Material
AVA45

Material Description
AVA45 performs exceptionally well in non-lubricated applications where operating temperatures are a major factor in the performance of the seal. AVA45 combines the strength and thermal conductivity of the bronze with the frictional properties of the Moly Disulfide for both cryogenic and high temperature air service. Wear tests performed by the US Navy for their high pressure non lube compressors showed AVA45 to have the best wear properties of all standard PTFE tested.
Recommended Applications: High Temperature Air Cryogenic Service
