HQMPCGarden Hose Quick Connect Brass Hose Quick Connectors Water Hose Connector 3/4" GTH (3 Female Coupler+ 6 Male )

Sent wrong set twice, Can you send me a set of nine that look like the ones in picture?

Are these compatible with Nelson brand?

Sorry to bother you but I have looked for replacement washers and can not find them. Can you give me a link? Thanks

How do you know if the connector is lead free? There is no marking on the connector itself. The lead free connectors appear the same as the standards
