Hi,

I did this once before but can't find who I used as a supplier.

Can anyone point me in the right direction for cheap hose barbs to fit a solenoid to allow 8mm orange gas hose to be connected directly to my evapartor solenoid.
It seems like a good idea as this orange hose is far nicer looking and much cheaper than the ugly black faro stuff. Also its a lot more flexible so should it drag along the ground, it will take longer to fail. As its fairly soft, I can sqeeze it to get the pressure up when my tank is running low (I'm easily strong enough to compress a liquid).

OK - so I'm actually using the solenoid to control vapour output from a 28mb calor regulator screwed directly into the bottle.
The solenoid will be fitted into the low pressure orange hose after the regulator.
Real questions;
I'm looking for the most economic way of doing this - sourcing the barbs and solenoid. I'm assuming a solenoid with 1/4 npt fittings?
12v - current is not a big problem in this case, ~1amp is fine.
Its going in an external gas bottle container with a safety vent and drain.
I like the valtek solenoids as I already have some spare coils for those.

All suggestions that do not involve accomodating parts in my fundamental orifice are much appreciated.

:lol: I thought it a bit out of character for you to start a Toolless type thread!

But after you got serious I didn't understand what you were trying to do.. can you explain a bit differently mate?

I read it as electronically control the output of a gas bottle regulator with a valve in the orange hose you'd have to goto a cooker/heater or similar?

Some brilliant wording in the OP though!

You should really have registered a different username then we really would have thought Toolless had come back from the dead (he can't still be alive surely?).

It seems pretty clear to me. You've got a Calor bottle feeding something but you want to be able to turn the gas supply off. You want to be able to do it electrically rather than by getting to the gas bottle and twiddling the knob so need fittings that will allow you to connect gas hose to a Valtek gas solenoid. I'd suggest eBay as you seem to be able to find just about anything on there, but someone else may know of a supplier. Autogas2000 do a lot of caravan type gas stuff as well as conversion equipment, you could try giving them a bell.

Yeah, for better effect :lol:. Although with the recent problems people face registering on this forum he might have had a long wait... That's a discussion for the relevant thread but i wish admin would get it sorted.

I did think he wanted to do that (what you and Bri realised) but wasn't sure enough to want to start a reply without confirming first.

Tinleytech / Autogas2000 / GasIt (formerly FES Autogas) will sell you the necessary bits. A few ways to go about it - first choice would be whether to put the solenoid in the vapour flow after the camping regulator or between the gas bottle and regulator.

The same principals could be used to make a handy anti fart device, could be a simple affair or more complicated such as a low power radio transmitter carried by spouse, receiver connected to solenoid, solenoid opens whenever receiver doesn't pick up transmitter signal. Transmitter gain could be adjusted to suit the 'environment' (Gilbert is a radio specialist so could probably help with this). But now we're into the unappreciated realm of parts in fundamental orifices.

Hi all,

Brian - yes it’s to control the vapour stage post regulator.

It’s to isolate the supply from the bottle automatically after a period of time (will be run from a 60 minute timer).

Simon – I’d thought before the regulator would not be possible as the reg screws on to the bottle BUT now you’ve mentioned it – I did used to have a tilly camping cooker that screwed directly on to the bottle (I think it ran at bottle pressure – OK as long as the bottle didn’t fall over I suppose). If I could find a hose with fittings to go between the bottle and the regulator – that would be preferable as less restriction.

Whilst I can source 6mm units cheaply – an 8mm one will set me back over £40 from the (truly) great guys at Tinley Tech (~30 for the solenoid and barbs plus delivery plus vat).

The rse valve (Simons radio controlled flatulence controller) sounds ideal and a lot like some of the ‘man overboard’ systems that alarm when out of range. Simon – how does yours work? Is it a total block or is it more like an EGR diverting the gas back to your nostrils?

Thanks GIilbertd, I’ll give autogas2000 a go.

I was half expecting to find the barbs cheap at RS or CPC but not so far.

Initially, I wanted to go 8mm as that’s the diameter of the orange hose but there is a much thinner (<6mm) copper vapour hose later in the system. So if I can’t find an 8mm one with the bits I need (under £25 delivered) then it’s going to be a 6mm one and see how it goes.

