The WellBoss Spacer Sub is used in Seal Assemblies and can be made-up in succession to suit the intended seal bore length; where there is a requirement for additional length without sealing capability, installation costs can be reduced by using compatible Spacer Tubes between the Seals Units, thus reducing the number of seal units required.

Spacer Tubes are available in a range of lengths to suit the application and seal bore configuration. Seal Assemblies can be extended or shortened by adding/removing sets of Seal Units.
