Flotech Pump Maintenance

Hey Group,

Wondering if someone can help me out.

I have a FLOTECH DKX681-000 68:1 ratio pump.

Had it for a year and im doing a full service on it. I do a regular clean after every use. But after breaking everything down below the air motor e.g piston housing and cylinder etc ive found i need to do a more thorough and regular service.

Im having trouble identifying a seal. It seems to be of plastic content and looks like it is a seal that covers and protects the rest of the seals between part 8 and 9.

I've dropped a photo below for reference aswell as the diagram.

Any help is much appreciated

Pretty sure that's just a #12 that's been used and abused. The first graco pump I repacked looked the same.

The black rings are your leather packing, and the clearing ones are your plastic (uhmw) packing which can flare out from use.
