Slade Packing
Slade 3300G carbon fiber reinforced graphite foil packing: flush free for many applications, rated -400°F to 1800°F, pH 0 to 14, 4800 fpm, and 5000 psig, with a low chloride version for nuclear service.
Slade builds packing from graphite foil yarn reinforced with carbon fiber, which gives the ring the heat transfer and chemical resistance of pure graphite with the strength to run at high shaft speeds without a flush. The result is a single style that covers chemicals, steam, hydrocarbons, and abrasive slurries in one stuffing box.
Anchor Seals Inc. stocks Slade Style 3300G by the spool and as pre-cut rings, and can supply the low chloride version for nuclear applications. Send us the media, temperature, and shaft size and we will confirm the fit.

Frequently Asked Questions
All Mechanical PackingsWhat does flush free mean?
Most graphite packings on hot or abrasive service need a clean flush water supply to cool and lubricate the stuffing box. Style 3300G conducts heat away from the shaft well enough that many applications can run without a flush, which cuts water use and removes the flush piping from the installation.
Can Style 3300G handle abrasive slurries?
Yes. The carbon fiber reinforcement holds the graphite foil yarn together under abrasive attack, so 3300G seals slurries that would tear apart an unreinforced graphite packing.
Is there a nuclear grade?
Yes. A low chloride version of Style 3300G is available for nuclear applications where chloride content must be controlled. Ask for it when you request a quote.
How does 3300G compare to other graphite packings?
It combines the temperature and chemical range of pure graphite (-400°F to 1800°F, pH 0 to 14) with a shaft speed rating of 4800 fpm and pressure rating of 5000 psig, which puts it among the most versatile single styles Anchor Seals Inc. stocks.
