Underhill International offers a series of pressure-compensating bubblers for low-volume irrigation. The pressure-compensating bubblers are available for use on planting beds and shrubs. They feature a self-sealing design that allows them to be installed without thread seal tape, saving time and material. They provide full-circle coverage and allow water output to remain constant, even with input pressures from 5 to 60 psi. The bubblers are available in two models, pre-set flow and adjustable flow.
