The Chinese made nozzles for nozzles on the models of Rainbird or Hunter nozzles.

I ordered a sample of 7 different nozzles because often it is sold in the same size.

My conclusions are as follows:

• Light green: 4 YEARS: 1.2m
• Blue: 6 YEARS: 1.8m
• Brown: 8 YEARS: 2.4m
• Red: 10 YEARS: 3m
• Dark green: 12 YEARS: 3.6m
• Black: 15 YEARS: 4.5m
• Grey: 17 NA: 5m

For the record:

• 2 Grey 17 AN (with an additional connector?): €2.80
• 20 Brown 8 YEAR: 25.49€
• 20 Grey 17 YEAR: €25.49
• Per 50, all sizes : 48€
