What Repack-S does

Repack-S is a French, privately-held industrial SME founded in 1997 and headquartered in Cuisery, Burgundy, that designs, manufactures and supplies custom-engineered sealing solutions and self-lubricated guiding systems for demanding industrial environments. Its product portfolio spans static seals, dynamic seals, rotary shaft seals, scrapers, and guide rings, complemented by a proprietary branded family — DANAFLEX®, DANAROTO®, DANAWING® (patented), DANAGLIDE®, DANACAP®, DANASTEP® HF, HPX®-Mono®, and the OSIS® on-site injection system (patented) — together with a proprietary REPKOT® high-load composite material used as an economic alternative to bronze bushings. Manufacturing capability covers 0.5mm to 2,450mm diameter components in-house, extending to 6,500mm / 90kg molded rubber seals via a co-manufacturing partner, in materials including PTFE, UHMW-PE, PU/TPU, PVDF, PEEK, POM and a wide range of elastomers compliant with FDA, USP Class VI and REACH.

The company sells exclusively through direct engineering-driven sales, with technical sales executives covering UK, Scandinavia, USA, Canada, Brazil, China, Russia and the Middle East, supplemented by participation in SIAE, Drinktec, Hannover Messe, Cibus Tec, Motorsport World Expo and Professional Motorsport. It serves six primary verticals — aerospace (AS9100 certified since June 2022, listed in OASIS), motorsport, bioscience & pharmaceutical, food/beverage/packaging, hydropower, and oil & gas — plus heavy-duty industrial applications (metal forming presses, extruders, offshore, dam actuators, high-speed train and seismic dampers, mining). Pricing is custom project-based with documented willingness to produce single-piece orders.

With ~30+ employees and over 30 years of accumulated sealing expertise, Repack-S monetizes primarily through one-off engineering projects and small-to-medium production runs. The company is led by President Christophe Rodriguez and operates without external investment, M&A activity, or public listing. The core economic engine is converting proprietary materials (REPKOT®) and patented seal architectures (DANAWING®, OSIS®) into high-margin, specification-locked component supply for mission-critical applications where failure costs — aerospace actuators, hydropower turbines up to 6,000mm, racing engines — are multiples of seal price.
