Default GPO Dial

Evening all. In some over enthusiastic restoration of a dial I managed to crush and shatter the little tube that is used as an insulator to jumper out speech ctt. on the phone on the dial contacts. I've put a circle around it in my picture.

Does anyone know what an earth it's called and where I get a replacement? I presume it's simply some sort of plastic tube I could cut to length? Or something?

Thank you.

Might sound a bit naff, but in the past I have used a bit of stripped wire sheathing cut to length in desperation.
Hope this Heath Robinsoness helps.

Thanks for the tips.

Just seems a bit odd to me that there isn't any info in the n-diagrams since the GPO seemed to be so good at documenting just about anything that moved.

'N' diagrams are the circuit diagrams of subscribers apparatus and ways of connecting it up. Adjustments and breakdown of components was always in TI's originally, then in EI's from c1930 then back to TI's c1969/70.
