Stop lid inflow in your existing manholes easily and economically. Our Lid Gaskets and Lid Plugs offer a low cost and maintenance option for sealing existing manhole lids.
Stop inflow through the lid by sealing unneeded vent and pick holes with our high quality rubber lid plugs. Various styles and sizes are available to fit your manhole lids.
Pick Hole Plug
Plug is 1/4" longer than it is wide to seal U-shaped side pick holes. Pick Hole Plugs can be removed with pliers for lid removal. Available to fit 1", 1-1/4", 1-1/2", 2", and 2-1/4" wide holes.
Style #1 Lid Plug
Can be removed with pliers for lid removal or to check interior manhole air quality. Available in six sizes to fit 3/4" through 1-1/2" diameter holes in lids 1" or less in thickness.
Style #3 Lid Plug
For use in rough or irregularly shaped holes or where easy removal is not desired. The tighter the nut is tightened, the more the rubber expands to the configuration of the holes. Available in five sizes to fit 1/2" through 1-1/2" diameter holes.
Manhole Lid Gasket
Stop inflow around the manhole lid with LID SEAL. This seal, molded and extruded from high quality rubber, is available either as a flat gasket or with our exclusive outside rib. It's use not only insures a positive lid-frame seal, but it eliminates lid rattle as well, and when properly installed, it is not disturbed by lid removal and replacement. Manhole Lid Gaskets are available in four widths, 1/2", 5/8", 3/4", and 7/8", and also can be purchased in either a fabricated size, or a 50 foot roll.
