    kluberbeta vr 87-883

    Klüberbeta VR 87-883 is a speciality lubricant based on silicone oil and contains light-coloured solid lubricants. It offers high thermal stability in the tribo-system, even under the influence of highly varied ambient conditions.

    Klüberbeta VR 87-883 offers good adhesion to various materials and their surfaces. While even friction points that are hard to access or narrow lubrication gaps are reliably wetted, the lubricant does not tend to flow off where the component geometry is unfavourable, e.g. in vertical arrangements or moving friction points.

    • Klüberbeta VR 87-883 offers versatile uses as a design element or assembly aid.
    • The product is used as lubricant, sliding and sealing agent e.g. in gas equipment of all categories including the additional fittings contained in them or intended to be fitted in them which can come into contact with fuel gases as defined in EN 377. Such fittings include ball, taper plug and other valves in cooking and heating installations, etc. (in copper and copper alloy material pairings as well as in those of aluminium/brass or aluminium/aluminium) that are used with fuel gases or gas mixtures such as natural or town gas as well as propane and butane as specified in DVGW worksheet G260.
    • Furthermore, Klüberbeta VR 87-883 is used wherever improved sliding performance, prevention of stick-slip and a reduction of abrasion and wear are desirable, e.g. in ceramic discs and piston cartouches, valves and fittings in heating applications (e.g. thermostatic valves), plastic valves, also when exposed to cold or hot water or steam up to 130 °C.
    • Further possible applications are friction points in the beverage, food-processing, cosmetics, pharmaceutical and animal feed industries, as a pressing-in or removal aid (e.g. for O rings, sleeves, etc.) or as a sliding and sealing agent for ground joints or valves in laboratory apparatus (e.g. in the chemical industry). In pneumatics, the product may be used for the initial and for-life lubrication of cylinders and valves and as an assembly aid e.g. for radial shaft seals or sealing packings, also in combination with cold, warm and hot water or many other chemical substances.
    • Klüberbeta VR 87-883 has low or no resistance to most organic solvents as well as strong acidic and alkaline solutions. Resistance to acidic and alkaline solutions with a concentration up to 10 % and a temperature up to 90 °C, however, is good.
    • Klüberbeta VR 87-883 is NSF H1 registered and therefore complies with FDA 21 CFR § 178.3570. The use of this lubricant contributes to increased reliability of your production processes. Nevertheless it is recommended to conduct an additional risk analysis, e.g. HACCP.

    Extended component service life due to

    • High thermal stability and very good low-temperature behaviour
    • neutral behaviour towards elastomers, plastics and metals
    • good resistance to media and sealing effect e.g. towards disinfectants and cleaning agents
    • very good resistance to both cold and hot water

    Operational smoothness and prevention of stick-slip due to

    • very low temperature dependence of lubricant film
    • very good and durable wetting of friction points
    • reduced friction and wear in a multitude of material combinations

    Certified acc. to globally leading standards for lubricants used for valves and fittings, e.g. guideline of the German Environmental Agency (UBA) BWGL-KTW, NSF/ANSI/CAN 61, WRAS, ACS, AS4020 and NSF H1 (further standards on request) and DIN-DVGWtype examination certificate acc. to DIN EN 377 class E (…160 °C) as lubricant for use in equipment  and actuators for fuel gases
