The non-metallic flat gaskets are the most typical ones from the family of flat static gaskets. They are used in a large number by various industries and in a a variety of applications. The soft gaskets are made of asbestos, non-asbestos, graphite, PTFE, mica, aramide and rubber sealing materials. Standard and nonstandard gasket design are available. Non-standard means gaskets of optional shapes and dimensions according to customer's design or sample.
| Compressed Jointing Gasket | Basis | Temperature ( °C ) | Pressure (Bar) | Application and Properties |
| RS7-A Asbestos Joiting Gasket | Asbestos fibres, synthenic elastomers, and inorganic fillers, nature rubber, etc. | Peak 200~550, Continuous 150~500 | 20~120 | For general use, good resistance to water, gases, oils, fuels |
| RS7-O Oil-resistant Asbestos Jointing Gasket | Asbestos fibres, synthenic elastomers, and inorganic fillers, nature rubber, oil-resistant rubber, mineral fibres, etc. | Peak 200~500, Continuous 150~450 | 20~140 | Good dynamic resistance for high loading(gas, oils, fuels). The rmal properties and good steam resistance economical quality for wide field of application. |
| RS7-N Non Asbestos Jointing Gasket | Aramid fibres, NBR, Nature rubber, etc. | Peak 200~450, Continuous 150~400 | 20~70 | Good thermal properties and excellent torque retention food industry and good resistance to water,gases. |

( Temperature and pressure represent maximum values and should not be used simultaneously. They are given only as guidance, since they depend not only on the type of gasket material but also on the assembly conditions lery important factors are thickness of material, nature of service medium, type of flange surface stress steam application requres special considerations.)
