OK. We all know that 1/4 inch tube is the norm here but why? During the rebuild of the Rocket I asked this same question after running across some really slick 1/8 inch pneumatic tube and push lock fittings from MSCdirect.com. Its been flying for a few years now with zero issues. What factors am I failing to consider in this application? More probable icing and clogging due to the very small ID of the tube?
From an installation standpoint, the spaghetti thin 1/8 stuff is a snap to route and bundle - hardly thicker than #12 AWG wire. See the pic below for a comparison to the norm.
This stuff is rated at 800+ PSI burst strength, so PLENTY capable for the pitot system.
As an aside, I'm also using 1/8 (stainless steel) tube for my brakes. MUCH easier to fabricate and route and I see zero difference in performance.
Not an endorsement per se', but food for thought with real world experience.
