The RAINDRIP INC R333CT is a 3/4-inch pipe thread swivel by 1/2-inch compression tee fitting designed to connect a threaded pipe fitting to 1/2-inch poly or irrigation tubing at a tee junction. The swivel inlet allows for easy hand-tightening without twisting the supply line, while the compression outlets secure 1/2-inch tubing without solvent or solder. This fitting is used in low-pressure irrigation and water distribution systems. Plumbers and irrigation technicians install this type of fitting during system layout or repair. Each package contains 10 fittings.
This tee fitting is suited for residential and light commercial drip irrigation systems, lawn sprinkler laterals, and garden watering setups where a threaded water source needs to branch into 1/2-inch poly tubing runs. The compression connection style makes it practical for field installation without specialized tooling. It is appropriate for above-ground and shallow buried irrigation mainline and lateral assemblies where 1/2-inch tubing transitions from a threaded supply point.
Designed for use with 1/2-inch irrigation tubing in standard drip and low-pressure irrigation systems where a 3/4-inch pipe thread supply fitting is present.
Shut off the water supply and relieve line pressure before disassembling any existing fittings. The swivel end threads onto a standard 3/4-inch male pipe thread fitting and should be hand-tightened then snugged with pliers — do not overtighten, as overtightening can crack the fitting body. Compression ends require that tubing be cut cleanly and squarely before insertion to ensure a leak-free seal. Follow local plumbing code requirements for irrigation system backflow prevention and burial depth.
