发明名称 Valved couplings for RV sewer hose
摘要 The sewer hose for a recreational vehicle includes a valve coupling disposed at both ends of the sewer hose so that the body of the sewer hose may be closed off after the sewer hose is used to empty the holding tank of the recreational vehicle. The valve couplings and sewer hose have exterior dimensions small enough to fit in the standard sewer hose storage compartment.
