Claim:
An irrigation connection system comprising: first and second pipes for flowing a fluid; one of said first and second pipes having a female fitting in fluid communication with the one pipe, said fitting having straight, non tapered female threads; the other of said first and second pipes having a male fitting in fluid communication with said other pipe, said male fitting having an external straight, non-tapered thread and a cylindrical section spaced axially from said external thread; said male fitting being receivable in the female fitting with the male and female threads engageable with one another to connect the fittings to one another; a cylindrical gasket between said male and female fittings and spaced axially from the male and female threads upon connecting the fittings to one another; the male cylindrical section and the female fitting engaging said gasket when the fittings are connected to one another to seal the fittings to one another thereby to establish fluid communication between the first and second pipes; said female fitting having an opening adjacent one end for receiving the male fitting, the gasket being located on the female fitting on a side of the female threads remote from the opening; said male fitting having an opening on one end for communicating the fluid between the first and second pipes, the male thread being located on the male fitting an axial distance from the male fitting opening at least equal to an axial distance between the gasket and a first of the female threads adjacent the female fitting opening thereby enabling the cylindrical section of the male fitting to seal within said gasket of the female fitting upon initial threading engagement of the male and female threads with one another.
