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. EP is also known as: Eythylene Propylene, EPR, EPDM, EPT, E.

EP is an elastomer which is characterized by wide range of applications and good chemical resistance. Ethylene propylene compounds have good resistance to detergents, alkalis, mild acids, greases, silicone oils, and alcohols.For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart.
