Improvement Over Discontinued Product

Rheolube 374A, a new lithium soap, medium viscosity, synthetic hydrocarbon grease, not only meets the requirements of MIL-PRF 32014, it is a suitable replacement for Andok(R) 260, a long-life grease recently discontinued by ExxonMobil.

Rheolube 374A was developed by Nye Lubricants, Inc., at the request of Wright-Patterson Air Force Base, Nonstructural Materials Branch, to meet the general requirements of MIL-PRF-32014, a multipurpose grease for use in the -54(degree)C to +175(degree)C temperature range in aircraft and missile systems. Rheolube 374A is the only qualified product for this specification (Qualification Reference MLB-02-20, 1 July 2002, Air Force Materiel Command, Wright-Patterson AFB). It has been assigned several National Stock Numbers, including NSN 9150-01-499-6634 for a 35 lb. pail.

The formula for Rheolube 374A also enables it to serve as a replacement for Andok 260. Over the past year, some of Nye's customers had requested suitable replacements for Andok C and Andok B, the two other members of the popular family of bearing greases that ExxonMobil discontinued two years ago. Nye developed Rheolube 374C, an NLGI Grade 4 grease as a replacement for Andok C, and Rheolube 374B, an NLGI Grade 2 grease as a replacement for Andok B. Rheolube 374C and Rheolube 374B are both lithium-thickened, synthetic hydrocarbon greases. Like its counterparts, Rheolube 374A offers several functional improvements over the petroleum-based Andoks. For example, compared to Andok 260, Rheolube 374A performs at lower and higher temperatures, has a higher viscosity index and lower evaporation rates, affords better wear protection as measured by the Four-Ball Wear Test (ASTM D-2266), and resists water and saltwater washout.

Early Results Spectacular

Early customer reports, detailed on the company's website, report reductions in noise, torque required, and temperature, over the old grease. Technical specs, and a sample offer, are offered on the company's website.
