FPM O-Ring 190x2.5 mm - High-Performance Fluoroelastomer Seal

Specifications, Applications & Benefits of the 190x2.5 FPM O-Ring

The FPM O-Ring 190x2.5 mm is a precision sealing ring made of FPM (fluoroelastomer / FKM / Viton®-type), with an inner diameter of 190 mm and cross-section (thickness) of 2.5 mm. This combination is engineered for demanding applications requiring superior chemical resistance, thermal stability, and longevity.

Key Features & Advantages

• Premium material - FPM: Excellent resistance to high temperatures, petroleum oils, fuels, hydraulic fluids, ozone, and aggressive chemicals.

• Optimal dimensions (190x2.5 mm): Suitable for large bore or thin-cross-section sealing grooves where space is tight but performance is critical.

• Low compression set: Maintains sealing force and shape over long-duration operation.

• High durability: Withstands cycles of pressure, temperature changes, and mechanical wear.

• Wide application range: Ideal for automotive fuel systems, chemical processing equipment, pumps, valves, and industrial machinery.

FAQ - Frequently Asked Questions

Q: What does “FPM” stand for and why use it?
A: FPM (fluoroelastomer) refers to a class of high-performance elastomers (often marketed as Viton® / FKM) renowned for heat, oil, fuel, and chemical resistance.

Q: What are the exact dimensions of this O-ring?
A: Inner diameter = 190 mm; cross-section (thickness) = 2.5 mm.

Q: In which temperature range can this O-ring operate?
A: Typical FPM materials can operate from around -20 °C to +200 °C (or greater for advanced formulations).

Q: Is it compatible with fuels, oils, and chemicals?
A: Yes - FPM is one of the preferred materials in systems with exposure to petroleum-based fluids, solvents, and aggressive media.

Q: Where is this O-ring commonly used?
A: In fuel systems, hydraulic and pneumatic equipment, chemical processing, pumps, valves, automotive applications, and any device requiring a robust seal under challenging conditions.

Q: Do you offer alternate variants or materials?
A: Yes — to avoid cannibalization, this listing is specific to FPM 190x2.5. Alternative variants (e.g. softer hardness, other diameters, EPDM or NBR materials) are offered separately.
