Aerospace Standard AS3209 Series AMS 7276 "O-Ring" Packing, Preformed
For a reliable seal, choose Aerospace Standard AS3209 O-Ring Packings from SkyGeek. The preformed O-rings are designed for use in high-temperature applications. They are resistant to most aviation fluids and are slightly flexible to maintain a perfect seal even when vibrated, heated or cooled. The O-rings are made with AMS7276 Duro Fluorocarbon 75 (FKM) rubber (70-80 durometer) and are well-suited to the demanding environments found in aircraft engines and systems. They can withstand temperatures as high as 400 degrees Fahrenheit without failing. These O-rings are harder and more durable than typical O-rings, making them more able to resist compression in high-stress applications.
