Product Overview
Our Cotton Packing with Graphite & Oil is a cost-effective sealing solution designed for general industrial and marine applications. Manufactured from high-quality cotton yarns, thoroughly impregnated with graphite and mineral oil, this packing offers excellent flexibility, easy installation, and reliable sealing performance in low to medium pressure and speed conditions. The graphite and oil impregnation provides self-lubricating properties, reduces friction, and helps dissipate heat, extending the service life of both the packing and the shaft.
This Cotton Packing with Graphite & Oil is particularly suitable for older equipment, water pumps, and applications where an economical replacement for asbestos or synthetic fiber packing is desired. Its soft, pliable nature allows it to conform easily to worn or slightly misaligned shafts, making it a practical choice for maintenance and repair operations.
Key Advantages:
-
Low cost with dependable performance for general sealing
-
Graphite and oil impregnation ensures self-lubrication and reduced shaft wear
-
Soft and pliable construction simplifies installation and minimizes gland adjustment
-
Good resistance to water, oils, and mild chemicals
-
Available in a wide range of sizes for shafts and valve stems
-
Environmentally safer than asbestos-based packing

Why Choose Our Cotton Packing with Graphite & Oil?
1. Economical Sealing Solution
For applications where high-performance synthetic packing is unnecessary, our Cotton Packing with Graphite & Oil provides a budget-friendly alternative without sacrificing basic sealing reliability. This makes it ideal for maintenance budgets and high-volume OEM use.
2. Self-Lubricating Properties
The graphite and oil impregnation ensures that the packing remains lubricated throughout its service life. This reduces friction between the packing and the shaft, lowers operating torque, and prevents overheating in low-speed applications.
3. Easy Installation and Adjustability
Cotton fibers are inherently soft and compressible. Our Cotton Packing with Graphite & Oil can be easily cut, formed, and installed even in tight stuffing boxes. It also conforms well to worn shafts and oversized glands, reducing leakage without excessive gland pressure.
4. Versatile Size Range
We supply Cotton Packing with Graphite & Oil in cross-sections from 3 mm to 50 mm, as well as in continuous coils or pre-cut rings. Custom sizes and packaging are available for OEM customers.
5. Environmentally Friendly
Unlike traditional asbestos packing, our Cotton Packing with Graphite & Oil contains no hazardous fibers. It is safe to handle, easy to dispose of, and meets modern environmental and workplace safety standards.
6. Consistent Quality Control
Every batch of our Cotton Packing with Graphite & Oil is tested for density, lubricant content, and dimensional accuracy. As an ISO 9001-certified manufacturer, we ensure consistent product performance shipment after shipment.

Frequently Asked Questions
Q: What is the maximum temperature this Cotton Packing with Graphite & Oil can withstand?
A: Our Cotton Packing with Graphite & Oil is rated for continuous service up to +120°C. For higher temperatures, we recommend our aramid or PTFE packing series. The graphite and oil lubricant remains stable within this temperature range.
Q: Is this cotton packing suitable for drinking water or food applications?
A: Standard Cotton Packing with Graphite & Oil contains mineral oil and graphite and is not recommended for potable water or food-contact use. For such applications, we can supply special food-grade cotton packing with FDA-approved lubricants. Please specify your requirements.
Q: Can I use this packing on high-speed shafts?
A: The maximum recommended shaft speed is 6 m/s. For speeds above this, the cotton fibers may overheat and degrade. We suggest using our aramid or PTFE packing for high-speed applications.
Q: What is the shelf life of the Cotton Packing with Graphite & Oil?
A: When stored in a cool, dry place in its original packaging, the packing has a shelf life of 24 months. The graphite and oil impregnation remains stable, and the cotton fibers retain their flexibility during this period.
Q: Do you offer pre-formed rings instead of coils?
A: Yes, we can supply Cotton Packing with Graphite & Oil in pre-cut or die-formed rings to match your stuffing box dimensions. Please provide the shaft diameter and gland bore so we can produce accurate rings.
