What size tubing for a 3/16 flexshaft with teflon?

[JCAustralia]

Hi guys

what size tube are you using for a 3/16 flexshaft with teflon?

OSE store recommends 9/32 size. I have one and I find it very hard to slide my teflon tube in it.

I'm thinking of using one size up (5/16 size)......

Is that ok?

Thanks

9/32" is the correct size tube, I had some Octura teflon liner that was very tight to the point that it would never go in so contacted the supplier id got it from & he said to stretch the liner out which reduced the o/d down & it did then go in ok. Martin.
