I'm looking for a lightweight conduit for use in the wing to carry pitot static tubing and wing tip light wiring - probably 1/2 inch ID.  Main purpose is to allow for future wire replacement after the wing is closed.  Best I've seen is the slit convoluted stuff used in some autos.  Anyone got better suggestions?

Jim,

CPVC water piping. Inexpensive and light.

I used that very cheap milky white semirigid water pipe from the 

hardware store. Think it was high density polyethylene. Very easy to 

push wires through compared to corrogated stuff. Also more resistant to 

vibration as the corrogated stuff is intended to be somewhat flexible. I 

was advised to avoid any of the PVC's as they emit nasty toxic fumes and 

acids when they get hot or are exposed to flame...

The aviation department at your local home depot or lowes has plain tubing 

that I have used for everything from wiring conduit in the wings to 

pitot/static plumbing.



It's the milky colored stuff.......

hi jim,

 i know you wont get lighter than this. the 8' plastic tubes that make 

fluorescent tubes explosion proof. they even have a plastic fitting on each 

end that makes mounting slick.  i used one in my plane. they cut easy and 

can be spliced with pieces cut from an unused tube. they may not be stiff 

enough for your needs but were perfect for me.

Hi Jim- I used 5/8" CPVC on my RV through holes in the wing ribs- very happy 

with it and simple to add/remove wiring.  Not sure how it would work in a 

Europa though...

Hi Jim,

  In my 701, I too used CPVC.  I used 1 ".  And for routing around the fuel tanks, etc., I used, (don't laugh), 1" washing machine flex drain hose..the white stuff.  It mates perfect with the 1: CPVC.  My tech inspector loved it...

the cheapest and lightest i've ever seen is shower curtain rod wrap.  it's a 

very thin and light adjustable diameter tube (about 1") that is slit down 

the length.  they were a $1 last i saw, in maybe 5' length.

Jim,

        Try going to the local builders supply and getting  a roll of

sprinkler supply tubing.  Mine is black and the wall is thin and light. 

I'm using it to run to the wing tips for lighting and pitot tubing.  If

you need to make a break in the middle do it at an inspection plate.

For what I feel is a better alternative, try:



http://www.usplastic.com/catalog/product.asp?catalog%5Fname=USPlastic&catego

ry%5Fname=78&product%5Fid=4905



If that doesn't work, go to www.usplastic.com and search for Tenite Butyrate

tubing.



It is the thinnest wall rigid tubing I've found, and it is available in many

sizes.

Hi Jim-



Re:  I'm looking for a lightweight conduit...probably 1/2 inch ID...Best

I've seen is

the slit convoluted stuff...Anyone got better suggestions?



Van's aircraft sells the same stuff, only without being slit.  IIRC, it is

about 7/8 dia.  When I installed mine, I took a handy scrap of 3/8 dowel

about 2 inches long, rounded it's shoulders, drilled a transverse hole

through it, and tied a length of heavy kite string to it.  The string is

just over double the length of the conduit.  I used my blow gun to launch

the dowel segment down the conduit.  I had reservations about the dowel

passing through the corrugated, ill fitting, flexible (read:  not quite

straight) tube, but figured worst case, I could pull it back out with the

string.  



Well.    The dowel, with the string in tow, shot through the conduit, out

the other end, across the shop, and bounced off the far wall.  For the

second attempt, I held the free end of the string  ; - ) and all was well. 

I then installed another toggle / dowel on the free end of the string. 

This allows me to tape a wire to the string near it's mid point and pull it

through the conduit.  I plan to leave the strings and toggles in the

various conduits for future use as fish tapes.



Perhaps not a perfectly elegant solution, but entirely effective and of

negligible weight!

A similar approach to the dowel is to tie the string around a cotton 

ball and suck it through the conduit with your shop vac.  Make sure you 

tie off the end of the string or you'll have to get it out of the shop 

vac and try again.  Works with all sizes of conduit and you don't have 

to worry about shooting hard wooden objects around the shop
