ABSTRACT:
Disclosed are a hose fitting comprising the following and a process for manufacturing the same: A hose fitting body composed of a head portion with a through hole made in the center of a pair of flat surfaces thereof, a base portion, and a sleeve all of which are formed out of a test tube-shaped substance by a plastic deformation, and a nipple integrally fixed on the inner circumferential surface of the sleeve. The hose fitting of this invention provides the following advantages of offering easy work for the bending the base portion, offering readiness for securing a necessary cross-sectional area as the fluid delivery hole of the base portion even when the base portion is bent greatly, light-weighted construction having a uniform wall thickness and requiring less raw material cost, and fixing nipple on the sleeve inner circumferential surface in a fluid-tight manner without brazing or drive fitting the nipple.
