Hongwo Braided Packing
Defying Pressure Limits with Reinforced Architecture
Hongwo’s PTFE with Aramid in Corners Reinforced Braided Sealing Packing introduces a revolutionary hybrid construction that merges PTFE’s chemical resistance with aramid’s unparalleled tensile strength. Specifically engineered for high-pressure, high-cycle applications, our patented corner reinforcement technology prevents packing extrusion while maintaining the flexibility required for dynamic sealing – delivering up to 3X longer service life compared to standard braided designs.
Where Extreme Pressure Meets Precision Motion
⚙ Hydraulic Press Cylinders – Withstands 3,500+ psi pulsating pressure
⚙ Offshore BOP Rams – API 16A compliant for blowout preventers
⚙ High-Speed Mixer Shafts – Handles 1,200 RPM with zero fiber breakout
⚙ Mining Slurry Pumps – Resists abrasive media with corner armor protection
⚙ Steel Mill Descaling Systems – Endures 200°C water jets at 250 bar

Breakthrough Reinforcement Technology
✧ Triaxial Corner Lock System
- 45° Aramid Weave – Precisely oriented fibers in high-stress zones
- PTFE Encapsulation – Seals reinforcement against media penetration
- Interlocking Braid – Mechanical keying prevents layer separation
✧ Dynamic Response Features
• Pressure-Activated Compression – Aramid fibers engage progressively with load
• Torsional Compliance – Maintains seal integrity during shaft deflection
• Memory Recovery – Returns to original shape after pressure spikes
Why Engineers Specify This Packing
✓ Extrusion-Proof Design – Zero gland leakage even with 0.1mm clearance
✓ Dual-Material Synergy – PTFE handles chemicals, aramid absorbs stress
✓ Vibration Damping – Reduces shaft whip by 60% vs. rigid packings
✓ Installation-Friendly – Pre-lubricated for immediate dry-start protection
Specialized Configurations Available:
- MarinePro™ – Saltwater-optimized with corrosion inhibitors
- FoodShield™ – FDA-compliant for edible oil processing
- UltraTorque™ – Low-friction coating for high-RPM applications
Field Validation Data:
▶ 14-month continuous service in 3500psi hydraulic forging press
▶ 92% reduction in gland adjustment frequency vs. conventional packing
▶ Zero extrusion failures in API 16A qualification testing
