Negishi watering can rose diameter

[Matt3839]

Was wondering if anyone knows the inner or outer diameter of the Negishi industries watering can rose for No6 or No4? Specifically the pipe leading to the rose/head.

I’m trying to get a more gentle rose for my Onoe seisakusho 8L can and hoping maybe Negishi industries rose will fit.. but I’ve not found much info online or their website. And unfortunately Onoe Seisakusho doesn’t sell rose separately from what I’ve found.

I've got a No.6 Negishi watering can and I measured the pipe leading into the rose for you.
The diameter of the pipe is 1.35cm (0.53 inch).
