19mm hose onto Blake’s seacock

[StefanSG]

I have tried till I’m blue in the face, using boiling water on the hose, cutting slits in the hose, but it doesn’t want to go on. The 3/4” Blake’s seacock seems to have a Barb that is more like 22mm OD. Anything to try before I start going at it with a hand file ?

Boiling water is not a very useful means of softening the hose. A hot air gun is by far the best tool for the job. Heat inside and out.

I use a cheap hair drier. Much better than hot water. Heat both the hose and the metal fittings.

Sadly Im currently afloat without access to 240v, and my Inverter has packed up !

well just an idea im sure youve tried. Once you have heated the thing up with hot water, insert something inside the pipe like a wooden bung or handle from a screwdriver/chisel, wiggle the thing about then try. can be effective but im sure you may well have done that. the best thing though is to give up and have a brew, going back to something after a break always works!!

Try a more flexible hose. I've just replaced a toilet inlet hose (19mm) with one I thought was a bit soft and skinny for the job. It went on easily, doesn't leak, and seems to do the job.

I agree with all of the above
I just replaced some of the hoses on my old Princess. All the hoses are 3/4’’, and the thru hulls seems to be 1’’. I changed to a softer hose, used a wooden conical plug a hammer a bit of soap and some heat. I was not easy but after a couple tries it worked. I did not use to much heat, and waited for the hose to cool down before installing.

I have heated hoses successfully using a blowlamp. Care is needed of course but it can be done.

Lubrication always helps in this kind of situations.

I'd get it on while it's stlll warm.

I had some trouble applying enough force if the hose was warm, however it was a hassle either way. For the next truhulls I might make my life easy and buy a reducer from Trudesign.

With cautious use of a blowtorch (only slightly singed the hose) and some soapy water as lube, the hose went on first go, so I did the 1-1/2" and that was easy. Thanks for all the recommendations (I used most of them !) I'll put a battery powered heat gun on the christmas list.
