2, fluorine rubber (FKM): FKM is a high-level elastomer, its heat resistance, oil resistance, solvent resistance are very good, can withstand high pressure oxygen. However, when using FKM, you need to pay attention to its easy spontaneous combustion under high concentration of oxygen, so you need to master the correct installation method and use conditions.
3, graphite: graphite is a high-temperature stability and corrosion-resistant materials, can provide good sealing effect in high-pressure oxygen environment. However, graphite is also fragile, easy to wear and other problems, need to be selected and used according to specific circumstances. High-pressure oxygen valve is a special valve used to control the flow and pressure of oxygen, mainly used in industrial production, medical equipment and aerospace and other fields. Because oxygen has the characteristics of flammable and explosive, so the sealing of high pressure oxygen valve needs special attention, and it is very critical to choose the appropriate sealing material.
