Rain Bird has put together the Easy Fit Fitting and Adapter system, a simple-to-install system that centers around Easy Fit Compression Fittings. They are compatible with any manufacturer’s 1/2" tubing with outside diameter (O.D.) ranges from .630" to .670"(16 mm to 17 mm). Complete system of compression fittings and adapters for all tubing connection needs in a low-volume system. Reduces inventory costs: Multi-diameter compression fittings work with a wide range of 1/2" polyethylene tubing sizes (0.630" to 0.669" or 16mm - 17mm outside diameter). Saves time and effort: 50% less force is required to connect tubing and fittings versus competitive compression fittings. Adapters swivel for easy installation. Provides increased flexibility: Just three Easy Fit Fittings and five Easy Fit Adapters are needed to make over 160 combinations of connections, accommodating countless installation and maintenance situations.

Step 3 After selecting the right Easy Fit Compression System components, simply assemble the two using little effort. Step 4 Easily insert any manufacturer’s drip tubing from .630" to .669" O.D. (16 mm to 17 mm) into the fitting and connect onto the threaded component. Simple. Fast. Done. Specifications: Flow Control: 0-6 GPM Pressure Rating/Range: 0-60
