Well Caps Reduce Gas Leaks

(Q.E.D. Environmental Systems)

Q.E.D. Environmental Systems’ Stabilizer landfill gas (LFG) well cap features a unique, patented support ring molded directly into the cap that aligns and stabilizes the LFG wellhead and reduces leaks. The well cap’s durable, heavy-walled polyethylene construction makes it viable for any climate.


According to its maker, the Stabilizer is the first engineered gas well cap that allows liquid level readings without removing the wellhead. Easy access for liquid level reading is faster, safer, and results in less system disruption. There is no air introduction or gas release, no need to shut down the well for level measurements, and no need to rebalance the wellfield afterwards.


The cap’s support ring design takes pressure off the flexible coupling and the flex hose and, along with watertight threads, reduces the potential for leaks at the wellhead. The caps are molded in distinctive yellow to help identify and protect the entire well from damage and ensures users are receiving genuine QED well caps.


The Stabilizer LFG well caps are designed to work with 6-inch and 8-inch diameter wells with 2-inch or 3-inch gas wellheads. An economy model is available for 6-inch gas-only wells. All well caps feature direct access ports compatible with several existing landfill products. Available pump fitting kits allow conversion of gas recovery caps to dual extraction wells.
