Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
High-Quality Spring Energized Seals for Industrial Use
Corrosion-Resistant and High-Temperature Resistant Sealing Solutions
Our spring energized seals are high-performance solutions engineered for tough industrial environments. They combine exceptional corrosion resistance and reliable high-temperature stability, ensuring consistent operation even with aggressive chemicals, extreme heat, or fluctuating pressure.
Crafted via advanced manufacturing, these seals have a smooth, wear-resistant surface and elastic compensation mechanism. This design guarantees tight, leak-proof contact to prevent fluid/gas leakage—critical for chemical processing, oil & gas, new energy, and heavy machinery sectors.
Their versatile design fits diverse equipment specs, reducing compatibility issues. By minimizing downtime from seal failures and lowering maintenance needs, these seals deliver long-term value for efficient, cost-effective operations.

1. Product Advantages
- Dual Resistance for Harsh Conditions: Exceptional corrosion resistance (against aggressive chemicals, oils, and solvents) and high-temperature stability (operates reliably from -50°C to 250°C, depending on material), outperforming standard O-rings in extreme environments.
- Zero Leakage Guarantee: Equipped with a precision metal spring (stainless steel 304/316) that provides constant contact force—ensures tight sealing even when equipment experiences pressure fluctuations or minor dimensional wear.
- Long Service Life: Made of premium PTFE, PEEK, or FKM composites; these materials resist abrasion, aging, and deformation, reducing replacement frequency by 60% compared to conventional seals.
- Low Maintenance: Lightweight design and compatibility with standard sealing grooves minimize installation time; no frequent adjustments needed during operation.
2. Working Principle
Forever Seals’ spring energized seals operate on a “spring-driven compensation” mechanism:
- The metal spring (core component) exerts continuous radial/axial force on the seal’s polymer jacket.
- When installed in equipment, the spring pushes the jacket tightly against the mating surface, creating an initial seal.
- As pressure increases or temperature changes, the spring expands/contracts to adjust the jacket’s contact force—compensating for wear, thermal expansion, or minor surface irregularities, and maintaining leak-proof performance.
3. Product Details
- Materials:
- Jacket: Food-grade PTFE (for low friction), chemical-resistant PEEK (for high pressure), or oil-resistant FKM (for dynamic applications).
- Spring: Stainless steel 304 (general use) or 316 (corrosive environments like marine/chemical plants).
- Dimensions: Customizable from 5mm to 500mm inner diameter; standard and metric sizes available (ANSI, DIN, ISO compliant).
- Certifications: RoHS, REACH, and FDA certified (suitable for food, pharmaceutical, and medical equipment).
- Design Features: Smooth jacket surface (reduces friction in dynamic applications), chamfered edges (prevents damage during installation), and laser-marked part numbers (easy identification).
4. Application Range
Forever Seals’ spring energized seals serve diverse industries where reliability in harsh conditions is critical:
- Oil & Gas: Downhole tools, wellhead equipment, and pipeline valves (resists crude oil, drilling fluids, and high pressure).
- Chemical Processing: Reactors, pumps, and mixers (handles acids, alkalis, and solvents).
- New Energy: EV battery cooling systems, hydrogen fuel cell gaskets, and solar panel manufacturing equipment (withstands temperature cycles and coolant corrosion).
- Food & Pharmaceutical: Sanitary pumps and processing machinery (FDA-compliant materials, no contamination risk).
- Heavy Machinery: Hydraulic cylinders, excavator valves, and turbine seals (tolerates vibration and heavy loads).
5. FAQ
Q1: Can the seals be customized for non-standard equipment sizes?
A: Yes. Forever Seals offers 7-day rapid prototyping for custom dimensions—simply provide your equipment’s groove size and operating conditions.
A: Yes. Forever Seals offers 7-day rapid prototyping for custom dimensions—simply provide your equipment’s groove size and operating conditions.
Q2: What’s the difference between your seals and standard PTFE seals?
A: Standard PTFE seals rely on static pressure and may fail under low pressure or wear. Our seals add a metal spring for dynamic force compensation—ensuring sealing even in low-pressure or high-wear scenarios.
