Kaxite Sealing is a leading China braided packing manufacturer with over 25 years of expertise in valve and pump sealing solutions. Our braided gland packing is engineered from high-performance fibers including PTFE, graphite, aramid, carbon, and synthetic yarns – delivering reliable dynamic sealing across chemical processing, oil & gas, power generation, pulp & paper, and general industrial applications.
We supply custom braided packing in square and round cross-sections, available in a wide range of sizes (from 3mm to 50mm), with various lubricants and impregnations to match your specific media, temperature, and pressure requirements. With ISO 9001 certification, full material traceability, and fast delivery from our Ningbo facility, we are your trusted partner for OEM braided packing wholesale orders worldwide.
PTFE, graphite filament, aramid (Kevlar®), carbon fiber, and synthetic yarns – matched to your media, temperature, and pressure.
Square braid, interbraid, twisted, plaited, and die‑molded rings – each optimized for specific sealing requirements.
Full traceability, in‑house testing, and third‑party validation – ensuring consistent quality across every batch.
Supporting custom braided packing from small batches to bulk orders – typical lead time 15 days, FOB Ningbo.
Our braided packing is manufactured to international standards with precise fiber selection, braiding density, and lubricant impregnation. The table below provides a comprehensive comparison of our standard packing types – custom braided packing solutions are available for non‑standard applications.
| Packing Type | Primary Materials | Max Temp (°C / °F) | pH Range | Max Pressure (psi) | Key Features & Best For |
|---|---|---|---|---|---|
| Graphite Filament | Graphite-impregnated yarns (with Inconel wire option) | 650°C / 1200°F | 0-14 | ~2500 | Excellent thermal conductivity, self-lubricating. Handles steam, hot oils, acids, and alkalis. Ideal for high-speed pumps. |
| PTFE Braided | 100% PTFE filaments with lubricants | 290°C / 550°F | 0-14 | ~1500 | Superb chemical resistance, low friction, FDA compliant. Ideal for chemical, food, and pharmaceutical applications. |
| Aramid Fiber | Aramid fibers (Kevlar®) with PTFE or graphite lubricants | 290°C / 550°F | 2-12 | ~1800 | Extremely high tensile strength, abrasion resistant. Excellent for hot water, abrasive slurries, and high‑pressure valves. |
| Carbon Fiber | Carbon yarns with PTFE or graphite | 350°C / 660°F | 0-14 | ~2200 | High strength‑to‑weight, thermal stability, good chemical resistance. Used in pumps and agitators. |
| Acrylic Fiber | Acrylic fibers with lubricants | 150°C / 300°F | 2-12 | ~1200 | Good abrasion resistance, handles hot water, mild acids, and alkalis. Common in pulp & paper and general industrial service. |
| Flax / Jute | Natural fibers impregnated with waxes, oils, or graphite | 120°C / 250°F | 5-9 | ~800 | Economical, easy to install. Standard duty for cold water, treated water, and general‑purpose low‑speed applications. |
The braiding pattern directly influences the packing's density, flexibility, and sealing performance. We offer the following styles:
Proper lubrication is essential for reducing friction, dissipating heat, and extending packing life. We offer:
Our engineering team can develop custom braided packing with specialized lubricant formulations to match your operating conditions.

Contact Sales TeamBraided packing is used to create dynamic seals in pumps, valves, mixers, and other rotary or reciprocating equipment – preventing leakage of fluids, gases, and slurries.
Consider the media (chemical compatibility), temperature, pressure, shaft speed, and pH range. Our application engineers can assist with material selection – contact us with your operating conditions.
Yes, we manufacture custom braided packing in any cross‑section (square or round) from 3mm to 50mm, and any spool length – just provide your specifications.
Standard lead time is 15 working days after sample approval. Expedited options available – contact us for details.
Yes, every shipment includes material certificates and inspection reports – density, tensile strength, and lubricant content records available upon request.
The general rule is Number of Rings = Stuffing Box Depth ÷ Packing Cross‑Section. Typically 5‑6 rings for standard pumps, installed with staggered joints (90° offset).
