QPL-Listed Compounds
Parco is one of a few manufacturers approved to supply Qualified Products List (QPL) O-rings for aerospace and defense applications. QPL-listed compounds are compounds for which a manufacturer has received approval to sell to a certain specification. Each compound must complete rigorous independent laboratory testing to receive approval. The Aerospace and Defense industry buys product from only QPL-listed suppliers. The QPL list is maintained by Performance Review Institute (PRI) and the Wright-Patterson Air Force Base Material Laboratory.
