[Towertalk] Teflon Tubing Source Needed

[Dennis Ashworth]

I am rebuilding a Hy-Tower and want to replace the reportedly inadequate 
top insulator sleeves with Teflon. This has been reported as a good 
solution to prevent arcing across the insulators on 160M. The dimensions of 
the existing insulators (material unknown) are 2" ID, 0.25" wall thickness 
and 4" long. Does anyone know where I can purchase a foot of Teflon tubing 
with the above dimensions?

Thanks
