Mobil Synturion™ 6

Mobil industrial , France

Supreme Performance Seal Oil, Barrier Fluid, Buffer Fluid

Product Description

Mobil Synturion™ 6 is a premium-quality, synthetic-base fluid specially formulated to meet the demanding lubrication and cooling requirements of mechanical seals --and to maximize seal life. The superb inherent properties of the polyalphaolefin synthetic base oil, enhanced by a proprietary additive package, are ideally suited to the special requirements of mechanical seal operation.


Features and Benefits



Advantages and Potential Benefits

Low viscosity, reducing internal friction and facilitating heat transfer

Efficient heat transfer from seal surfaces keeps seals cooler, extending life

Outstanding thermal and oxidative stability at high operating temperatures

Resistance to deposit formation, which can extend seal life

Longer oil life in seal circulation systems

Excellent lubricity and anti-wear protection

Reduces friction and can increase efficiency in sliding mechanisms such as seal faces, with potential for lower steady-state operating temperatures and longer seal life

High flash point

Safer operation in higher temperature applications

Reduced seal oil consumption

Compliance with FDA requirements for incidental food contact

Provides excellent performance in process equipment used in food industry, and food support industries

Inert and compatible with most process fluids

Provides consolidation opportunity, lubricating more process equipment with one fluid



Mobil Synturion 6 has been developed for the demanding application of barrier/buffer fluid for mechanical seals. The greatest enemies of mechanical seals are excessive surface temperatures and the resulting formation of hard deposits that further increase heat and friction. These factors can shorten seal life, potentially leading to product contamination and costly equipment downtime. Synturion 6 is specifically formulated to prevent premature seal failure. Its excellent thermal stability, low internal friction and heat transfer properties protect against excessive heat buildup and seal surfaces. Additionally, its proprietary additive package is designed to resist degradation and the subsequent formation of deposits.


Thermal and Oxidation Stability: In laboratory testing, Synturion 6 demonstrated significantly superior oxidation life and corrosion protection when compared with leading competitive products. The exceptional stability of Synturion 6 is particularly advantageous where hot process fluids can stress the lubricant, ensuring reliable performance at sustained high operating temperatures. In field tests, Synturion 6 has shown excellent resistance to reactive and corrosive process components such as H2S and acids.


Mobil Synturion 6 is NSF H-1 registered for food machinery lubrication and meets the requirements of FDA regulation 21CFR 178.3570 “Lubricants for Incidental Contact with Food".
