Special lubricating grease for drinking water, beverage and heating valves and fittings.

UNISILKON 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 to
organic 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.

Benefits for your application:
  • Proven effective in valves and fittings as well as adjusting mechanisms in the drinking water, beverage, sanitary and heating sectors
  • Certified acc. to international standards for valves and fittings, e.g. DVGW-KTW, WRAS, ACS, AS 4020, NSF Standard 61 and NSF H1
  • Long-term protection of seals and bearings owing to the lubricant’s good resistance to numerous media like disinfectants, cleaning agents, water, steam

Application:
UNISILKON L 250 L 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 L 250 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 L 250 L has also proven effective as assembly aid for radial shaft seals and packings in contact with cold or hot water and steam.

Application notes:
UNISILKON 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. Please observe the material safety data sheet.
