RegO issued a field advisory in early February to delivery personnel who might experience difficulties disconnecting from the L7579 filler valve on some ASME and Department of Transportation cylinders and containers. The company has since updated that advisory.

RegO determined that the seat disc on the upper check may not fully return to the closed position due to interference with the guide in the upper body.
