La Cornue is regarded as the ‘crème de la crème’ of domestic stoves. Exceptionally high build quality is vital to this brand, and Loctite is playing its part by sealing gas fittings and locking threaded assemblies with utmost reliability.

Loctite engineering adhesives used in premium domestic stovesSince 1908 this prestigious family business has produced generations of elegant stoves for cooking enthusiasts. They integrate technological innovation with unique design and each product is hand built to customer specification.

The company uses several Loctite engineering adhesives in the process. Alain Savignat, Production Manager at La Cornue, explains: “What we expect from these products is absolute reliability, especially for the gas fittings. But Henkel provides more than just Loctite products. The company helps us develop new processes for the future too.”

Every year, La Cornue seals around 400m of pipes and 1600 connections. For assembling and sealing the gas connections it uses Loctite 577, a liquid medium-strength pipe-thread sealant. It reliably prevents connections from working themselves loose and stops any leakages caused by vibrations or impact. It also allows fine adjustments to be made during assembly before curing in anaerobic conditions.

This single component product is clean and easy to apply and does not creep, shrink or block systems. Loctite 577 has DVGW approval and can be used on pipe fittings up to 3”. It provides many performance benefits over solvent-based sealing compounds that shrink during cure and PTFE tape whose lubricants allow fittings to loosen.

This sealant is also a superior alternative to traditional hemp and paste that is messy to assemble, requires expert handling and frequently requires re-work to achieve a 100 per cent seal.

Another product that is widely employed at La Cornue is the Loctite 243 thread locker. The elegant enamel surfaces that are a feature of the stoves are prone to damage if a screw or other component is over-tensioned. This proven Loctite product allows careful assembly and a secure fastening.

Loctite thread locking and thread sealing adhesives are widely used across industry and available in multiple variants to suit the task. The needs of many of these applications can now also be met by the new Health and Safety options within both ranges. The Loctite 2400 and 2700 thread locking adhesives and the Loctite 5400 thread sealant are free from all hazard labelling. For further details, visit
