Tapered O-Ring Hydraulic Fitting
A tapered o-ring hydraulic fitting utilizes a tapered O-ring that is compressed into a conical seat. As the fitting is tightened, the tapered O-ring conforms to the conical seat, creating a tight seal. This design is particularly effective in applications where there may be variations in component tolerances or where a self-tightening seal is required.
