Tired of not getting all the air of out your brakes when changing calipers? Look no further, the solution is here. Pressure bleeding brakes with this perfect cap adapter. Tested on a 2008 Ford F-250. May work on other models/years

Items required: -spare reservoir gasket & punch a hole in the center to go along with this cap to allow for pressure bleeding of your brakes. -1/4" NPT fitting.

Support is needed for the 3 small lips that hold the cap to the reservoir. I printed in PLA and it worked great for the short job. Nylon 12 would be the best choice if going for a long term solution.
