PTFE O Rings
Simply Bearings is a market-leading supplier of replacement PTFE O rings for a huge variety of industrial equipment. Our modern warehouse is stocked with a wide selection of differently sized and rated O rings - a selection that is so large that we are confident that we can provide you with the precise O ring to meet any of your requirements.
O rings are perhaps the most widely used and certainly the simplest form of seal, which is unsurprising given that they are largely inexpensive, reliable and easy to mount. They are found everywhere from pumps, engines and gearboxes to SCUBA diving gear and NASA's space shuttles. O rings can be used as shaft seals, enabling both linear and rotary movement in dynamic applications - for example, rotating pump shafts and hydraulic cylinder pistons - but it can also be used in static applications as face-to-face seals.
O rings demonstrate a very high degree of chemical resistance. They can safely seal tens of thousands of PSI. Operating temperatures extend from -30c to +120c, but specific O rings have different ratings.
PTFE, a form of thermoplastic polymer, is characterised by a slippery surface, high melting point and resistance to a wide range of chemicals.
