Discontinuation of AeroShell Fluid 602 and Fluid 5M-A

Our supply partner AeroShell have advised us of two products they will no longer be manufacturing due to a reduction in demand. Some stock still remains of these products within our supply chain, but once this stock has been exhausted, no further batches will be produced. 

AeroShell Fluid 602

Aeroshell 602 drum

Most widely used as a cooling fluid for aircraft avionic systems, whose benefits include lower initial cost, longer fluid life, lower weight and lower toxicity when compared with other types of avionic system coolants. A synthetic hydrocarbon coolant fluid for aircraft electronics, approved to MIL-PRF-87252E and NATO Code S-1748

AeroShell Fluid 5M-A

Aeroshell fluid 5-ma drum

A highly refined, medium viscosity mineral oil containing an extreme pressure additive as well as additives to provide good oxidation and corrosion protection. This product is approved to MIL-PRF-6086F Medium Grade and DEF STAN 91-112 Grade M as well as Joint Services Designation OEP-70 and NATO Code O-155. 

While there are no alternatives to these fluids from the current AeroShell portfolio, Silmid have been able to identify products approved to the same specifications that may prove to be a possible alternative upon customer review:
