the mob that Lozza listed for the tap, sell the die's as well. I'll see how much they are locally first.

I have a thread file if you change your mind - welcome to borrow it  ;)
Looking for YZ250C parts NOS if possible

Thread files work a treat as when you file the damaged thread it has the correct pitch but the 'hills and valleys' on what you have filed are under the root diameter.So anything screws on very easy because of that. The files have a part on them for internal threads also

Here's another solution .... buy an M & F adpt of same thread in brass  use PERMABOND or LOXSEAL to bond. The brass  fitting will have a longer FI thread - thus engaging threads that are not damaged.

is there enough thread left to cut some of the stripped section off and then file/machine the spigot flat again for the seal/fibre washer to do its job?you can make a mandrill to suit a cutter sold seprately to suit those oring style tap washers,the cutter cost about $13 and a machined mandrill wouldnt be much

well, I picked up a thread file, cause I figured it was something I could use again, whereas a die would be a one-off. Sorry Lozza, I thought you were having a lend when you first posted it, I'd never seen one before and figured it was like the "wankometer" tm you found on ebay. ;D

It certainly made things better, whether there's enough thread there now I'll  have to find out when I test fit before painting.

Otherwise, Stu's plumbing repair idea might come into play.

I don't quite follow this Matt, I picked up what you're saying about cutting the spigot shorter and resurfacing it, but the Mandrill bit is over my inexperienced head ???

I have used neat little 1/4 " (also 3/8 and 1/2) inline mini ball valves in nickel plated brass with a plastic cock handle and a hex body which you could use to adapt with the appropriate brass bushing. These wont break the bank at around $5-10 from Blackwoods. I have used these before and they are a quality peice of kit. You could also turn it 90 degrees out of the tank for a neater, less obvious installation.
