CLESSE FRANCE

What CLESSE FRANCE does

CLESSE FRANCE is a French private industrial equipment manufacturer specializing in gas pressure regulation and safety hardware for LPG (propane/butane) and natural gas applications. Its product portfolio spans regulators (e.g., NOVEXI 100, BP3, DSI/CSR495), automatic changeover valves (CompacTR900, 2175C/T, 175B, 175CS/126), integrated safety valves (ROAI), flexible connectors and piping (FlexiGaz, Clessinox, FlexiKIT/FlexiPIPE), and natural gas network components (B6N, B10N). Several SKUs are explicitly engineered to satisfy the French arrêté du 23 février 2018 and the post-July 1, 2024 requirement for inlet pressure below 50 mbar with integrated safety shut-off on new domestic LPG installations.

The company operates a multi-brand architecture (CLESSE, NOVACOMET, Compact, FlexiGaz, Clessinox, FlexiKIT) with worldwide reach but primary concentration in France, where it sells exclusively through B2B specialist gas and plumbing wholesalers (Tereva, CCL, Prolians, Richardson, ebatpro, sisca, Desenfans, Sider, Sodexgaz, Sodigis). Revenue is generated through hardware sales to installers, distributors, and end users in residential, professional/industrial, and camping/outdoor-hospitality (HPA) segments. Commercial activity is supplemented by trade-show presence (Interclima, HPA season), technical documentation, and installer training.

In October 2025, CLESSE acquired Groupe WEBA, a Polish manufacturer of modular gas connection systems based in Poznań, extending the group's European manufacturing footprint and product portfolio. The company also offers the Compacti telemetry solution for remote gas-cylinder management, representing the only connected/IoT-enabled element of an otherwise hardware-centric catalog.
