Cracking tool

Minibulk relief valve cracking tool

The relief valve cracking tool has been designed to release the relief valve from the change adaptor without accidentally moving the check adaptor and causing a leak that requires product removal to repair.

Although these tools were specifically designed for use on difficult to access underground tanks, use on above ground tanks is also recommended.

4 Align the drive pins with the slots and slide over the flats of the relief valve.	5 Wind the actuating nut towards the arm.	6 Continue winding until the arms meet. Remove the tool and unscrew the relief valve	To ensure total safety use a Safe-Swap tool to prevent accidental valve ejection
