Abstract
A swivel fitting includes a first annular member and a second annular member. The first annular member has a second end which is threaded and a first end which receives the first end of the second annular member. The second annular member has a second end which is received within a tube or hose. The members are coupled together by expanding a frusto-conical end section of the second annular member within the first annular member, so that a radial lip on the frusto-conical section seats within an annular grove formed within the first annular member. The swivel fitting is sealed with an O-ring which is sandwiched between the radially extending stop on the first annular member and a shoulder on the second annular member.
