What are External Divided Sleeves?

The External Divided Sleeves are a two-piece split sleeve system that can be retrofitted around an existing pipe or cable to either side of a wall/bund. The Link-Seals are then installed to provide the permanent seal.

The External Divided Sleeve can be used in conjunction with the Link-Seal System to solve difficult pipe penetration challenges.

The External Divided Sleeve offers complete protection when the annular space is too small, when the core isn’t exact or doesn’t align with the pipe or cable. The base plate can also be customised during manufacture to ensure that it is anchored and sealed to the substrate securely.

The External Divided Sleeves are manufactured from S-304 Stainless Steel and come complete with all bolts, nuts and the appropriate rubber gasket that seal against a variety of chemicals like fuel, oil, water and gas.
