Gland Packing JIC 3077 is a type of compression packing made from a combination of graphite-PTFE (Polytetrafluoroethylene) fibers braided together with aramid fibers. This combination produces a strong, heat-resistant, and chemically resistant seal with self-lubricating properties.
Key Characteristics
Composition: Braided combination of graphite-PTFE and aramid fibers.
Temperature Resistance: Capable of operating at temperatures up to 260°C (500°F).
Chemical Resistance: Resistant to corrosive fluids, organic solvents, steam, hot water, and oils. Ideal pH range: 2–14.
Lubrication: Self-lubricating properties help reduce friction and wear on shafts.
Mechanical Strength: The aramid fibers provide excellent mechanical strength, making the packing durable and highly resistant to abrasion.
Typical Applications
Gland packing JIC 3077 is designed for use in various industrial equipment, including:
Pumps: Rotary and chemical pumps.
Valves: Valves operating under high temperature and pressure.
Machinery: Rotary machines and agitators.
Fluids: Corrosive liquids, organic solvents, hot water, oils, and steam.
Comparison with Other Packing Types
Compared to other types of gland packing, JIC 3077 offers a unique balance of mechanical strength from aramid fibers and chemical resistance plus lubrication from graphite-PTFE. This makes it a versatile choice for demanding operating conditions.
