A system for distributing fluids over a planar surface comprising a plurality of lengths of rigid perforate tubing and a plurality of fluid-tight articulated joints, each joint having an inlet port and a discharge port. The lengths of tubing and the joints are connected ad seriatim with joints interposed between adjacent lengths of tubing whereby the tubing can be arranged in accordance with the distribution pattern over a portion of the area. Each port of the fluid-tight joint communicates with a body element having a central bore and a peripheral flange. The flange of the inlet port mates with the flange of the discharge port so that the central bores fall into register with one another and the body elements of the respective ports communicate so that fluid introduced into the inlet port exits through the discharge port. A fastener is received in the bores for securing the body elements together while providing an axis for relative motion between the ports and a seal is sandwiched between the flanges and the bores for maintaining a fluid-tight connection while permitting the relative motion of the ports about the axis.
