Asbestos Free(AF) Performance Packings - STYLE - 660

Pure Graphite Packing Ring

CHAMPION STYLE 660 is a high purity ( 99.00% to 99.9% carbon ), self lubricating and anti-frictional die molded, pre-formed gland packing ring manufactured from Flexible Pure Graphite Foil. These rings are manufactured in endless form or in 2 halves in oblique cut containing no oil or grease binder / additive of any kind.

CHAMPION STYLE 660 packing ring is totally free from any kind of contamination. For compression resistance and retention of size and shape the rings are manufactured with accurate specific density suitable to the working condition. These packing rings are having high thermal and dimensional stability and extremely low gas / fluid permeability, very low thermal expansion and extremely high chemical resistance. These rings are having low co-efficient of friction ( 0.08 to 0.1 against steel ) and hence, with continuous operation it polishes the stem / shaft and are also non abrasive in nature.

CHAMPION STYLE 660 Flexible Pure Graphite rings adjust to any irregularities under moderate pressure and have excellent resistance to pressure surge and thermal shock. These packing rings are chemically inert and also fire safe.

CHAMPION STYLE 660 packing ring is having inherent characteristics of basic graphite and hence having high degree of flexibility, compactibility, conformity and resiliency.
These rings expand radially to form perfect seal against the shaft and housing. Graphite is an extremely good thermal conductor and as such the packing dissipates heat away from the body leading to a longer life of the packing.

CHAMPION STYLE 660 is also manufactured for nuclear applications with slightly improved chemical properties. These packing's are stable even under exposure to high doses of nuclear radiation.
