Klüber Klübertemp YV 93-92
Sliding agent for valves, fittings and installations carrying oxygen under medium partial pressure
Application Klüber Klübertemp YV 93-92
Klübertemp YV 93-92 is used as a sliding agent for the lubrication of valves, fittings and installtions carrying gaseous and/or liquid oxygen for chemical plants and apparatus requiring high resistamce tp various gases (conclusion by analogy based on chemical composition). The wide service temperature range, in particular at low temperatures, underlines the universal application possibilities of this sliding agent. We recommend users conduct their tests using the complete component under conditions similar to series application. The product's high pressure-absorption capacity and consistent friction values over a wide temperature range ensure constant actuation forces. Test results show the product's usability for an O2 content > 21 % by vol. under the operating conditions specified in the product data section of this product information leaflet. Possible applications are: – Oxygen valves – Peripheral aggregates of chemical installations – Hose couplings, e.g. oxygen pipe connections, bolts, slideways, etc. – Assembly aid for most rubber-elastic materials and plastics – For the industrial handling, maintenance and care of oxygen components Behaviour towards metals, elastomers and plastics Klübertemp YV 93-92 is normally neutral towards metallic materials, plastics and elastomers within the given temperature range. Nevertheless, we recommend checking the compatibility of the sliding agent with materials in contact prior to the introduction of this product.
Performance, Features & Benefits of Klüber Klübertemp YV 93-92 are:
- Reliable operation of installations and components using gaseous oxygen due to medium oxygen pressure surge resistance (see product data); due to good compatibility with most materials used in this branch of industry; due to a wide service temperature range, in particular for low temperatures
- Also suitable for installations and components carrying liquid oxygen
- Each product batch is checked for its reactivity to oxygen

Product Description Klüber Klübertemp YV 93-92
Klübertemp YV 93-92 is a white sliding agent with good wetting ability based on perfluorinated polyether and solid lubricants. It offers medium oxygen pressure surge resistance and high resistance to a wide range of chemicals. To ensure continuous adherence to this high quality standard, Klübertemp YV 93-92 is manufactured in small series subject to strict hygiene requirements and each batch is inspected based on M 034-1 List of nonmetallic materials (213-075).

Application notes
All surfaces to be wetted must be thoroughly cleaned prior to product application. The friction / lubrication points of surfaces / components must be clean and bright (i.e. free from oil, grease, dirt particles or perspiration). We recommend cleaning the surfaces with clean white spirit and then Klüberalfa XZ 3-1, ensuring residue-free surfaces when dried. For valves and installations carrying oxygen, the application procedure must also be "oxygen clean" in order to attain a "ready for oxygen service" condition. For use at low temperatures, e.g. where components are in direct contact with liquid oxygen, experimental testing and approval by the component manufacturer is required since the design and power ratings, for example in actuator gears, may play a decisive role in this context. For optimised service life, please contact our service engineers. *Notes on the lower service temperature limit (see product data): The service temperature is defined on the basis of physical and mechanical-dynamic product characteristics. At very low temperature and pressure, however, where oxygen remains fluid, the product retains its stability in liquid oxygen tests. If the product is intended to be used below the lower service temperature limit, it has to be checked if reliable operation of the component is ensured under these conditions. In cases of doubt, application-specific tests would have to be performed, possibly in the complete component and under conditions similar to practice.
