Flexible Graphite Braided Packing Rope, 3/8" x 3/8" x 12 Feet, High-Temp Pressure Resistant Seal for Pump Valve & Mechanical Repair, Leak Proof

High-Performance Flexible Graphite Packing: The Long-Lasting, Professional Seal Made from precision-braided, high-purity flexible graphite filament, this packing is engineered to solve pump and valve leakage and frequent downtime. It combines self-lubrication, high-temperature resistance, and chemical corrosion resistance to deliver durable and reliable sealing. Key Specifications Material: Flexible Expanded Graphite Size: 3/8 inch × 3/8 inch (Square Cross-Section) Length: 12 Feet per Roll (approx. 3.7 meters) Temperature Range: -200℃ to +500℃ Packaging: Individually Sealed Roll Core Advantages Long-Lasting Seal: Dense braided structure conforms tightly to shafts, effectively preventing leaks of water, oil, steam, and chemical media. Temperature & Pressure Resistant: Suitable for high-temperature and high-pressure conditions; withstands up to 1600℃ in non-oxidizing atmospheres. Self-Lubricating & Friction-Reducing: The natural lubricity of graphite reduces friction between the shaft and packing, lowering energy consumption and wear. Easy Installation: Flexible and easy to cut for quick on-site installation. The 12-foot length is sufficient for multiple repair jobs. Typical Applications Ideal for shaft and gland sealing in pumps, valves, agitators, and other rotating equipment across industries including petrochemical, power generation, water treatment, paper manufacturing, and marine. Installation Guidelines Cut rings at a 45° angle to match the shaft diameter, stagger joints by 90° or more, and tamp each ring evenly. After startup, adjust the gland gradually until a slight weep is achieved—avoid over-tightening.
