Abstract: Improved couplings for conduit systems include a male coupling and a female coupling. The male coupling and female coupling may be mechanically engaged by inserting the male coupling into a receiver in the female coupling until fastening structures are aligned, and then rotating one or both of the male and female couplings until the fastening structures are overlapping and in interfacial engagement. The male and female couplings provide an efficient coupling solution for end-to-end conduit connection and also addresses a leakage problem in conventional irrigation pipe couplers.

Abstract: A pipe coupling has two segments with angularly oriented action surfaces in facing relationship. The action surfaces induce relative rotation between the segments when the segments are drawn together to engage the pipe elements being joined. Attachment elements on each segment, in the form of lugs, accommodate adjustable fasteners which draw the segments together when tightened. Angularly oriented support surfaces on the lugs engage one another and react the fastener force. Stop surfaces are positioned on the lugs adjacent to the support surfaces. Engagement between the stop surfaces limits the relative rotation between the segments.
