Selecting the right Pure Graphite PTFE Packing with Oil requires careful consideration of several key factors. At Ningbo Kaxite Sealing Materials Co., Ltd., our factory has extensive experience helping customers identify the most critical elements that influence sealing performance and longevity. Understanding these key factors will allow our clients to choose the optimal packing for their applications, whether it involves high temperatures, aggressive chemicals, or dynamic operations.
Material composition is one of the most important key factors when selecting Pure Graphite PTFE Packing with Oil. Our factory ensures that our packing combines high-purity PTFE with finely processed graphite and compatible lubricating oil. This combination delivers excellent chemical resistance, thermal stability, and low friction performance, which are essential for both static and dynamic applications.
Our Pure Graphite PTFE Packing with Oil is formulated to meet these key factors, providing both durability and adaptability in challenging industrial conditions.
| Parameter | Specification | Benefit | Selection Guidance |
| PTFE Purity | 99% | Excellent chemical resistance and low friction | Choose higher purity for strong acids and solvents |
| Graphite Content | 5-10% | Enhanced thermal conductivity and strength | Higher content for high-temperature applications |
| Oil Infusion | Graphite-compatible lubricating oil | Reduced shaft wear and leakage | Use oil-infused packing for dynamic shafts |
| Temperature Range | -200 to 280°C | High-temperature endurance | Select based on maximum operational temperature |
| Pressure Tolerance | Up to 25 MPa | Reliable sealing under high-pressure conditions | Choose packing rated above system pressure |
Temperature and pressure are two critical key factors when selecting Pure Graphite PTFE Packing with Oil. Both parameters directly influence the material's performance, sealing reliability, and lifespan. Our factory emphasizes understanding these conditions to ensure optimal selection for any industrial application.
Thermal stability is a key factor in ensuring long-term performance. Our Pure Graphite PTFE Packing with Oil is designed to withstand extreme temperatures, from -200°C in cryogenic applications to 280°C in high-temperature processes. Key points include:
Pressure tolerance is another key factor for selection. Packing must resist system pressure while maintaining sealing integrity. Key points include:
Temperature and pressure interact and jointly affect packing performance:
Operational context is a key factor when evaluating temperature and pressure requirements:
To simplify selection, consider the following table summarizing temperature, pressure, and key material considerations:
| Factor | Recommended Specification | Key Benefit | Selection Guidance |
| Maximum Temperature | -200°C to 280°C | Thermal stability | Choose higher graphite content for high-temperature use |
| Operating Pressure | Up to 25 MPa | Maintains seal under pressure | Select packing rated above system pressure by 20% |
| Dynamic Applications | Oil-infused PTFE with graphite | Reduced friction and wear | Use for pumps, rotating shafts, valves in motion |
| Static Applications | High compressive strength PTFE/graphite | Long-term sealing integrity | Use for stationary valves, tanks, and flanges |
| Temperature & Pressure Interaction | Engineered combined stress resistance | Reliable sealing across conditions | Consider both maximum temperature and pressure together |
By carefully analyzing temperature and pressure, our customers can select Pure Graphite PTFE Packing with Oil that meets all operational requirements. These key factors play a decisive role in long-term performance, minimizing maintenance, and ensuring reliable sealing across a wide range of industrial applications.
Chemical compatibility is a critical key factor when selecting Pure Graphite PTFE Packing with Oil. In industrial applications, packing is often exposed to aggressive chemicals such as acids, alkalis, solvents, and oxidizing agents. Choosing a packing material that can withstand these environments ensures long-term sealing performance, reduces maintenance, and prevents unexpected failures. Our factory carefully formulates packing to address these chemical challenges while maintaining mechanical strength and flexibility.
Understanding the chemical environment is essential for proper selection. The following factors are key considerations:
To simplify the selection process, consider these key steps:
| Chemical Type | Resistance of Pure Graphite PTFE Packing with Oil | Selection Guidance |
| Strong Acids (HCl, H2SO4) | Excellent | Use high-purity PTFE packing for high-concentration acids |
| Alkaline Solutions (NaOH, KOH) | Excellent | Ensure proper graphite content for temperature stability |
| Solvents (Acetone, Alcohols) | Very Good | Choose oil-infused packing for dynamic shafts |
| Oils and Lubricants | Excellent | Use oil-infused packing to reduce friction and wear |
| Oxidizing Agents (H2O2, Chlorine) | Good | Higher graphite content recommended for long-term exposure |
By evaluating chemical compatibility carefully, our customers can select Pure Graphite PTFE Packing with Oil that meets operational demands. Considering these key factors ensures reliable sealing, minimizes maintenance costs, and enhances long-term performance in any chemical processing application.
Dimension and design selection are key factors influencing sealing efficiency. Our factory offers a wide range of Pure Graphite PTFE Packing with Oil to meet diverse requirements.

Q1: What is the most important key factor in selecting Pure Graphite PTFE Packing with Oil for high-temperature applications?
The material composition and graphite content are critical key factors. Higher graphite content enhances thermal stability and ensures long-lasting performance at elevated temperatures.
Q2: How does the graphite content influence the key factor of thermal resistance?
Graphite improves heat dissipation and maintains packing flexibility, making it a key factor for maintaining seal integrity in high-temperature environments.
Q3: Which key factors should be prioritized when sealing aggressive chemicals?
PTFE purity and chemical compatibility are key factors. High-purity PTFE resists strong acids, alkalis, and solvents, preventing degradation and ensuring reliability.
Q4: How do pressure ratings serve as a key factor in packing selection?
Operating pressure determines the required compressive strength of the packing. Selecting a pressure rating above system conditions is a key factor for preventing leakage.
Q5: Why is dimension accuracy considered a key factor in ensuring optimal performance?
Accurate dimensions ensure proper fit and compression. Overly thick or thin packing can cause leaks or damage, making dimension selection a key factor in reliability.
