orange duct in eng Bay

[lyle janke]

hi 

 does someone have a solution to stop the orange ducting used in the engine bay fraying /falling to bits on either end   . just a PITA

[skippydiesel]

 Possible solution; Hight Temperature Silicon Gasket stuff liberally rubbed in/around so as to bind the fibres. May have to put a stiff plastic tube in the end you are working on, so that you maintain the ID & round shape

 

Its not ducting , its insulating/heat/fire resit ant sleeve

I thought he was talking about air duct (SCAT tubing).

Only solution is a new piece. My observation in GA maintenance world is that it is quite durable. Make sure the hard pipes have no sharp edges. Support hose onto any fixed structure with silicone. Don't over tighten the clamps.

You could be right - we should await clarification 😆

 

Two more thoughts:

 

Paint on insulation stuff  - might be better as can probably be done in situ

Self annealing insulation tape - in situ application

 

If its SCAT the above two might just do the job  -

The method of repair depends on how you want your engine bay to look.

hi

my description seems to be confusing some of you  the tubing has a spring coil on the inside to stop it collapsing & a thread wound up the spiral on outside to maintain integrety of pipe . it connects the carbir to airbox & airbox to intake duct there is also a smaller Dia pipe supplying hot air to carby 

when it has been cut to length there is no terminnation of wire or thread leading to eventual soft end which is hard to push on pipe & then secure with hoseclip  see attach photo of pipe type i was referring to it may well have a more technical  name

wow that's nice and clean.  Consult your LAME , L2 or A&P for info .
dont worry about it. just ensure NOTHING is rubbing on it. 
It's not just random tube- it is high temperature, durable,  expensive sh1t

 

[skippydiesel]

Yeah!  SCAT tube can have messy ends - sort of goes with the product.

 

Still think one of my "possible" solutions may help  but in the end (😁)ts more of an aesthetic issue than a functional one.

[RFguy]

and any repair- consider what you do NOT want sucked down the pipe into your carburettor if it came loose.

[skippydiesel]

Self amalgamating tape , on the outside, then. Comes in a nice bright red or black - there may be other colours I am unaware of.

If you are experimental you could look at race car scat hose which is 1/4 of the price.
