Slade manufactures all of its own patented graphite yarns. The advantage is that each individual strand has it’s own unique core made out high tensile strength carbon fiber. The yarns are protected by US & EU patents. They were developed to conduct heat like steel alloys, to transfer the heat away from the shaft. When you compress by 25% (the denser the better), you have die-formed it into the stuffing box. So you don’t need flush-water to cool the shaft sleeve, in most applications. In addition, Slade reduces the number of oxidation sites in the packing yarns, so you can use 3300G in more severe temperature and severe chemical applications than other packings

Advantages of 3300G in pumps:

 One type for pumps and valves

• Works well on worn sleeves, Ra of 3,4 on 316 SS sleeves

• Difficult to over tighten

• No added lubricants to squeeze out or burn off

• Eliminates flush-water in most applications

• Not necessary to replace entire set, just add ring

• Doesn’t glaze or harden

• Eliminates most leaks

• Amperage reduction of 15% is typical

• No special end-rings required

• Outlasts typical packings by factor of 6

• 1800 fpm / 24 m/s (without flush-water)

• pH 1 – 14

• Operates virtually leak-free in most applications

Advantages of 3300G in valves:

• Lifetime Replacement Warranty.

• Each braided yarn reinforced with carbon fiber (600,000 PSI tensile strength)

• API Fire Tested (607 and 589 at 1,800°F/1,000°C)

• No special end-rings required.

• Carbon-corners on each ring of 3300G provide excellent Anti-Extrusion and Wiper Action. Good to 5,000 PSI.

• 3300G coats stem forming composite micro finish, resulting in low coefficient of friction.

• 30% compression of spooled 3300G "die-forms into the stuffing box". Eliminates need for dieformed rings

. • Reduces inventory and cost: a. By eliminating die-formed rings for each valve b. By having a few standard sizes for all valves c. Same packing for both pumps and valves d. If a leak develops, just add a ring

• Extremely high operating temperatures (typically: 1,800°F/1000°C). Excellent for “superheated steam.”

• "Live-loading" not required (no weight loss at temperatures up to 1,000 degrees F)

• Highly polished surfaces are not required (finishes between 8 to 30 RMS are fine)

• Handles media within full 1-14 pH.

• No lubricants, grease or impregnants that can be squeezed, washed or cooked out.

 • No wire reinforcement that could damage stem.
