Abstract
A hose fitting body composed of a head portion with a through hose made in the center of a pair of flat surfaces thereof, a base portion, and a sleeve is formed out of a test tube-shaped substance by plastic deformation, and a nipple is integrally fixed on the inner circumferential surface of the sleeve. The hose fitting allows for the bending of the base portion while securing a necessary cross-sectional area for the fluid delivery hole of the base portion even when the base portion is bent greatly. The light-weight construction facilitates uniform wall thickness while reducing raw material cost, and provides for fixing the nipple on the sleeve inner circumferential surface in a fluid-tight manner without brazing or drive fitting the nipple.
