Continuing our series on Castrol Braycote greases, we are looking at Braycote 3214, a synthetic grease that works well in landing gear assemblies and with existing components, as well as in new installations.
Braycote 3214 plays nicely with other lithium-thickened greases in challenging conditions and in aircraft applications requiring water resistance, high load-carrying capacity, and a grease fully approved and qualified to the MIL-PRF-32014 standard.
Castrol Braycote 3214 is a multi-purpose, high-temperature, full-synthetic aircraft grease for demanding service where heat, humidity, speed, and water exposure can shorten grease life.
In military and commercial sustainment, that matters because MIL-PRF-32014 is the qualification framework for aircraft and missile grease used across a wide operating band, and Braycote 3214 is approved and qualified to that specification.
Within the broader Brayco/Braycote family, Braycote 3214 is a synthetic, lithium-thickened, water-resistant grease for aircraft mechanisms that need both corrosion protection and high-speed capability.

Braycote 3214 uses a medium-viscosity synthetic base oil with a lithium soap thickener.
Its operating range is -65F to 347F (-54C to 175C), matching the MIL-PRF-32014 temperature range for aircraft and missile systems.
The attached excerpts do not provide a complete commercial pack matrix by part number. The military specification defines qualification and procurement by the container type and capacity called out in the contract. In contrast, qualification samples include two one-pound containers, plus base oil and additive samples.
As with most industrial greases, this one causes skin sensitization, reproductive toxicity, and repeated-exposure target-organ warnings, and recommends gloves, protective clothing, eye protection, and adequate ventilation where needed.
The SDS also notes that high-pressure injection through the skin is a medical emergency, which is especially relevant when grease guns and pressurized dispensing tools are used in line maintenance or component shops.
Castrol lists a maximum recommended shelf life of 7 years from the date of manufacture when stored unopened under ambient conditions, and the SDS recommends storage in the original sealed container in a cool, dry, well-ventilated area away from heat and direct sunlight.
When procuring aviation-use lubricants, buyers must verify that the seller can provide traceability to a QPL for the qualified product.
This is largely subjective to the aircraft in question, since all aircraft have different maintenance cycles. Generally speaking, grease is a lubricant that needs to be renewed rather than replaced. Always check component-specific technical data in the aircraft maintenance manual or CMM, since the lubricant manufacturer does not determine this for any aircraft.

Our goal is customer satisfaction, and since we specialize in working with federal government and military customers, we set out to streamline this process as best we could. The GSA Schedule is the easiest way to do this: use the official U.S. government e-commerce website, GSA Advantage. We have nearly 1,000 items listed on GSA Advantage, including Castrol Braycote 3214 and many other common greases.
