Gasket GARLOCK® GRAPH-LOCK® Style 3124/3126 Flexible Graphite Sheet

Garlock GRAPH-LOCK Style 3124/3126 Flexible Graphite Sheet

Mechanical Advantages and 316 Stainless Steel Mesh Reinforcement Efficiency

• 316SS Wire Mesh Reinforcement: Contains a 0.0075-inch-thick 316 stainless steel wire mesh (24 mesh) insert to deliver extra mechanical resistance under high pressure.
• High Graphite Purity: Constructed from purified natural graphite flake layers with a minimum graphite content of 98% to withstand heat and aggressive chemicals.
• Proven Fire-Safe Certification: Verified fire-safe to provide elevated reliability standards across hazardous operational zones.
• Superior Torque Retention: Maintains stable seal tightness under moderate bolt loads while preserving dimensional stability during pressure fluctuations inside our comprehensive Katalog Gasket collection.
