Not pliers, but they work well. You insert the point between the hose and the fitting and work your way around the fitting, breaking it loose. Doesn't hurt the hose if you're careful.

Yea got a set of them and sometimes they work and sometimes you poke holes in the hoses. i got that same pick as is in your picture but theres is a couple of places that i can not get to with a larger pick.

I recently used a new one of those hose tools, and it did have a very sharp point. I only have one myself that I got used and the point is fairly dull. Not sure if its from tons of use, or came that way. But it would take some effort to poke through a hose with it. Maybe try sanding the tip down some if they are too sharp?

Otherwise, flat jawed channel locks might work well for you.

I have never tried it but would a smaller-sized reinforced rubber strap wrench provide enough grip to spin a hose on a flare fitting without slipping and just spinning around the hose? Not the regular cheap type with an all rubber strap, but the ones with the rubber coating impregnated into a thin high strength woven strap so it will not snap in two on you while cranking on it.

Temporarily wrap some water pump pliers with electrical tape to get the hoses off... then take the tape off when you are done.

Take a piece of old radiator hose, cut off like 2", slit it down the center, slip it over the hose you want to pull and use whatever you want. I'm assuming that being these are warranty the have fairly low miles and haven't had a million miles of heat cycles and corrosion to weld them on.

I've got three or four sizes of those, LOTS of sizes and types of picks, and use one of the Lisle hose remover pliers if I can get access and it works ok even on larger hoses by pushing the hose off the fitting.

^ Like they said - these work pretty when there's room... but I still use a razor blade to cut hoses off of heater core stub outs.

The description says it works on hose up to 1/2", would they work on 1" hoses like the OP has?

When you squeeze the grip it spreads the jaws. On smaller hoses it pushes them right off, on larger hoses you need to work it around the end, maybe use in combination with a pick, but once you break the seal all the way around any size hose should come right off pretty easily.

I feel your pain brother. I do the same thing as you, work on trucks. Except I mostly work on cat day in and day out. For me I simply use a hose pick like first pictured. If that doesn't work then I just try hand twisting it off. But next time I across a real ****** one I might try what other guys suggested with my 22 in. Knipex pliers.

But if it's a smaller one we keep hoses like that and ones all the way up to 2 in. Id in stock where I work and it won't come loose after 10 min I just cut it. No point in messing around with a freaking hose that's glued onto a fitting. And then when it goes back together I usually put just a dab of grease around the fitting to ease install and since it is highly likely that I will be the one taking it off again, it will be easy to remove it next time.

The guys at work use aviation cannon plug pliers to remove hoses without destroying them. A google search will find them for you. My mobile phone-fu is not that handy this morning.

I think I want some of those Facoms, too.

Well the tool you should be using is your hand. If that's not working trying biting you lip a different way and maybe it will work better next time

Is that what these pliers are made for or are they for something else originally? I saw a pair on eBay last night and didn't have a clue what they were for.

They are made for these electrical connector. The white part in the jaws is likely a rubber gripper.

I think Canon was the original manufacturer, but they are also called "military" or "mil spec" connectors. They are common on aircraft. Some can be quite large diameter. Usually ridiculously expensive. (I think the housing is machined aluminum.) You used be be able to buy NOS ones from military suppliers pretty cheap. The outer ring screws down to hold the 2 halves together.

With proper gaskets, the bulkhead half can be used to make a truly waterproof housing.
