The RAINDRIP INC R320CT is a 3/4-inch hose thread swivel adapter designed to connect a 3/4-inch threaded water source to 1/2-inch drip or irrigation tubing. The swivel design allows the fitting to rotate freely during installation, reducing kinking and making it easier to align tubing runs without twisting the line. This adapter is a standard component in low-pressure drip irrigation systems used in residential and light commercial landscaping. It is typically installed by irrigation contractors, landscape professionals, or experienced DIYers setting up zone-level water distribution.
This adapter is used at the point where a 3/4-inch hose bib, timer, or manifold outlet transitions to 1/2-inch poly distribution tubing. It is well-suited for garden beds, tree rings, and row drip layouts where a clean, leak-free connection at the head of each zone is required. Each package contains 10 units, making it practical for multi-zone installations or for stocking service vehicles.
Designed as an OEM-style replacement fitting for 3/4-inch hose thread to 1/2-inch drip irrigation system connections.
Installation is performed by irrigation contractors or qualified DIYers familiar with low-pressure drip systems. Shut off the water supply at the main valve or zone shutoff before making connections. Hand-tighten the swivel fitting first, then snug with pliers — do not over-torque threaded plastic fittings. Follow local plumbing codes and backflow prevention requirements where applicable.
