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! Flurocarbon 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. If you are looking for standard non FAA-PMA M83248 series o-rings, go to O-Rings and Gaskets. McFarlane also has complete fuel selector, fuel shut off valve, and fuel strainer seal kits with all required seals and gaskets. Go to Fuel Selector/Shut-Off Valve Seal Kits or Fuel Strainer Parts to find the kit for your aircraft. |
