Rota-Tech have wide range of O-Rings for many different applications. Designed to operate in the most extreme conditions.O-Rings are mostly use as a static seals in-between flanges or joint sealing and as primary sealing in mechanical seals and rotary unions. Rota-Tech also offers O-rings in advanced materials such as Viton™, EPDM, Nitrile and Teflon®.
An O-Ring is a mechanical gasket in round shaped used for packing & sealing, it is designed in such a way that it can fit in a groove and be compressed to give better sealing qualities.O-Rings are the most preferred sealing component because of the low cost, ease to make & simple mounting requirements.They are manufactured through a process known as moulding. O-Rings are available in various sizes the most common of them being AS568, BS & JIS2401 to name a few. The O-Ring size constitutes of two main dimensions: Inner Diameter (ID) & Cross Section (CS).With the right selection of material an O-Ring can be used in a varied media such as: Gas, Fuel, Chemical, Water, Lubricants Etc.O-Rings in all above material can be produced in regular hardness ( 70 / 75 / 90 ) Shore A.
Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range ofproducts for applications excluded to other materials.It is also known by the common trade name Teflon®. Teflon® is a registered trademark of DuPont and is used in relation to products manufactured with Dupont's fluoropolymer resins.It can also be machined or moulded into most any shape like O-Rings.
PTFE encapsulated O-Rings are designed to combine the sealing properties of the rubber O-ring with the chemical resistance of Teflon® PTFE. They are generally manufactured from Viton® or silicone rubber and are coated in a thin moulded layer of Teflon FEP or PFA. FEP encapsulated O-rings are our most common and are resistant to solvents and chemicals. They have a low coefficient of friction. PTFE encapsulated O-rings also have a good elastomeric memory. We can also supply rigid Teflon® PTFE O-rings which have a high compression set.
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is also known by the common trade name Teflon®. Teflon® is a registered trademark of DuPont and is used in relation to products manufactured with Dupont's fluoropolymer resins.PTFE can be modified for use as a gasketing material with strong chemical resistance properties. It can also be machined or molded into most any shape.
We specialize in various Teflon® Machined component like PTFE O- Rings, PTFE-Gaskets, PTFE-Bellows, PTFE-Packing,Teflon Bellow Seals ,Packing, Bellow and many more etc.
