While we all discuss fuel and oil hose it seems like a good time to ask what folks are using for fire shields over these hoses? Some of the products advertised by the aviation suppliers seem very expensive and it would be great if there are some good yet less costly alternatives out there.

Sometimes in aerospace materials,



you get what you pay for!



Firesleeve is just such a time

Depending on where and what size you buy fire sleeve can be $3-$5 per ft. All the fuel lines and oil lines in an engine compartment should be sleeved. The sleeves should have clamps on each end and they should really be dipped in a fire sleeve sealer like "End Dip". This keeps the sleeving from wicking up fuel or oil inside the sleeve to burn. That stuff is about $150 a quart. These fire sleeves depending on what you buy are good up to 2000 degrees. You are never thankful to have something that protects you until you need it and it has never happened to me before until the first time.



As a 28 year fireman I wish I had a quarter for every person that said "That has never happened before".

I bought and still have some of the aeroquip firesleeve, you can tell just by looking at it that it's great stuff.



But it does look like for it to be effective you have to install it right, preferably with the ASTM compliant fittings on the ends and with it clamped at each end with the little spring like clamps.



Just running it over the lines and leaving the ends open (like I have on a couple runs of my fuel line as sort of insulation) is probably almost like not having firesleeve on there at all....



So I basically probably wasted my money unless/until I go with a correct installation (which is on my to-do list).



There's a video on Youtube of (Brian?) Carpenter installing the firesleeve over an Aeroquip fuel line. the finished product looks like it'd withstand nuclear weapons......

Lucien,



Firesleeve without antiwicking end dip is not worthless at all.



It protects the hose from chafing and from heat quite well. The only

thing the end -dip process is for is to prevent flammable liquids from

wicking into the fiberglass mat.  If you already have flaming gasoline spraying around your engine bay, then a little extra flame will not matter.



Nonetheless, antiwicking is easily and inexpensively done:



If you want to anti-wick any non-certified a/c, then the red heat resistant

silicone caulk works just fine.



Also, the band clips can be replaced with standard stainless screw-driven

compression clamps.

Re: fire sleeve end-clamps - Home Depot sells stainless steel "Tywraps".

Compared to the regular fire sleeve end clamps you don't need the special

installation tool (e.g. Spruce 05-00447 or 12-00684). Don't know how they

compare to the approved clamps but if stainless is melting under my cowl I

think I have bigger worries.

Ah yes, the aluminum block of the engine will melt far below the

temperature at which stainless will go soft.



I have not seen the home depot wraps, but I'll bet they are even

nastier to probing fingers than nylon!

Several decades ago, I wired industrial control panels for a living and used nylon zip ties by the hundreds. We used a "hand gun" shaped tool that both tensions and cuts flush the tail of the zip tie so there is nothing sticking out to grab a wayward piece of flesh.



I found a "good enough" quality one at Harbor Freight. It probably would not stand the abuse that the pro quality ones do but I've used it on many dozens of zip ties and it works well and will will probably last for the rest of my zip tying life. It is intended for nylon and plastic zip ties, not the SS ones, which I've seen but never used.



This first one is junk. Don't buy it.

This one looks very similar to the one I bought which works well.

Harbor Freight sells stainless steel tie wraps that work real well for banding the fire sleeve. A pack of a "million" was very reasonable compared to the few you get in a packet at the auto parts store for attaching exhaust wrap. It certainly does a nicer installation than hose clamps and you don't need a banding tool. I will be using them to band my exhaust pipe wrap.

 Actually Ira,they are not. You just clip off the extra length and then use your needle nose pliers on the cut end to roll the end.This tightens it a bit more and no sharp edges like a regular tie wrap.

OK!



What department of home Depot??



BTW,  I've been using a flush cutting mini-dykes for the past three

decades and have not been sliced by one of my own since.

What I found works well is to have a piece of sandpaper in your pocket to

lightly buff the end of the cut off tie.  Better than that is to use

Coraseal and waxed string.

I found them in the electrical department with the conventional Tywraps.

Thanks much for all the great information. I will stick with the quality fire shield but go with the SS Tie Wraps. Thanks again.

OK,



Could not find the SS tie wraps at HD and none the sales personnel

were familiar with them.

OTOH, I did find them at Loews!  They were roughly 10 for $5.00 for 6"

wraps.  I put two on my firesleeved fuel lines: worked fine, but took a

big dykes to cut the excess!!
