20mm plastic male bush (long)

[ekmdgrf]

Anyone know where one can acquire a long 20mm plastic male bush?

They all seem to be a fairly standard size:

I'm after one a little longer. I've been able to locate long brass bushes but not plastic. Anyone know of any?

Pedant preemption: 20mm is the diameter. I'm talking about the length. I'm not looking for two different sizes of 20mm

I can only find brass too. Is it a big no-no to have brass?

you can make similar to one by cutting a female adaptor or cut off just the thread and use two lockrings
