What it is
The Oso UK214005 is a 6 bar expansion relief cartridge manufactured by Oso. It forms part of the expansion relief valve arrangement on Oso unvented hot water cylinders and their associated control components. The cartridge regulates the pressure at which excess expansion water is discharged, protecting the cylinder and its fittings from over-pressure.
Before you order
- Confirm the existing relief valve is rated at 6 bar and that the cartridge thread and body match the valve in situ.
- Check the cylinder's installation and servicing documentation for the specified relief pressure, and confirm the cartridge is the correct service item for that valve body.
- Have the cylinder de-pressurised and drained down as required before removing the existing cartridge.
