Round Cartridge Cores

Cartridge cores are constructed when flaring dies are driven into copper or brass tubes.  Core faces are dipped to seal the water from the air.  They are occasionally confused with film cores and frequently referred to as "honeycomb cores" but the patterns are varied and curves, angles and steps can be created.  Please contact us with the year, make, model and dimensions of the core.  Sketches and core pencil rubbings can be used to best match the correct core to your vehicle.  We'll cost out the core.

We make to order. Please allow adequate time for us to build.
