PTFE Teflon® yarn coated with graphite and lubricated with an inert high temperature lubricant.

Hollow Core Gland Packing are specifically designed to reduce packing wear and shaft / sleeve wear in slow rotating equipments with excessive shaft run – out. Hollow Core Packing resists gland follower load and excessive run-out or whip in shaft.

Gland adjustments and repacking are greatly reduces. Months of in-plant testing have proved that reinforced yarn packing with square hollow core will outlast conventional packing in application associated with excessive shaft deflection on large shaft.
