Pump Shaft Seal，- 4x4MM - 32FT Long

Key features

• Flexible Cutting & On-site AdaptationConstructed from highly flexible graphite material. It fits closely to eliminate leakage entirely, generates low startup torque and causes no abrasion or damage to matched mechanical equipment.
• Reinforced High-Strength MaterialThis heavy-duty packing is woven with high-purity expanded graphite yarn, and metal wire or fiber reinforcement is available as an option. Its upgraded dense braided structure offers superior mechanical strength and great impact resistance, staying free from deformation and loosening after long-term heavy-load operation.
• Ultra-High Pressure & Temperature ResistanceIt delivers stable sealing performance at standard working temperatures from -200℃ to 800℃, and maintains reliable performance up to 1600℃ under non-oxidizing conditions, with a maximum pressure resistance of 45MPa. It can fully adapt to harsh heavy-duty industrial environments with ultra-high pressure and extreme heat.
• Complete Size Range & Flexible Length OptionsA full lineup of square cross-section sizes from 4×4mm to 20×20mm is provided, and roll lengths are available between 1m and 31m. It is a reliable sealing choice for large pumps, valves and reactors deployed in power plants, chemical plants, steel mills and mines, especially suitable for harsh working conditions with solid particles and severe abrasion.
• Customized Industrial Sealing SolutionsWe support custom specifications, customized roll lengths and bulk order customization, so as to develop exclusive sealing solutions to satisfy diverse industrial sealing and installation demands.

PIPRE Universal Flexible Graphite Braided Packing is a solid pure graphite sealing cord woven from premium fully graphitized yarn. It boasts a tight integrated braided structure with no extra binder added. As a standard industrial sealing medium, it comes with great pliability, superior self-lubricating capacity and ultra-low friction coefficient. Even after long continuous running, it will not scratch or abrade equipment shafts. Its steady, uniform sealing effect makes it an ideal pick for most regular static and dynamic industrial sealing scenarios. Key Technical Parameters: Working Temperature: -200℃ ~ 800℃ Max Working Pressure: 40MPa Max Linear Velocity: 20m/s Applicable pH Value: 2–14 Cross Section Form: Square Available Sizes: 4×4mm, 10×10mm, 12×12mm, 18×18mm, 20×20mm Custom Service: Customizable lengths are available to fit various on-site sealing and assembly demands. This graphite packing features light weight and great wear resistance, and fits all kinds of uneven sealing surfaces perfectly. It can be freely cut for quick trimming and easy installation on site. It retains stable physical characteristics under ultra-high/low temperature and high-pressure working environmen
