摘要： A tubing to supply diesel exhaust fluid to an exhaust system of a diesel engine includes an inner layer made of a first material and an outer layer made of a second material. The first material includes polyethersulfone polymer or polyphenylene sulfide. The second material includes a polyamide or polyphthalamide. An outer surface of the inner layer and an inner surface of the outer layer include a reactive material that facilitates bonding between the inner layer and the outer layer of the tubing.

摘要： A hose assembly includes a first conduit, a second conduit, a nozzle assembly, and a valve assembly. The first conduit defines a first fluid path through the hose assembly. The second conduit is received within and extends partially through the first conduit. The second conduit defines a second fluid path through the hose assembly. The nozzle assembly is coupled to a first end of the first conduit. The valve assembly is fluidly coupled to the first conduit and the second conduit. The valve assembly is fluid coupled to a second end of the first conduit opposite the first end. The valve assembly is adjustable between a first position and a second position. In the first position, the valve assembly provides water into the first conduit. In the second position, the valve assembly provides pressurized air into the second conduit.

摘要： A modular fluid spray nozzle is constructed from an inner conduit, having a sidewall with a center hole, housed inside a center conduit that includes a window defined by a sidewall, and a flexible or rigid outer conduit wrapped around the center conduit and forming a chamber with the rectangular window. The chamber is in fluid communication with the center hole and with at least two apertures defined by the outer conduit. The inner conduit is configured to be coupled to any type of conduit material, such as PVC pipe or another modular fluid hose segment.

摘要： A pipe coupling for triple wall corrugated plastic pipe includes a triple wall corrugated bellmouth connector that is of a unitary construction with one end of the corrugated plastic pipe. This bellmouth connector is of higher strength and in cooperation with the two wall corrugated spigot provides a high strength coupling. This coupling includes the bellmouth connector and spigot that are made inline with the corrugated pipe. A method for the manufacture of the pipe includes controlling of an air pressure on the outside of a formed two wall corrugated pipe as an exterior third wall is secured thereto.

摘要： A hose having an observed color, the hose includes a tubular wall having an interior, an exterior and a thickness. The observed hose color changes between a first hose color in a first state and a second hose color in a second state. Differences between the first state and second state may be the result of different expansions of the hose, different pressure pressures within the hose, differences in amount of fluid within the hose and different tensions states for the hose. Observed color changes between the first state and second state may be a color change, a color shade change, alternating rings of at least two different colors or shades of color along the length of the hose, a color pattern change or even the generation of indicia on the hose.
