116M Monitor Probe Cap & 116 Monitor Pipe Cap
The OPW 116M Monitor Probe Cap is a standard 116 4" threaded pipe cap, drilled and tapped to accept a 3/8" or 1/2" wire grommet to secure an electronic tank gauge probe in a tank riser pipe. The 116M is gasketed for vapor and watertight service.
The OPW 116 Pipe Cap threads onto 4" riser pipes and provides access to ball float extractor fittings and underground storage tank bung openings. The 116 is constructed of composite Duratuff® to prevent rusting or corroding of steel riser pipes.
