xort Lots of lubricating for fitting on hoses. I was concerned it would keep the fitting lubed and perhaps slip out under pressure, hose clamp or not. Guess that was a bad assumption.

Quickstep192 Unless a hose is crazy expensive, if I'm going to go to the trobule to remove it, I'm going to replace it with a new one.

I've discovered the hard way that you have to be careful if you slit the hose with a utility knife. I've had a couple of times where I put a nick in the fitting and it leaked after the new hose was installed.

As for tips for removal, I've had success taking a small screwdriver and shoving it in between the hose and the fitting and then rolling it around the hose. It stretches it a bit and breaks the bond. Be careful not to let the screwdriver blade poke through the hose.

As for installing, there's a lubricant that's made for those rubber hubless fitting for cast iron pipe that works for water hose. KY works too. For fuel lines, I use a little 2 stroke oil for lubricant.

fullkeel7 Bought a small strap wrench that works wonders with auto hoses, but the hoses have to be dry and oil free. Works on all sizes I've had to remove, although I have not tried the 1 inch and below variety. Always used the twisty turn manhandle method with the small stuff. So if you have some room for the strap wrench, it works well and with out damage to the hose.

Think I bought mine at Harbor Freight... but may have hit the erase button on that one.

beej67 Astroglide > KY for all boat applications, mechanical or recreational.

timebandit Crisco, Pam, butter, bacon fat, olive oil all should be ok for all hoses.

Motor oil, grease, silicone spray, suntan oil, vaseline, KY jelly and snott should be good for most any hose also.

chucklesR Ive found that blood from skinned knuckles is good as a lubricant, but not as good as blood from a finger slashed trying to cut a hose.

I'm sure that didn't help much, so I'll leave you with a good tip: use a hair dryer instead of a heat gun -

beej67 I always use a bit of spray silicone lubricant when putting hoses back on, if it's not potable water. Is there a problem with that?

capngregg There is a tool made specifically for breaking hoses loose from fittings once they have "cold-set" in place. It was first named for the automobile industry repair trade so the name implies that it is just for radiator hoses. The tool is called a "radiator hose removal tool". (AKA: Booger Hook)

There is a post in one of the threads on this site that shows a picture of the tool. I think it was shown in a "how to" step by step replacement of shaft seal packings. (stuffing box flax seals)

The tool comes in many sizes and has a few special bends in it's shaft with a pointy tip at the end- be careful.

Just about every auto parts store has them as does Walmart and all the hardware stores. The tool is very inexpensive and a handy addition to your on-board tool kit.

jrd22 I've found a heat gun to be my best friend when it comes to removing and installing hoses. Keep it moving so you don't over heat one spot. Try to get a small flat screwdriver inside to break it loose if "glued" on. Hot water works too but very time consuming.

merlin2375 A good pair of vice grips and a towel for those hoses that you want to re-use will go a long way. Put the towel on the hose then clamp down with the vice grips. A little bit of twisting to get it loose then pull it off.
