AeroShell Grease 33 – Industry Leading Universal Airframe Grease

Reduced Costs

By replacing multiple products, AeroShell Grease 33 can help to reduce costs by simplifying maintenance procedures and product inventories, and can improve safety by reducing the risk of product misapplication. It is trusted by leading airlines and has more in-service time than any other grease in its class.

It can be used on all but 9 of the 359 grease application points on a Boeing 737, thereby greatly simplifying the maintenance of this and many other aircraft. 


Pie charts comparing grease 33 and 64

AeroShell Grease 33 was the first and, for many years, the only grease to meet the original BMS 3-33 specification. 

Back then, Boeing challenged 20 manufacturers to formulate a grease to meet its original specification. The new product would cover the properties previously provided by 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.

"It remains the product to beat by offering superior corrosion and wear protection compared with other approved greases on the market."

Longer Lubricating Life

To protect components, a grease needs to maintain its mechanical stability to stay where it is needed. AeroShell Grease 33 has better mechanical stability compared with other currently approved products.

To lubricate effectively, a grease’s base oil needs to be released from the thickener in a slow, controlled manner. If the oil separation is too fast, the grease may become too hard to provide adequate protection. If the separation is too slow, the grease may fail to lubricate efficiently and allow excessive component wear. The oil separation of AeroShell Grease 33 is about 1.6 wt% better than the maximum allowed in the MIL-PRF-23827C specification.
