Galvanized steel 10 gallon back bosh and tue iron assembly
 
Our galvanized steel 10 gallon back bosh and tue iron assembly can be used to replace old cast iron tue irons which have burnt out and are guaranteed for 2 years. The air pipe protruding from the back of the bosh has a short 1" BSP pipe thread to allow easy connection of air pipe. All flanges are sealed with a high temperature gasket sealant to ensure no leaks. We fit a drain plug in the bottom of the bosh for annual maintenance.
