Exhaust wrap kit

[Don Moyer]

We just added an exhaust wrap kit to our product line.

Each kit includes 15 feet of 2" wrap and two end clamps. The wrap is 1/16" thick and is usually sufficient to cover 4 to 5 feet of the 1-1/4" piping commonly used in constructing the hot section of an exhaust system. When the wrap is used so that there is approximately 1/4" of overlap, the temperature radiating from the pipe is reduced by 50 to 60 %. When a pipe comes within close proximity to a cockpit floor or other structure, the wrap can be used in two layers.

Hi Don, so is this for use in wrapping the flexible exhaust hose portion?

[Baltimore Sailor]

No, this is for wrapping the hot pipe section. By the time the flexible rubber exhaust hose starts, the water injection has lowered the exhaust temp.

It's used to wrap the HOT EXHAUST section.

Jerry,

I like the design of this system, can you tell me how you hooked up the exhaust water hose

Moyer Product No. - EXHT_01.1_324 - can be found on this page.

I made my own little "injection port" when I cobbled up my hot section. A standard black iron "T" with an adapter bushing and a hose barb.

Exhaust Hot Section Temperature

Don's tape is rated for 1400 F so I'm wondering what is the actual temp of the hot section. It would be good to know this as there are lots and lots of posts here from folks wondering what thread sealant should be used. I find lots of recommendations about what has been used but no one answers the question: what is the top-end temperature off the exhaust manifold.

[roadnsky]

I've shot temperatures at the top of my hot exhaust rise at 500°

[jimmoser]

500

That would be 500 outside the tape right? Given the tape insulation, the temp on the actual pipe would be higher.

The temp of my exhaust flange was 550. The engine was warmed up and running at 1500 rpm, no load.

I used an infra red gun. Nothing covering the flange.

No thread sealant should be used on a pipe hot section. It will rust and carbon itself together nicely, and should be completely replaced when necessary.

Agree completely...pipe thread seals when tightened. There is a possibility of a drip if you do not (or cannot) bring those pipes tight in the orientation you want your hot exhaust to lay. Normally you can work it, with two good pipe wrenches, and seal the whole thing piece by piece in the orientation you want.

Thread Sealing

In my case the orientation just doesn't work. On one fitting, fully tightened is about 90 degrees past where the pipe is correctly aligned so more than a drip is involved. There are two other fittings that also leak but not as badly.

I need to consider a second best solution: a thread sealant. Most sealants available at retail are rated to about 400 degrees. I expect what will happen is that the sealant will hold back any leaking while corrosion takes its course and fills in the gaps. If I've got that right, then I should be good to go.

Alternatives are to shop around for piping that I can align or to use something like JB Weld.

Any comments or suggestions are appreciated.

Jb weld will smell for a long time, every time it gets hot.

You can weld the pipe. I considered solder, or silver solder.
