1. A swivel joint device comprising:
a first connector configured for attachment to a respective end of a first section of a vacuum hose;
a second connector configured for attachment to a respective end of a second section of the vacuum hose, the second connector being complementary to the first connector, such that the second connector is selectively engageable to the first connector, wherein the second connector and the first connector are configured for joining the second section and the first section of the vacuum hose;
at least one of the second connector and the first connector comprising a bearing, such that the second section and the first section of the vacuum hose are rotatable relative to each other, wherein the second connector and the first connector are configured for limiting kinking of the vacuum hose;
wherein the first connector comprises:
a first pipe, the first pipe being externally threaded and circumferentially complementary to an inner circumference of a respective section of the vacuum hose, such that the first pipe is selectively threadedly insertable by a first endpoint into the respective section of the vacuum hose for attaching the first connector to the respective section of the vacuum hose,
an outer flange fixedly attached to a second endpoint of the first pipe wherein said first pipe is inhibited from rotating relative to said outer flange, and
a first fastener attached to the outer flange;
wherein the second connector comprises:
a second pipe, the second pipe being externally threaded and circumferentially complementary to an inner circumference of a respective section of the vacuum hose, such that the second pipe is selectively threadedly insertable by a first end into the respective section of the vacuum hose for attaching the second connector to the respective section of the vacuum hose,
an inner flange positioned around the second pipe proximate to a second end of the second pipe, the inner flange being circumferentially complementary to the outer flange, such that the inner flange is selectively insertable into the outer flange,
the bearing being attached to the inner flange, such that the bearing is positioned between and the inner flange and the second pipe,
a ring selectively positionable around the second pipe, such that the ring abuts the outer flange, and
a second fastener attached to the ring, the second fastener being alignable with the first fastener, such that the second fastener and first fastener are positioned for being mutually engaged fixing a position of the first fastener and the second fastener relative to each other;
the first fastener comprising a plurality of first holes, the first holes being internally threaded;
the second fastener comprising a plurality of second holes, the second holes being internally threaded, wherein the ring is configured for rotating relative to the outer flange, such that each second hole is aligned with a respective first hole; and
a plurality of screws, each screw being selectively threadedly insertable into a respective first hole and an aligned second hole for attaching the outer flange to the ring.
