Klüberbeta VR 67-3500 Special soft grease 25kg

Special soft grease for sanitary, beverage and heating valves and taps | N° 022224

Klüberbeta VR 67-3500 is a soft white adhesive silicone grease. The particular consistency and the use of special silicone oils ensure reliable operation over a wide temperature range for sanitary, beverage and heating valves and taps.

Klüberbeta VR 67-3500 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 Klüberbeta VR 67-3500 can contribute to increase reliability of your production processes. We nevertheless recommend conducting an additional risk analysis, e.g. HACCP.

• Temperature range: -40°C to +160°C 
• Volume: Can 1 kg
• Also available in: Bucket 25 kg

Benefits for your application

Prolonged service life of cartridges, valves and fittings due to

• Continuous wetting of the friction surfaces
• Compatibility with most standard elastomers and plastics
• Friction and wear reduction in most material combinations

Prevents stick-slip and provides balanced damping of operation

• Temperature has little effect on lubricating film thickness

Certified for use in drinking water and beverage taps

• According to BWGL-KTW (UBA-guideline) (German Environmental Agency), NSF/ANSI/CAN 61, WRAS, ACS, AS 4020
• Further certification available on request

NSF H1 registered supporting process reliability

Applications

• Klüberbeta VR 67-3500 is suitable for drinking water and beverage taps as well as in heating installations whenever complex friction geometries require a fluid grease distribution.
• Typical applications include the lubrication of ceramic discs, e.g. in single lever mixer taps, piston mixers, shower valves, thermostats, and similar components.
• Klüberbeta VR 67-3500 generally provides load-bearing lubricating films up to 2.5 N/mm² under normal operating conditions in the industry. Depending on the design, this value can also be exceeded.
• Due to its consistency, Klüberbeta VR 67-3500 is particularly suitable as assembly lubricant for seals, O rings and seal packings.
• It also reduces friction and wear in other components like plastic taps, packings and laboratory equipment.

Application notes

Klüberbeta VR 67-3500 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. Klüberbeta VR 67-3500 can be applied by means of spatula, brush, usual metering devices or the tampon printing method. Please observe the material safety data sheet.
