Sight Glass Repair Kit For 5204SFI API Bottom Load Valve

The 5204K13 is specifically identified by Dixon as the sight glass repair kit for the 5204SFI API valve. It is intended for the SFI full-body sight glass configuration rather than the standard smaller sight glass used on other 5204 valve arrangements.

Confirm the valve model before ordering because Dixon offers several different repair kits within the 5204 family. The 5204K13 should be selected when servicing the full-body sight flow indicator used on the 5204SFI.

The kit includes the replacement SFI sight glass used to provide visual indication through the valve body during loading and unloading operations. Replacing the sight glass restores visibility when the existing component is damaged, cracked, or otherwise no longer serviceable.

Inspect the replacement component before installation and keep sealing surfaces clean during assembly. Damage to the sight glass or contamination at the sealing interface can affect the completed repair.

Dixon includes a Baylast™ O-ring or sealing component with the 5204K13 kit. The seal fits within the sight glass assembly and helps maintain the required interface between the replacement sight glass and valve body.

The old seal should not be reused during repair when the replacement kit provides a new sealing component. Inspect the seal groove and surrounding surfaces before assembly so the new Baylast™ component can seat correctly.

The kit also includes the retaining component used to secure the SFI sight glass assembly in position. Dixon's repair documentation identifies the 5204K13 as a complete sight glass service kit rather than an individual replacement window.

Follow Dixon's maintenance instructions when disassembling and reinstalling the sight glass assembly. Confirm the retainer is fully seated and inspect the repaired valve before returning it to loading or unloading service.
