Hose spec

[tiffer]

I need about 12 metres of macroline for a project,I've found some cheap locally but I need to now the spec of the hose we use.
I know it's 1/4" o.d but what is the bore size and the pressure rating,cheers.

we normally use 1/4" x 1/8" which is about the strongest imperial tube, and there's 1/4" x 5/16" which is the normal stuff.

Psi ratings are dubious, but should be up to 230psi.

The 1/4" x 1/8" is better and may hold 800psi

ID and working pressure varies according to brand. I know Parker parflex is 500psi Working pressure. Considering most HP tanks output somewhere between 700-950psi, that could be considered a bit low, although the burst pressure of the tube is obviously a lot higher.

Would be interested to know the supplier - as I've found it very difficult to locate trade supplies of air line and fittings in the UK (stupid american sizes on all paintball stuff, grrrr!)

I know of good sources for high pressure stuff.

1/4" x 3/16" is the rubbish stuff.

I'll give that a miss then that's the rubbish stuff I was offered...cheers for the info.
