Improving Seal Efficiency with Lubricants

Rubber seals are essential components in the operation of pumps, compressors, engines, and other pressurised equipment. Seals are also required in weatherproofing applications, including automotive sunroofs.

In order to function optimally when in contact with harsh fluids or gases, rubber seals require high-quality lubrication.

Whether a seal is static or dynamic, our high-performance lubricants provide the barrier integrity necessary for superior performance. Our high-performance lubricants can also be matched to a seal’s operating temperature and chemical environment. This means seals made from any material, in any environment, can be optimised to work efficiently for specific use cases.

The global seals and gaskets market was estimated at a value of £50 billion in 2021, growing at a rate of 4.1% over the next decade. This growth is accounted for by the increasing use of advanced materials in manufacturing gaskets and seals for critical applications including aircraft manufacturing, medical equipment and chemical processing. This leaves manufacturers of seals to look for new, innovative lubricating solutions to improve efficiencies and reduce costs, gaining a competitive edge in this growing market.

Lubricate Rubber Seals with High-Performance Lubricants

Here at Antala, we provide Molykote and Krytox high-performance lubricants; oils and greases that offer exceedingly long life and outstanding properties for the superior lubrication of rubber seals. Other benefits of using Krytox and Molykote high-performance lubricants for seal lubricant applications include:

  • Ability to survive extreme temperatures and water washout
  • Fully retain their properties over the life of a seal – preventing seal damage or breakage
  • Non-damaging to plastic or elastomers – broad elastomeric compatibility
  • Non-corrosive to metals
  • Non-oxidising
  • Extended lubricant life due to low volatility and outgassing
  • Non-hazardous and non-toxic
  • Indefinite shelf life if unopened and stored in a clean, dry location
  • Minimal environmental footprint; no damage to the atmosphere or ozone layer
  • Both oils and greases are suitable for automated spray application
  • Resistance to acidic or caustic cleaners and disinfectants, steam, and moisture

As a result of these benefits, manufacturers of rubber seals can benefit from reduced maintenance and repair costs while improving their safety, efficiency and product quality.

Molykote 111 is a lubricant and sealant that can be used for the effective lubrication of rubber and plastic seals. It provides good resistance to most chemicals and excellent water resistance. This lubricant is ideal for outdoor installation equipment exposed to the action of water and severe environmental conditions. It prevents o-rings from sticking to metal and is resistant to weather conditions and water stripping. It can also be used on pressure connections, control valves and vacuum systems.

Krytox NRT 8906 is a high-performance grease which is resistant to high temperatures. It can be used for the lubrication of rubber seals, as well as valves, pumps, motors and bearings. It provides superior film-forming capabilities and non-reactive lubrication.

In addition to rubber seals, discover how our high-performance lubricants can be used in reducing thread failure, autoclave doors, valves and bearings.
