An integrated part of the Pulsar RöK, the borosilicate glass downstem replacement part is available in case the original downstem was mishandled or neglected. This certified replacement downstem for the Pulsar RöK Electric Oil Rig is made with durable borosilicate glass and features a disc style percolator.
Note: The small size is equivalent to the original glass downstem that comes with the rig. These work in combination with the original small sized glass jar base. The large size works in combination with the upgraded large sized glass jar base.
