Klüber Unisilkon L 250 L Grease for valves and fittings 500g cartridge

Klüber UNISILKON L 250 L Special lubricating grease for drinking water, beverage and heating valves and fittingsUNISILKON L 250 L is a special lubricant based on silicone oil and PTFE with high thermal stability. UNISILKON L 250 L offers good penetration ability in small lubrication gaps and lube points of difficult access. Owing to its relatively high viscosity, adhesion is improved even in case of unfavourable geometries.UNISILKON L 250 L is resistant to cold and hot water, superheated steam up to approx. 130 °C as well as industrial cleaning agents and disinfectants. UNISILKON L 250 L is also resistant to pumpable foodstuffs and beverages like fruit juices, beer or milk products. UNISILKON L 250 L is not resistant toorganic solvents or strong acid and alkaline solutions.UNISILKON L 250 L is NSF H1 registered and therefore complies with FDA 21 CFR § 178.3570. The lubricant was developed for incidental contact with products and packaging materials in the food-processing, cosmetics, pharmaceutical or animal feed industries. The use of UNISILKON L 250 L can contribute to increase reliability of your production processes.We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.Temperature range: -45°C to +160°C Volume: 500gAlso available in: Cartridge 500g, Can750 g, Bucket 30kgBenefits for your applicationProven effective in valves and fittings as well as adjusting mechanisms in the drinking water, beverage, sanitary and heating sectorsCertified acc. to international standards for valves and fittings, e.g. DVGW-KTW, WRAS, ACS, AS 4020, NSF Standard 61 and NSF H1Long-term protection of seals and bearings owing to the lubricant’s good resistance to numerous media like disinfectants, cleaning agents, water, steamApplicationsUNISILKON L250L is used as lubricating and sealing grease for:domestic valves & fittings for drinking water, (e.g. ceramic discs and piston cartouches, thermo regulators). As the lubricant’s viscosity is rather independent of service temperatures, UNISILKON L250 L allows constant actuating forces within the whole cold/hot water range of e.g. single-lever mixer taps.valves and fittings of heating installations (e.g. thermoregulators, tap cocks, pressfit seals)UNISILKON L250 L has also proven effective as assembly aid for radial shaft seals and packings in contact with cold or hot water and steam.Application notesUNISILKON L 250 L is neutral towards most metals, thermoplastics and elastomers. Owing to the many different elastomer and plastic compositions their  compatibility should be checked prior to series applications. UNISILKON L 250 L can be applied by means of spatula, brush, usual metering devices or the tampon printing method.
