Brake Fluid Reservoir Moisture Barrier
Diaphragm moisture and spill barrier to fit remote reservoirs. Fits under the cap to allow fluid level to vary and precludes atmospheric contact which helps to keep water out of the fluid. This is the larger size to fit the Girling or OBP remote reservoirs that we sell. Measures approx. 63mm diameter (at the flange) and 50mm long when extended (as pictured).
