Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
Premium PTFE - Based Spring Energized Seals
Superior - Performance Sealing Solutions for Harsh and Extreme Conditions
These premium PTFE-based spring energized seals stand out as high-performance industrial sealing solutions, blending durable PTFE material with resilient spring components. Engineered for reliability, they create a tight, leak-proof seal to prevent fluid leakage, critical for maintaining equipment integrity.
Ideal for harsh operating conditions—including high pressure, extreme temperatures, and corrosive environments—they outperform standard seals in stability and longevity. By minimizing downtime from leaks and reducing maintenance needs, they directly boost operational efficiency and cut costs. Whether for hydraulic systems, pneumatic equipment, or valves, these seals deliver consistent performance, making them a trusted choice for industrial sealing requirements.

1. Product Advantages
Forever Seals’ PTFE-based spring energized seals boast exceptional durability, thanks to high-quality PTFE material that resists corrosion, wear, and extreme temperatures (-200°C to 260°C). The integrated spring ensures consistent sealing force, eliminating leak risks even under high pressure (up to 50 MPa). Unlike standard seals, they require minimal maintenance, reducing downtime and operational costs for industrial users.
2. Working Principle
The seal combines a PTFE sealing element with a metal spring (stainless steel 316L optional). When installed, the spring exerts constant pressure on the PTFE lip, forcing it to adhere to the mating surface. As pressure increases, the fluid pressure further energizes the PTFE element, enhancing the seal tightness. This dual-energization design guarantees reliable sealing in dynamic and static applications.
3. Product Details
Material: Food-grade/industrial-grade PTFE; spring options include stainless steel 304, 316L, or Inconel.
Sizes: Customizable from 5mm to 500mm inner diameter; standard and non-standard dimensions available.
Certifications: ISO 9001, FDA, and RoHS compliant, meeting global industrial standards.
Surface Finish: Smooth PTFE surface (Ra ≤ 0.8μm) for low friction and reduced wear.
4. Application Range
Widely used in hydraulic cylinders, pneumatic valves, chemical reactors, pharmaceutical equipment, and automotive fuel systems. Suitable for industries like oil & gas, chemicals, food processing, and aerospace—where harsh conditions demand high-performance sealing.
5. FAQ
Q: Can it work with aggressive chemicals?
A: Yes, PTFE’s chemical inertness makes it compatible with acids, alkalis, and organic solvents.
Q: What’s the service life?
A: Up to 5,000 operating hours in typical conditions; longer in low-wear environments.
Q: Do you offer custom designs?
A: Absolutely—our engineering team tailors seals to specific pressure, temperature, and size requirements.
