O-rings and seals are precision-engineered sealing components used in fuel injectors to prevent fluid leakage and maintain pressure integrity.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| OD | 2-50 mm | |
| Hardness | 70-90 Shore A | |
| Cross Section | 1-5 mm | |
| Compression Set | <25% | |
| Pressure Rating | Up to 2000 bar | |
| Temperature Range | -40°C to 200°C |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
A precision component that atomizes and delivers fuel into the combustion chamber at high pressure.
A hydraulic connector that enables rapid attachment and detachment of hydraulic tools to mini excavators without fluid leakage.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Common causes include chemical degradation from fuel additives, thermal aging at high temperatures, compression set from permanent deformation, extrusion under high pressure, and improper installation damage.
Typically during injector servicing or every 100,000-150,000 miles, but always inspect during maintenance and replace if signs of hardening, cracking, or swelling are present.
No, O-rings should never be reused due to compression set and potential micro-damage. Always install new, lubricated seals during assembly.
