NSL proudly supplies FAA approved, NSL PMA silicones. NSL PMA silicones are high strength, acetoxy silicone RTV adhesive. They are non-critical parts and alternatives to GE and Dow Corning silicones. These silicones provide the same quality to you but at a lower cost. They conform to the specification of the GE and Dow Corning silicones 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.

We have the capability to provide custom packaging and sizing. All our orders are shipped with 8130s.
