What it is

The Oso UK355030 is a 3 bar multibloc control unit. It is a combined inlet control assembly used with Oso unvented hot water cylinders, where it manages the incoming cold water supply at a set pressure. The unit brings the pressure reducing, expansion and connection functions together in a single component.

Before you order

  • Confirm the existing unit is rated at 3 bar and matches the Oso cylinder it serves.
  • Check the cylinder model and any markings on the current multibloc before ordering.
  • Have the part number UK355030 to hand when comparing against the unit fitted.
