Product Overview
The MCM83248 Series O-rings are fuel-proof FAA-PMA replacement O-rings. Only McFarlane has FAA approval to replace the old, less fuel resistant nitrile (MS series) and synthetic rubber (NAS series) O-rings with the latest fuel proof fluorocarbon O-rings. Fluorocarbon rubber is commonly known as Viton. It is an advanced rubber that has extremely good fuel and heat resistance and is ideally suited for aircraft fuel system applications.
Can also be used as Hydraulic and Oil Seals.
