Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
PEEK - based Spring Energized Seals for Chromatograph
Reliable and High - performance Sealing Solution for Chromatographic Equipment
Engineered for chromatographic instruments, our PEEK-based Spring Energized Seals combine high-performance PEEK material with a spring-energized design. They offer excellent resistance to organic solvents, acids, and alkalis—avoiding swelling or degradation that harms accuracy—and maintain reliable sealing from -20°C to 220°C, adapting to chromatograph temperature fluctuations.
With strong mechanical strength and wear resistance, these seals ensure long durability, reducing replacement needs and downtime. Ideal for HPLC and precision systems, they deliver leak-free performance to support stable instrument operation and trustworthy analytical results.

1. Product Advantages
Superior Chemical Resistance: Made of high-grade PEEK (Polyether Ether Ketone), the seals resist most organic solvents, acids, and alkalis used in chromatography—preventing swelling, degradation, or leakage that could distort analytical results.
Wide Temperature Adaptability: Maintain stable sealing performance from -20°C to 220°C, easily handling temperature fluctuations in chromatograph operations (e.g., HPLC column heating/cooling cycles).
Long-Lasting Durability: PEEK’s inherent mechanical strength and wear resistance reduce friction and tear during repeated use, extending service life and lowering replacement frequency.
Consistent Sealing Pressure: The spring-energized design ensures constant contact with sealing surfaces, even under low pressure or slight surface irregularities, eliminating leak risks.
2. Working Principle
Forever Seals’ PEEK Spring Energized Seals rely on a dual-action mechanism:
The embedded spring provides initial preload, forcing the PEEK sealing lip to adhere to the mating surface and form an initial seal.
As chromatograph system pressure increases, the pressure further compresses the spring and deforms the PEEK material, enhancing contact with the sealing surface—ensuring tight, leak-free performance throughout operation.
3. Product Details
Material Grade: Medical/industrial-grade PEEK (compliant with industry standards for low extractables, avoiding sample contamination).
Spring Options: Stainless steel 316L springs (corrosion-resistant, compatible with PEEK and harsh chromatographic environments).
Size Range: Customizable from 3mm to 50mm inner diameter, fitting most standard chromatograph fluid paths (e.g., HPLC pumps, injection valves).
Surface Finish: Polished PEEK surface (Ra ≤ 0.8μm) to minimize friction and prevent fluid turbulence.
4. Application Range
Specifically designed for chromatographic equipment, including:
High-Performance Liquid Chromatography (HPLC) systems (pumps, columns, detectors).
Ultra-High Performance Liquid Chromatography (UHPLC) systems (supporting high-pressure operations up to 15,000 psi).
Gas Chromatography (GC) accessories (sample injectors, carrier gas lines).
Laboratory analytical instruments requiring chemical-resistant, precision sealing.
5. FAQ
Q1: Can these seals be used with aggressive solvents like methanol or acetonitrile?
A1: Yes—PEEK’s chemical inertness ensures compatibility with most common chromatographic solvents, including methanol, acetonitrile, and strong acids (e.g., 10% HCl).
Q2: What is the typical service life of these seals?
A2: Under normal chromatograph operating conditions (8 hours/day, 5 days/week), the seals last 12–18 months—2–3 times longer than standard rubber or PTFE seals.
Q3: Does Forever Seals offer custom sizes for non-standard chromatograph parts?
A3: Absolutely—we provide custom design and manufacturing within 7–10 business days, based on your equipment’s dimensional specifications.
6. Company Selling Points (Forever Seals)
