When replacing heater hoses

[Ghoste]

Does anyone ever put any sort of lube at the ends to make it easier getting them on and off?  Or is everyone just putting them on there dry?  And if you are lubing them, what are you using, some sort of silicone, petroleum jelly, plain old black chassis grease?  I have to change mine and the old ones were baked on there pretty hard and that is what got me to wondering about this.

cut the olds ones off ... &  i have always just spray a little WD40 on the new ones
if they are still tight for some reason, can warm the ends up a bit with a hot air gun , then spray wd40 ..

Thanks tan top, the old ones are off already but I thought I'd throw the question out before replacing them.  Didn't want to just grease them up with something only to cause other problems for myself down the road.

no don't grease it won't clamp properly ..just spray WD40 for lube

We use a little bit of a product called Sil-Glide.....I think that's how it's spelled...anyway...it's like a vaseline type of lube for brake sliders on calipers....just a thin film and the hoses go on very easy

I've used a very thin layer of silicone grease and never had a leak.  You can get it as spark plug boot release which used to be available from GE Silicones or in a tube from Dow Corning as DC-4 grease.  I got the latter at a industrial supply house.  Regular stores never have it.  But I use it for lots of stuff.  Never goes bad and is not miscible in water.

Silicone grease won't damage rubber like petroluem based greases. However, I've never used it for that purpose. So years down the road when the hose is ready to be changed again, it's anybody's guess whether it'll come off easier or not.

I ended up using the WD40 for now.  Would dielectric grease be silicone?

[GreenMachine]

Silicone grease is dielectric grease. I'm not sure if all dielectric grease is silicone.
