ABSTRACT:
A coupling assembly for a fluid circuit such as an irrigation system which facilitates removal of a valve or other component. The assembly includes a riser which is threaded at opposite ends with one end of the riser being engageable in the valve and the opposite end engageable in the internally threaded end of an adaptor. The opposite end of the adaptor is secured to a line in the fluid circuit. The coupling assembly may be disassembled by rotating the riser to retract it with the adaptor causing it to disengage from the valve or other component so the component may be removed and replaced with ease. The fluid circuit is re-established by oppositely rotating the riser to cause it to extend from the adaptor to bring it into fluid tight engagement with the valve or other component.
