Description
The BrakeQuip BQ1421 is a 9/16 in. inside-diameter copper crush washer, sized for banjo bolts and fittings that use this bolt diameter. Like all copper crush washers, it seals by deforming under torque to fill surface imperfections — a one-time seal that should be replaced with a new washer any time the banjo bolt is removed, rather than reused. BrakeQuip Products stocks the full range of copper washer inside diameters used across common banjo bolt sizes.
