Bilge Pump/Hose mismatch

[richardbrennan]

Having spent a fruitless afternoon trying to fit what I now know is a 1" hose onto a 1 1/8" bilge pump outlet, I wonder if anybody knows where one can get a converter for these hose sizes. Rule do one but only for 1 1/8" down to 3/4", neither do there appear to be any pumps currently available that have 1" outlets, which would be an alternative solution if a little costly. The other obvious answer would be to replace the whole hose but this would not be easy and I assume would give me the same problem at the other end with the hull outlet. I might add I have tried all the usual dodges with hot water and washing up liquid and the like, but 1/8" seems just to much to try and stretch the hose.

This may help, 25mm to 28mm but silicone so a bit more "stretchy" http://www.hyphose.com/index.php?main_page=product_info&products_id=349

What I've done in the past is warm the pipe up with a hot air gun and then open it up using a couple of levers inside the pipe.

If you know a friendly gynaecologist he'll have just the kit you need!

Yeah ,I have recently been amazed by all the Rule pumps with 1 1/8 inch hose connections and ASAP Supplies don't do hose to fit it though you can get skin fittings.

What I did was to buy the hose off ebay. 28mm bilge hose

Thanks for the suggestions; unfortunately I don't know a gynecologist, but I'll give it a go with a heat gun, (we just used hot water today), and then if that fails, try the converter from Hyphose.

If you put a 1" hose on a1 1/8" pump, you'll restrict the flow quite a lot. I'd update the lot including skin fitting.

1 1/8" is, by my reckoning, 28mm so:

If you can get a shott , say 6 ins, piece of 1/18 its possuble the orriginal 1 ins will fit snugly into it making a slieve joint.
If not its shoud be fairly simple to make a slieve from suitable plastic or simelar material. Access to a small lath would be handy.
Use a good quality adhesuve sealant on the joint

I have ordered the Vetus converter as suggested by alahol2; many thanks for all the advice.

I know I'm too late, but for the future, I drilled a hole in one of my wooden emergency plugs, cut it in four quarter sections. put a cone on a screw and made an expander for use with a paintstripper hot air gun. Job done.
