What it is

The Oso 550853 is a temperature and pressure relief valve manufactured by Oso. It is a safety component that opens to discharge water if the stored water in a cylinder exceeds its temperature or pressure limits.

Before you order

  • Confirm the part number on the existing valve or cylinder documentation matches 550853.
  • Check that the valve is listed as temperature and pressure relief rather than a pressure-only relief valve.
  • Verify the connection size and thread form on the existing valve before ordering, as these are not stated in the supplied product data.
