It states that 85% of its sales are international. Revenue comes from the sale of its patented and customised products; it names contracts with Safran and Rolls-Royce among its milestones.

JPB Système was founded in 1995 by Jean-Pierre Marc and Bernard Barre, and is headquartered in Montereau sur le Jard, France. Its main factory is in Villaroche (France), with a mirror plant in Rzeszów, Poland, and a sales office in Cincinnati, USA. The website gives a headcount of 200 employees and 15 international patents. Open positions include industrialisation, machining, assembly, dimensional control, purchasing and IT systems roles.

Product: Patented self-locking fasteners and fittings (LULYLOK™ B-nut, borescope plug, BOLTRAKK bolt-tension monitoring), with customised manufacturing.
