3/8 Tubing – Black (250′ roll)

NOTE: 3/8-inch tubing is primarily used only for pressure boost lines on industrial/commercial installations and very large residential installations. It’s also used for connecting the Gen 3+ tankless units to the water hose bib. Tubing that is used to connect nozzle fittings together is typically 1/4-inch diameter tubing. 

Our 3/8 tubing is also available in 25-foot roll, item 10378.
