Brass Exspansion Garden Hose Coupling

These are the Coupling / Garden Hose Specification that we are looking for.
Please let me know if your company already produces to these specifications. Or if you have anything simmilar in which you can send a picture or drawing.

1) In the USA we manufacture to a "National Hose" standard which is 3/4
inch by 11.5 threads per inch (pitch).

2) The couplings are made of brass alloy 260 (70% copper, 30% zinc)

3) We manufacture these fittings and are looking to import ones of equal quality and lower cost.

4) We would be looking at a first shipment of complete Lawn and Garden Hose Couplings, specifically Male and Female Expansion Couplings and ribbed Ferrules
