Description
Product Description
IKSONIC CO., LTD. presents the high-performance Axial RVA Spring Energized Seal (also known as a spring-energized PTFE seal or carbon fiber filled PTFE seal). Designed for demanding shaft sealing applications, this seal combines a corrosion-resistant PTFE jacket with a carbon fiber reinforcement for exceptional durability and low friction. The internal spring provides constant radial load, ensuring reliable sealing even under extreme temperatures, high pressures, and aggressive media. As a China factory, we offer direct supply and custom manufacturing per your drawings.
Key Features
- High Temperature Resistance: Operates reliably in environments from -200°C to +300°C.
- Corrosion & Chemical Resistance: PTFE and carbon fiber construction withstands aggressive chemicals and harsh media.
- Low Friction & Long Life: Self-lubricating PTFE reduces wear and extends service life.
- Spring Energized Design: Ensures consistent sealing force, compensating for wear and thermal expansion.
- Custom Manufacturing: We are a China factory; we can produce seals per your exact drawings and specifications.
Q&A
1. What is the main application of this seal?
This seal is primarily used for reciprocating and rotary shaft applications in pumps, valves, compressors, and hydraulic cylinders where high temperature and corrosion resistance are required.
2. What materials are used in this seal?
The seal jacket is made of PTFE (polytetrafluoroethylene) reinforced with carbon fiber. The energizing spring is typically made of stainless steel or Hastelloy.
3. Can you provide custom sizes?
Yes, as a factory, we specialize in custom manufacturing. Please send us your drawings or specifications, and we will produce the seal to your exact requirements.
4. What is the temperature range for this seal?
The standard operating temperature range is -200°C to +300°C, depending on the specific PTFE compound and spring material.
5. Is this seal suitable for high-pressure applications?
Yes, the spring-energized design allows it to seal effectively at pressures up to 300 bar (4350 psi) or higher with proper groove design.
6. How does the spring energizer work?
The internal spring applies a constant radial load against the shaft, ensuring the seal lip maintains contact even as the PTFE wears, providing a leak-free seal over a long service life.
7. What is the lead time for custom orders?
Lead time depends on complexity and quantity. Typically, custom seals can be produced within 2-4 weeks after drawing approval.
8. Do you offer samples for testing?
Yes, we can provide samples for evaluation. Please contact our sales team with your requirements.
