Expanded Graphite Packing Ring

Expanded graphite packing ring:Expanded graphite packing ring is entangled in a row by expanded graphite paper and is compressed and molded in the mould. It boasts various excellent properties the good sealing materials possessed, and it is especially suitable for static sealing components in high temperature and high pressure conditions, whether being used alone or in combination with other filling materials. It can be used in almost all media except aqua regia and strong oxidizing acid. Scope of application: Maximum operating temperature: 450 °C (oxidizing atmosphere) 600 °C (non-oxidizing atmosphere) Maximum operating pressure: 6.3MPa (alone) 25.0MPa (combined) PH value: 0 - 14