Thanks all.

It is possible to mount the camping regulator remotely from the camping bottle, in fact some motorhomes etc have such a setup as standard, again any of the mentioned suppliers should be able to supply the bits.

Many options for getting from 6mm to 8mm, a simple copper pipe joiner with bit of unequal size pipe sticking out either end and orange hose pushed / jubilee clipped on would work / braze 8mm end to 6mm fittings, I bet some firms could sell you a 6mm to 8mm adaptor.

A flame out device which shuts off power to the solenoid would be a great safety feature.

I didn't go into the wider scope of the flatulence device but would consider diversion of gas to nostrils an odd on / trainer / deterrent. Other possibles would be filters to separate those gummy stinky flaky heavy ends from the vapour etc. The ultimate upgrade might be a compressor and storage tank to use as vehicle fuel with a CNG conversion.

My tendency to squeak when I walk and my ability to peel oranges in my pocket are leading me away from the high spec stuff (yes, I know – what’s the point in saving money if you’re not alive to spend it).

It’s either going to be an 8mm solenoid with copper hose sticking out and the orange hose jubileed over that or a 6mm with 8mm hose barbs. I have got a copper flaring tool somewhere that used to do brake/fuel hoses – that might put an end on it that could stop the jubilee slipping off.

I see what you mean about the training aspect of the diversion valve. In the event of non-compliance it could be activated. Perhaps collecting the gas to be used in conjunction with a veg oil diesel conversion could be interesting? In the event of an official observing that ‘chip shop’ smell – you could add your own. I suppose the heavy ends could be a problem with the lambda sensor?

Anyway – no cheap options found although ‘Discount Marine’ do a switch and solenoid for under £150 ffs.

You know Marine is code for the same thing at 4 times the non-Marine price already though?

Too true! Anything to do with recreation that might remotely be considered a niche associated with rich people. I've got an old boat, alas not rich, but prices for bits are eye watering. Had a customer the other day who's into aircraft... bet some firms have had his trousers down :lol:

Oh yes - just spent £250 on a plastic 'water lock' and 6meters of 50mm exhaust hose. But is is lloyds approved!

Local chandlers - m6 100mm stainless (A2) bolt = £3
Local nut and bolt supllier - same item 35p

But the man who sold me the bolt for 35p didn't tell me how clever or good looking I was and didn't ask me to tell him 'tall tails of the sea'.

Simon - bet the boat I use (not even mine) is tattier and smaller than yours! Do you still have that huge 2t out board?

Dunno about huge mate. 70bhp, but yes I still have it. Had no time to work on it due to LPG work and have even just about forgotten where I was with it... but it wasn't looking positive last time I messed with it. I really don't like 2 strokes, the un-smooth running and stink didn't bother me at all when as a kid my dad had boats with 2T engines but these days I want an engine to be smooth and not stink... I may just pull the powerhead off of it and try to graft on a 4 stroke engine instead, run it on LPG with a mixer. Problem is that to do that with a modern 4 stroke, unless I fitted the ECU and some other bits from a car I'd be looking at a Megajolt setup and probably more hassle and expense. :lol:

Result! I have the solenoid and barbs at a good price.

I emailed Charlie at Tinley Tech having resigned myself to paying £40 for the hardware

Charlie had an alternative option - an item listed on the tt website as petrol solenoid that comes with 8mm barbs.

I have it here and its actually marked "Petrol - LPG - CNG"

Fitting this weekend.


LPCG – I remembered it as bigger than 70 and two of them! Must be getting old.
These days I’d argue that 2t gave great power to weight but I bet that’s not the case with yours :)
Smells can be a problem in a boat – diesel has been the cause of seasickness for me. But an old fashioned 2t oil (arghhh for the smell of Castrol R) could be forgiven if its not smoking too heavily.
I thought the sound when ‘in the power’ is one of nicest engine noises – right up there with a rotary. Although rough idling and bogging down are disconcerting (and detonating sounds are sphincter loosening).
Go for it – dust it off, reach for the mirror shades and get it screaming across the water like it’s the 70’s again! Its what the RNLI donations were meant for.
