The emitter shall be cylindrical in shape and provide surface area for filtration throughout 3600 of its outer circumference. This increased filtration surface area shall assure that the water that enters the inline emitter can always come from the upper half, or cleanest part of the flow path in the polyethylene tubing regardless of how the inline tubing lays on the ground. c. Rain Bird Landscape Dripline tubing shall be brown in color and conform to an outside diameter (O.D.) of 0.630 inches (16 mm) and an inside diameter (I.D.) of 0.540 inches (13,7 mm) and wall thickness of 0.045 inches (1,1 mm). d. Rain Bird Landscape Dripline shall have factory installed, pressure -compensating, inline emitters installed every [12] or [18] or [24] inches. OR e. Rain Bird Landscape Dripline shall have factory installed, pressure -compensating, inline emitters with spacing as indicated on drawings. f. The flow rate from each installed inline emitter shall be a consistent [0.6] or [0.9] gallons per hour when inlet pressure is between 8.5 and 60 psi (0,7 to 4,1 bars). g. Operating pressure range: 8.5 to 60 psi (0,7 to 4,1 bar). h.. Models: per plan III FITTINGS A. Compression Fittings 1. Easy Fit Compression Fittings: a. The Easy Fit Compression Fitting System shall consist of 3 fittings (tee, coupling and elbow) plus 5 adapters and two removable flush caps. b. The Easy Fit Compression Fittings shall accept all polyethylene tubing from .630" to .710" (16mm-18mm) OD and shall provide a leak -free compression fit. They also shall provide connections to threaded components when used with any of the 5 adapters. The fittings shall be molded from UV -resistant ABS material with a Buna-N rubber seal for long-term, leak free connections. c. The adapters shall be made of UV -resistant ABS materials and shall only be used with Easy Fit Compression Fittings. The adapters shall be installed in the Easy Fit Compression Fittings and threaded onto'/" or %" Male- or Female -threaded components. Pressure loss for the Easy Fit Adapters is a maximum of .1 PSI for each adapter used. d. The removable [black] or [purple] flush cap shall be used to close off a line. The purple flush cap shall be used to close off a line containing non -potable water. e. The operating pressure range for the Easy Fit Compression Fitting System shall be 0 to 60 psi (0 to 4,1 bars). f. Models: L Tee: MDCFTEE ii. Coupling: MDCFCOUP iii.
