ABSTRACT:
A convoluted hose construction is provided and comprises an elongated elastomeric strip having a base and first and second connecting members extending in the same direction from the base with the first connecting member extending from a central part of the base to define a lateral extension of the base outwardly of the first connecting member and the second connecting member extending from an end portion of the base. The strip is disposed in a helical pattern with the first and second connecting members connected to define the hose construction having a plurality of helical turns defining alternating crests and troughs and the lateral extension cooperates with the base to provide the hose construction with a substantially smooth inside surface even with the hose construction extending in a curved path.
