Abstract: A fluid coupling bracket adaptable for snap-on engagement with a coupling base. The fluid coupling bracket has tabs that engage with an annular groove of the fluid coupling base, and a plurality of teeth that set against radially extending ledges protruding from the external surfaces of the base and adjacent to the annular groove. The bracket has an extending flange portion having various size U-shaped recesses for fixing the bracket in supporting relationship with the fluid line.

Abstract: A check valve selectively prevents and allows fluid flow between an inlet and an outlet. An elongated housing has an internal fluid passage extending between the inlet and the outlet. The passage is defined in part by at least one sidewall extending parallel to a longitudinal axis of the housing. At least one stationary intermediate aperture is disposed between the inlet and the outlet. A reciprocal member is slidably received within the passage and carries a valve seat engageable with the housing to substantially close the intermediate aperture when in the first position and to substantially open the intermediate aperture when in a second position. The fluid flow passes straight through the reciprocal member along a linear path when the valve seat is moved away from the intermediate aperture. The check valve can be placed between an air pump and a manifold to prevent backflow of fluid from the manifold to the air pump.

Abstract: A fluid coupling including a coupling base with a fluid passage therethrough, and a rotatable fluid line supporting bracket. The bracket is adjustable depending on the direction of fluid line approach, and is fixable once a desired configuration is determined. The fluid coupling base includes an annular groove in which the pipe support bracket is rotatably engaged. The bracket may be fixed in position once a desired configuration is obtained, thus fixing the bracket in supporting relationship with the fluid line.

Abstract: A fuel filter nipple with a sleeve portion that fits directly into a fuel filter housing. One flange abuts and is brazed onto the housing. The nipple is formed of a tubular member with longitudinally spaced openings, one of which is larger than the other. One end of the sleeve portion defines the first opening, while the other end of it forms the flange which abuts the housing. The tubular member has a body portion extending from the flange to the other opening, as well as another flange located somewhere along the body portion.

Abstract: A fluid coupling including a coupling base with a fluid passage therethrough, and a rotatable fluid line supporting bracket. The bracket is adjustable depending on the direction of fluid line approach, and is fixable once a desired configuration is determined. The fluid coupling base includes an annular groove in which the pipe support bracket is rotatably engaged. The bracket may be crimped once a desired configuration is obtained, thus fixing the bracket in position on the coupling base to support the fluid line.
