Lubricant for silicone exhaust hose?
I was planning to use some of the blue high temp silicone exhaust hose to connect my headers to my tips. I was doing some test fitting of the hose to one of my tips - only pushed it on about an inch, and had to absolutely wrestle with it to get it apart again. I want to be able to get these apart easily for servicing down the road and don't want to have to resort to using a box cutter on my expensive hose. Are these supposed to be installed dry, or can something be used as a lubricant to allow them to come back off easier? I realize that you definitely don't want them coming apart or leaking when installed, but I figure the clamps and the fact that they are securely squeezed between the tip and header will ensure that they will not come apart or leak.
Never had much of a problem getting the rubber couplings apart, but these seem really tight and "sticky". Thanks.

Budman - I used the blue silicone for exhaust on two engines, a ZZ502 and then the 557. I had engines in and out of the boat and changed exhaust systems a couple of times before ending up with KE's. To be honest I found the black rubber more difficult to deal with than the silicone. I used Dawn dish soap to help slip the blue on. I made an "L" shaped tool out of some scrap steel I had kicking around and would use that to help loosen and pry the hose loose when needed. In the end I think the blue is more forgiving and overall easier to work with.

bud,a lubricant is used to aid im assembly and after a little time it is gone.it will not aid in removal.

Silicone spray seems to dry out and get sticky to me. If you want aerosol can I'd go with white lithium grease. Honestly if it was me if use whatever I had laying around instead of making a special trip.

Vasoline, water ski boot lube or slide glide (stuff electricians use to fish wire bundles through conduit). Vasoline will remain the longest for future disassembling, with the other two water soluble they will "go away" in short order.

On some apps like water circ pump hoses we use Super Lube Grease for easy removal upon boat wiinterizations - it is clear as you can see right thru it.
It has a temp range - 45 F to 450 F. It will not run nor drip or dry out or melt. it does not form any deposits or gets hard or has additive fall out or separates. About 15 years ago, I put this stuff in a plastic bag and left it in the shop of temps thru out the years all over the place. As of today, It still looks and feels the same as if I bought yesterday. No additive fall out or any drips or any melting in which is hard to believe in itself over that many years..
its also listed as a USDA food grade lube rated H1 for food contact.

It's surprising that the silicone hose has such higher temp ratings than the rubber stuff. It's about half as thick. Guess it's all about the material it's made from. I have a tough angle I'm trying to work with, which is the main reason I'm using the silicone.
