Not all carbon fiber packings are created equal. The two attributes that differentiate carbon fiber packing are purity levels and whether the yarn is made from a continuous filament or from staple fibers. Higher carbon purity improves the temperature and chemical resistance of the braid while the fiber type affects sealing. Simply put, braid constructed from staple fibers conforms to the stuffing box better, requiring lower gland load to make a seal. That lower gland load translates into a packing that will last up to 3 times longer than those made from continuous filaments. It also means that there will be less frictional drag on the shaft which translates to energy savings in rotating equipment and easier operation in valves. Garlock compression packing is designed to give the user the greatest return on initial investment in terms of leakage control, service life, and dependable, cost-effective product.
