SAE J518 Split-Flange Covers

In stock

SAE J518 Split-Flange Covers help protect machined surfaces on split flanged connections. They feature an internal-locking bead design that provides a secure fit, that requires no fasteners.

Manufactured in a natural translucent Polyethylene, so that the O-Ring assembled on the flange remains visible through the cap.

The range includes two series options. The Q Series are used on SAE Code 61 3000 PSI high pressure flanges. The HP Series are used on SAE Code 62 6000 PSI high pressure flanges.

Ensure you select an appropriate protector by first measuring both the Outside Diameter and Bolt Circle Diameter of your flange.

  • Material: Polyethylene (PE)
  • Colour: Natural (Translucent)
