7mm tube and 9/32 OD are they the same

[sigelitest]

I got a set of 7mm brass tube for my H&M build and I have folded and kinked it till I gave up. This has been the only size tube I have had a problem with. I have tried heating it and even tried using a tube bender. Is the 9/32 size tube close enough to interchange. I am hoping it is a little thicker wall. I ordered some from OSE.

I dont have a local Boat HS so when i screw sumpin up i wait a week

9/32" is only around 6 thou larger than 7mm. Ive found with some of the metric tube they supply with hulls that its very thin walled indeed & dosnt take to bending well at all. The K&S tubing is thicker wall generally than some of the rubbish stuff they put in kits or hulls.

9/32 = 7.14mm

i am thinking i can use the same teflon liner? i don't know what the ID is on the 9/32 tube

If its K & S 9/32" od tube then its 1/4" id. if the teflon liner dosnt go in just get some Octura liner.

cool thanks the .187 flex will fit ?

OK i got the 9/32 tube and it is no problem to bend but the liner don't fit
the OD on the the 9/32 is larger than the 7mm tube but the ID is smaller on the 9/32 tube
i plan on orderig liner for the 9/32 tube.. will the square 3/16 flex from fightercat fit in the liner or will it be too tight.
I am wanting to continue my build but i don't want to install the 9/16 tube till i know it will work.
