Could you please tell me the diameter of the needle in on/off or bleed down valves?

I would like to use the high pressure seal in a custom design, but no vendor mention the diameter since it is standard.

Astaire, not sure what brand you are refering to but the Jet Edge Omnijet stye uses a .070" needle.

Please keep in mind these components are used for UHP systems and any modification can cause serious injury or catostophic failure.
