Home / NSL PMA Sealants

NSL proudly supplies FAA approved, NSL PMA sealants. NSL PMA sealants are cost effective alternatives to PPG/PRC sealants, deemed a non-critical part by the FAA. They conform to the specification of the PPG/PRC sealant and are approved replacements for those products on a vast range of aircraft including major manufacturers like Boeing and Airbus. The list of eligible manufacturers can be found in the PMA supplement which is listed in the FAA’s PMA database and on each of our product pages. Read our introductory guide to PMA sealants to learn more about the part and the FAA’s approval process.
