Flexible Graphite Gland Packing for Valves High-Temp Expanded Graphite Rope Seal Leak-Proof Industrial String(25 * 25 * 1000mm)
Extreme Environment Performance: Operates in temperatures from -328°F (-200°C) to 1200°F (650°C) and withstands pressures up to 4000 psi (275 bar) for versatile industrial applications.
High-Temperature Graphite Core: Pure graphite wire efficiently dissipates shaft friction heat, enabling high-speed rotation and minimized leakage in demanding conditions.
Multi-Equipment Compatibility: Self-lubricating, chemically inert, and thermally conductive design ideal for pumps, valves, grooves, and high-friction machinery.
Broad Chemical Resistance: Compatible with air, ammonia, oils, solvents, steam, corrosive fluids, and most industrial media except strong oxidizers.
Critical Media Sealing: Reliably seals high-pressure steam, hydrocarbons, cryogenic liquids, boiler water, and heat transfer systems under extreme thermal stress.
