BS Aflas O-Rings | OneMonroe

British Standard O-Rings are very similar to Standard O-Rings in the fact that they are both standardized imperically. The British Standard however, incorporates some extended sizes in the 1/4" nominal cross section group for an even broader application range. British Standard O-Rings serve a variety of industries including aerospace, paint, food, and chemical transport.

This elastomer is a copolymer of Tetrafluoroethylene (TFE) and propylene. Its chemical resistance is excellent across a wide range of aggressive media.For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart.
