Help wanted with gas fittings on boat

[rogerthebodger]

As we get all kinds of machinery from all over the world some of out pipe fitting suppliers stock all funny fittings.

I normally take in the fittings I need to match up and my friend who runs a pipe fitting supplier will arange what I need.

If I know what you need I could try to get something for you.

Do you know what size the male male elbow as this could be replaces with one that will get you a swivel pipe fitting to use 6mm i/d hose.

On low pressure fuel and gas I have used that type of fitting and clamp the hose on with a twin ear crimp and found they are better than a worm drive clip

I guess the the answer is not to buy a boat built in the southern hemisphere if you want standard fittings.

There are some strange things in the southern hemisphere!

IMHO increasing the bore by one size will be a good move. I have 6mm bore tube and with a four burner hob + oven it is insufficient should I wish to have everything alight. Also, If you can change to copper tube, run inside a plastic tube, you will be future proofed. As far as I know there is no time limit imposed on copper. If you can find room for a bubble tester that would give you peace of mind too. Even though it is not a requirement. I presume that because you have a cat’ the cooker is not pivoted. If it were, an armoured flexible hose would be required between it and the fixed pipe.
Incidentally, in my experience it is the insurance companies that call the tune on marine gas installation standards. Mine demands a current gas certificate before I can legitimately use the cooker/oven and that means an annual check, as the certificates relating to mobile installations are only valid for 12 months. Best check the small print.

It would be easier if it were copper pipe rather than rubber and the cooker is not gimballed so that would not be an issue. The problem is that the boat is in Croatia so doing the long routing and fitting with metal pipe would not be easy. Once I've made this switch to DIY fittings it will be easy to pull out the old pipe pull through the new one every 10 years or so.

My insurance company appear to have no interest in the gas fittings but it's obviously in my interests to keep us all safe.

It is sometimes possible to feed a 15mm plastic pipe, plumbing, such as water or cistern overflow, then shove 8mm copper through. Simple compression fittings then, with a bayonet type cooker connector or adaptor copper to hose.

For gas use compression fittings with copper olives, I read on here last week.

Best not to use garden hose and fittings.

A chap I know used them and he blew the end out of his Nissen hut and finished up in hospital for a week.?
