Drinking water is the most sensitive substance we encounter in our daily lives. We take it for granted, yet it is also precious. That is precisely why every detail determines whether trust is built or lost. For this reason, wherever drinking water flows, materials, structures, and lubricants must meet the highest standards.
Berulub Sihaf 2-2 was developed specifically to meet this need. As a PFAS-free and allergen-free lubricant, it provides protection where the highest hygienic, technical, and material requirements converge. It ensures smooth movement, reliable seals, and consistently stable performance in fittings that come into direct contact with drinking water on a daily basis.
In single-handle faucets with ceramic seals and control discs, Berulub Sihaf 2-2 ensures smooth, long-lasting operation while protecting against wear. The lubricant adheres reliably, remains stable even with constant contact with water, and prevents friction, material fatigue, or deposits from impairing function.
At the same time, Berulub Sihaf 2-2 is gentle on the materials it comes into contact with. Delicate plastics such as PC, PMMA, and ABS are protected, as are elastomers and ceramic surfaces. This ensures safety in design, freedom in material selection, and reliability in operation. Perfect.
The focus here is particularly on what is not included. Berulub Sihaf 2-2 is free of PFAS and microplastics, contains no allergens as defined by applicable regulations, and does not contain any intentionally added substances containing MOSH or MOAH. It does not affect the smell or taste of the water and does not provide a breeding ground for microorganisms. As a result, it meets not only technical requirements but also health and social expectations for modern products in the drinking water sector.
The lubricant is also future-proof from a regulatory standpoint. International approvals and certifications confirm its suitability for use in drinking water applications and give both manufacturers and operators the confidence to rely on a solution that will stand the test of time, both today and tomorrow.
Berulub Sihaf 2-2 is therefore more than just a lubricant. It is considered a cornerstone of trust. For safe products. For technology that works quietly in the background and, precisely for that reason, offers decisive added value.
