NEBCO Anti-Keystone®
Reduce leakage, equipment wear and packing failure
Conventional packing can deform around a shaft, creating uneven pressure, friction, leakage and premature equipment wear. NEBCO ANTI-KEYSTONE® II compression packing maintains more uniform contact and density for a more reliable, efficient seal.
THE ANTI-KEYSTONE DIFFERENCE
A better seal starts with a better packing design
ANTI-KEYSTONE® packing is braided in a unique trapezoidal, six-sided shape that becomes square in the gland. This design increases surface contact and maintains more uniform pressure around the shaft for a tighter, more reliable seal.
FEATURED COMPRESSION PACKING
Four styles for demanding applications
Style 106 AK II®
Abrasive and slurry service
- Resists abrasion and extrusion
- Handles slurries and solids
- Extended service life
Style 274 AK II® Hydropacking®
Flexible general-service sealing
- Broad chemical compatibility
- Low friction and heat generation
- Ideal for pumps and valves
Style 702 AK II®
High-speed heat dissipation
- Designed for higher speeds
- Excellent heat transfer
- Reduces shaft wear
Style 7800 AK II®
Versatile graphite packing
- High purity graphite yarns
- Excellent chemical resistance

SC RESILIENT-CORE OPTIONS
Added resilience for unstable equipment
SC options feature strategically placed silicone cores that add resilience and help the packing respond to shafts that are out of round, vibrating or exposed to impact. Combined with ANTI-KEYSTONE® II technology, this can help minimize leakage, reduce gland adjustments and extend packing life.
PRE-SIZED RING SETS
Packing prepared for faster installation
Pre-sized ring sets are cut to the correct length and quantity for your equipment, helping you save time, reduce waste and ensure a proper fit.
