351A Extension Hoses
Overview
The 351A Extension Hoses allow gas sampling from difficult-to-access locations like manholes and storage tanks. They securely attach to the inlet of GV-100/GV-110 sampling pumps and enable accurate downward measurement at a distance. For twin-tube configurations, additional accessories such as guard rubbers (No. 358 and No. 359) are available. Note: these hoses are not compatible with Oxygen Detector Tube No. 31B.
