To improve inserting facility into a piping member and slip-out preventing property from the piping member by forming the inner circumferential faces of the terminal end parts of a hose for low pressure piping into recessed and projecting parts, in a hose for low pressure piping to be fitted to the outer circumference of the piping member, and fixed by fitting a hose clamp to the outer circumference of the part to be fitted.

When a hose for low pressure piping is manufactured, at first the one end side terminal part of a non-vulcanized rubber hose 3 is inserted between the receiving part socket 41 and the receiving part nipple 42 of a receiving part 4. Next, a mandrel 5 provided with a mandrel socket 51 and a mandrel nipple 52 is inserted from the terminal part on the other end side of the non-vulcanized rubber hose 3. After these are vulcanized at high temperature, by drawing out the receiving part 4 and the mandrel 5, the hose for low pressure piping in which the inner circumferential faces of terminal parts are formed into recessed and projecting parts is provided. By such hose for low pressure piping, inserting facility into the piping member and slip-out preventing property from the piping member of the hose for low pressure piping can be improved.
