Abstract: An adjustable gas/air feed assembly for a gas burner having a gas conduit section and an aspirator section mounted for telescopic sliding movement relative to the conduit section. The sections are held at a desired telescopic extension by an adjustable seam carried by the inner section of the assembly, the seam being effective to circumferentially close the inner section while permitting limited radial contraction thereof. The inner section can thus be biased outwardly against the outer section of the assembly for holding the sections at a desired extended position.

Abstract: A flexible plastic conduit having a pair of longitudinally extending reinforcement tapes to improve the resistance to elongation of the flexible plastic conduit is provided. A fitting is also provided to cooperate with the flexible tubing to provide the proper resistance to forces trying to separate the flexible conduit and the fitting when in assembled relationship. A method for assembling the flexible conduit and the fitting is also provided.
