Manual indicates to see page 2 for model information including maximum working pressure and approvals. This appears to be a thermal relief kit component. The manual notes that thermal relief kit selection may need to change from application to application depending on pump air operating pressure and fluid working pressures of system components. Kit includes bung adapter that threads into tank cover bung, coupled hose, and 90° swivel adapter. Installation requires thread sealant and manual pressure relief before installation. The two hose connections should be positioned on the same side of the pump lower to prevent hose wrapping.
