Graphite Polished Carbon Segment Seal Ring 3 mm up to 700 mm

Carbon-segment seal rings—also called segmented carbon rings—are composed of high-purity carbon graphite, often reinforced with resins or metals. Instead of a single solid ring, the material is precision-machined into segments that interlock around a shaft, held together by springs (e.g., garter springs), creating a self-aligning, flexible, and sealed assembly .

These rings serve as the wear face in mechanical seals, matching against a counterface (metal, ceramic, or carbide). As the shaft rotates, the carbon\\\'s self-lubricating nature forms a microscopic graphite film on the mating surface, reducing friction and wear

\
1. \

   Reliable sealing with low friction—graphite film reduces wear and energy loss.

   \
\
2. \

   Self-aligning segments maintain contact and accommodate shaft tilt or shift.

   \
\
3. \

   Efficient thermal management—conducts heat away from seal surface.

   \
\
4. \

   Dry-running capability—ideal in steam or vapor sealing where lubrication is limited.

   \
\
5. \

   Maintenance-friendly—individual segments can be replaced within a cartridge assembly without full system disassembly.
