Good video, makes sense from a physics viewpoint. Heat the tubing to make it soft as well as expand it. I used Dishwashing liquid over the connector and heated tubing end in boiling water for 2 min. Began installation at 45 degree angle. It worked. You can even continue torque it into place minutes afterwards. Thanks for that.
@Boat Fittings perfect video i bought a 25mm hose for my 28mm bilge pump. Popped the pipe into hot water for 5 minutes until floppy ish straight away it went on. With a good tight fitting exactly what you need on a bilge pump. 28mm pipe is expensive and will definitely be to loose.
After searching for an hour realized there were no fittings that would fit it so got a hose of almost the same size. This did the trick it took me a couple of tries but it is on there very snug. I wish I had seen this video before I opened the tape which was my last resort. Thank you for sharing!
Can also use a heat gun. Recently went to a bigger pump with a 1.125" hose outlet. Attwood T-1200. Was a Rule 500 there so the hose is 3/4". I found a black rubber hose end which had been stretched over an old Sherwood G7 pump. That fits the Attwood outlet and the 3/4" rubber heater hose fits into the black rubber hose tightly. No clamp needed on the hose slid into hose arrangement but could add one.
Hi thanks for your comment. In the video the internal diameter of the hose was 25mm to fit on a pump with a 29mm outlet. The hose that was used in the video could be found in the following link : www.boatfittings.co.uk/p/clear_braid_reinforced_pvc_hose_tube_for_water_and_air_delivery Kind regards, Richard
This very issue caused me the biggest headache 😢, why on earth don’t bilge pump manufacture’s just make the outlets to suit standard hose barbs and hoses, I wasted so much time and money trying to get a good solution when all I needed was this video, lol, I didn’t think nylon hose would stretch with hot water so didn’t bother trying it 😩😩 thanks for the info 👍🏼
Absolutely do not do this on a boat. Get a correct size hose instead. What are you planning to do the day the hose splits down the end and leaks and you’re in the middle of the ocean? You can’t just cut the end off and put it back on and retighten, if you need something to heat it with and the engine isn’t able to run without the broken hose and the rain is pouring down. When on a boat, prepare for the worst. Do so in other parts of life too.
Someone is probably going to comment: "it’s just a bilge pump" There are other hoses in a boat too. Someone is probably also going to comment: "but the next size up is too big" Then it is not the correct size. Always bring a caliper.
And, one more thing: don’t use Jubilee brand hose clamps. For some reason I don’t understand, they have mismatched the band length to the curvature of the worm holder, so all of them create a D shape when tightened. It’s literally just my Jubilee, UK branded hose clamps that do this. None of the worm style hose clamps I buy from china do this. Just don’t use the ones that have a thin band with holes punched in it, those are weak. Use the ones that look like Jubilee clips but aren’t branded Jubilee.
