AeroShell Grease 33

AeroShell Grease 33 is a General Purpose Corrosion Inhibiting Grease

AeroShell Grease 33 (ASG33) is universal airframe grease. ASG33 is effective on virtually all airframe components. AeroShell Grease 33 provides all-round protection in the harshest of conditions, from temperatures as low as -54°C through to scorching heat. All the while, AeroShell Grease 33 helps maintain mechanical stability, avoids water washout and protects your aircraft parts from corrosion caused by de-icing fluids. It often exceeds industry requirements and outperforms many AeroShell Grease 33 alternatives in laboratory tests – making it a trustworthy choice for facing the extreme conditions your aircraft will face.

  • Reduced costs through superior protection, longer grease life and simplified maintenance and inventories
  • Longer component life from superior corrosion and wear protection
  • Longer grease life through excellent mechanical stability and controlled oil separation
  • Peace of mind from a grease with more in-service hours than any grease in its class
Simpler and safer maintenance:
  • The logistics of stocking greases for varied aircraft applications can be complicated. With numerous products, it is easy for the wrong grease to be used. An unsuitable grease may fail to protect components adequately and may even be unsafe.
  • To simplify maintenance and reduce product-misapplication risk, Boeing created its BMS 3-33 specification. A grease meeting this standard would replace a range of greases, and extend component life and lubrication intervals.
  • Following a testing period by Boeing, AeroShell Grease 33 was the only product to meet all the requirements of the original BMS 3-33 specification. It can be used on all but 9 of the 359 grease application points on a Boeing 737. This greatly simplifies the maintenance of this and many other aircraft and enhances safety by reducing the risk of product misapplication
Protecting components from wear:

AeroShell greases can help to extend component life and reduce maintenance costs by preventing wear and corrosion. For example, in industry tests, AeroShell Grease 33 showed A smaller wear scar in a wear test than a MIL-PRF-81322G specification grease 4. No corrosion in saline solution, whereas a bearing with MILPRF-81322G-specification grease showed corrosion between the rollers and the race. Its partner, AeroShell Grease 64 (formerly AeroShell Grease 33MS) is designed to provide similar benefits for the protection of heavily loaded sliding surfaces such as the bogie pivot pins on landing gear assemblages. It contains 5% molybdenum disulphide for exceptional load-carrying and extreme-pressure performance.

Please Note:in some applications and subject to OEM approval, AeroShell Grease 58 may be an acceptable alternative.

Safety Precautions: Comply with all local safety, disposal and transportation regulations. Check the Safety Data Sheet (SDS) and label of the individual products carefully before using the products. SDS’s are available on request.
