Vactra Named and Double Lettered Series

Mobil industrial , United States

Circulating Oils

Product Description

Mobil Vactra Named and Double Lettered Series Oils are high performance general purpose lubricants intended for non-critical industrial applications where lubricant is supplied intermittently such as in all-loss systems, or where contamination and leakage are unavoidable. In such service, they offer an economic advantage over premium quality lubricants for plain and rolling element bearings in both reservoir and all loss systems, in gear applications and in hydraulic systems that do not require high quality anti-wear products.

Oils are formulated from high quality base stocks and additives, which provide resistance to oxidation and thermal degradation, and protection against rust and corrosion. Mobil Vactra Named and Double Lettered Series are the oils of choice for many operators world-wide requiring economical lubricants, which can meet a wide range of industrial applications.

Features and Benefits

Mobil Vactra Named and Double Lettered and Double Lettered Oils offer a variety of benefits that can contribute to lower operating and maintenance costs. They offer the following benefits:

FeaturesAdvantages and Potential Benefits
Very good thermal/oxidative and chemical stabilityHelps reduce deposits and filter fouling
Excellent rust and corrosion protectionClean system and long filter life and reduced maintenance
Good resistance to foamingAvoids pump cavitation and increases circulation efficiency
Wide range of applicationReduced inventory; reduced risk of mis-application


The Mobil Vactra Named and Double Lettered and Double Lettered Oils are general-purpose lubricants recommended for non-critical industrial applications where lubricant is applied intermittently such as in all loss systems, or where contamination and leakage are unavoidable. They provide excellent lubrication of plain and antifriction bearings. They are also recommended for moderate duty circulation and hydraulic systems where high leakage rates necessitate frequent makeup. The products should not be used where the bulk oil temperatures exceed 66ºC. Specific application areas include:

  • Moderate duty industrial gear applications.
  • Circulating systems not requiring anti-wear protection
  • Low to moderate severity paper machine applications.
  • Non-critical machine tool applications, many air compressor applications and other plain- and antifriction- bearing applications.
