NSL Aerospace — now part of Bron Companies — has been a trusted partner to airlines, MROs, and OEMs for more than 30 years. As an AS9100 & NADCAP-certified distributor and FAA-approved PMA manufacturer, we supply aerospace sealants, adhesives, and specialty chemicals that meet the highest industry standards. When standard OEM channels fall short, NSL delivers.
From FAA-approved PMA sealants to global distribution — NSL Aerospace delivers what aviation demands.
We develop and manufacture FAA-approved PMA alternatives to industry-standard aerospace sealants. Same specs. Better availability. Approved for Boeing, Airbus, Embraer, and more — at a fraction of the lead time.
We distribute and repackage a wide range of aerospace chemicals — sealants, adhesives, lubricants, and coatings — in the exact quantities and formats your operation requires. From Semkits to pints and quarts, we package to your spec.
With a global procurement network and strategic long-term partnerships, we source hard-to-find aerospace materials across chemicals, metals, tapes, and tooling. If it's on your spec sheet, we'll find it.
A "Parts Manufacturer Approval" (PMA) is a combined design and production approval granted by the FAA for aircraft modification and replacement articles.
It allows independent manufacturers to legally produce and sell replacement parts that function exactly like or better than the original equipment
