Abstract

A tubular part is provided for a household appliance and includes a portion for operating with fluid. A check valve formed with an elastically compressible hollow cylindrical insertion body is inserted in the tubular part, which is configured as a receiving part and comprises a fluid passage and a contact region serving as a valve seat, the insertion body at the end thereof opposite the contact region of the fluid passage carrying a sealing element. Due to the insertion body being elastically compressed in the receiving part and thereby fixed in the axial position, the sealing element rests against the contact region such that fluid passage is possible only in the direction from the receiving part to the insertion body, while the opposite direction is substantially blocked.
