ABSTRACT:
A T-shaped connector for use in automotive radiator cooling systems, in which each nipple is radially enlarged to form a substantially frusto-conical obverse taper, an apex, and a substantially frusto-conical reverse taper having one or more shouldered steps cut into it. The height of the apex is determined as a function of the elastic properties of the rubber hose to be connected to the coupling, a rubber hose is slid onto and over the radially enlarged portion, and a substantially frusto-conical ring is seated onto that portion of the hose fitting over the reverse taper of the nipple.
