Coreliners are rigid, transparent PVC tubes with a wall thickness of approximately 1 mm, that fit snugly inside the core barrel inner tube.

Coreliners can be supplied to fit most types and sizes of core barrel - metric, DCDMA and wireline. It is normally supplied in standard 5-10ft lengths, with or without plastic end caps.

To use the coreliner system a modified Core Bit and Core lifter is required with reduced internal diamete. This is to ensure that there is adequate clearance for the core to fit into the plastic coreliner tube. Such "coreliner set" bits and core lifters are available on request.
