Key Features
Graphite–PTFE Composite Structure: Combines sealing flexibility with smooth operating characteristics.
Excellent Sliding Capability: Supports lower friction during continuous shaft movement.
High Thermal Consistency: Maintains stable sealing performance under changing temperatures.
Strong Chemical Adaptability: Suitable for aggressive fluids and industrial media exposure.
Controlled Leakage Performance: Helps achieve efficient sealing in dynamic equipment.
Long-Term Operational Stability: Contributes to reduced maintenance and dependable service life.
Applications
For use in pumps, valves, reciprocating and rotating shafts, mixers and agitators. Especially designed for services involving surface speeds and temperature higher than those normally specified for pure PTFE packings.
Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents. It is also against water, steam, petroleum derivatives, vegetable oil and solvents.
