A 37 GraphoFlon
Braided from Expanded Graphite Tape Reinforced with Inconel Matrix and special PTFE impregnation
Characteristics
- No slip stick effect
- High cross section density
- High temperature resistant to minimize emissions
- Non hardening, good reset capability
- Coefficient of thermal expansion similar to steel
- Easy to cut, install and disassemble
- Low coefficient of friction minimizes the adjustment force in valves
- Recommended as die formed rings
- For valve applications rings should be approx. 25 - 30 % compressed at installation
