EO-3 | Parker Flareless Tube Fittings | Metric

Parker EO-3 Fitting System

EO-3 is an innovative Parker flareless fitting for metric tubing similar to the EO and EO-2 series. The EO3 flareless fitting system utilizes a visual indicator to prevent leakage due to inadequate or over-tightening, allowing the user more control to make high-quality, fast connections.

EO-3 metric tube fittings are constructed with a new mechanical tapered thread and tube design to eliminate blow-out equipment failures. The steel fittings feature a compact design, octagonal nut, integrated soft-sealing cone ring and elastomer seal for leak free connections. EO3 can also be connected to EO2 fittings using an adapter.

EO3 Tube Fittings Features:

  • Pressure Rating: Up to 6,000 psi for all tube sizes
  • Fitting Material: Steel with chromium 6 free plating
  • Tube Material: Conventional hydraulic steel, e.g. E235 (ST37) or E355 (ST52.4) standard to DIN EN 10305
  • Elastomer material: NBR
  • Temperature Resistance: -40° to 248°F (-40°C to 120°C)
