Rink and others,

There are different ways to connect a gas hose onto a copper pipe. It sounds like Rink has a compression fitting rather than a hose crimped directlty onto copper pipe. It also sounds like he has a compression fitting with an olive (compession ring) rather than a flare...re his original question about how to remove the compression ring. If possible try to do a repair that is compliant with regulations otherwise consider it temporary. Also it is obviously important to be very safe with gas.
I agree that a good nose is no substitue for regulations but neither unfortunately can they be ignored. For example, I had to replace the gas installation on my Maramu to get a gas certificate. Without a certificate a boat can't be registered or sold here. The copper gas pipe had to be changed to one which was plastic coated. The compression joints are flared, which I guess is more standard these days than olives, though regulations vary from country to country.

Well said Mike and Chris I echo your last sentence.

Yvonne has a good nose and good ears too, vital to pick up problems before they become disasters. Not much point in calling for a tradesman to fix his work from 1000 miles out at sea.

Hi Rink, and All
A cautionary Tale
Â Â Please exercise great care with the modern "pressure bonded" cooker to copper pipe connections.
Â Â Before setting out on our planned circumnavigation we replaced the old cooker in our Santorin. The new TaylorsÂ came with precrimped pipes from the cooker to the copper pipe end with its connection. We took off the old cooker pipe, threw away the old hose, took off the connection(and for some unknown reason - BBQ?) kept it.Â
Â Â SomeÂ 5 months later, after an Atlantic crossing and 2/3 through a Pacific crossing, my wife smelt gas whilst cooking breakfast. All off and investigate.
Â The official "corgi" rubber/steel braided standard pipe had slid free from its supposedly pressure crimped connection and gas was pouring into the boat.
Â All hatches wide open and divert the downwash from the balooner through the cabin floorboards up etc etc..
Â Later, I inspected the failed connector, because it is hydraulically crimped the tang that the pipe fits on is smooth not like the old ones which had serrated rings.It is perfect for domestic use but several days of gimblaling, which we only did whilst cooking, had worked the pipe off the tang. (And yes I did have the loop that was supposed to prevent that)
Â Off with the official pipe end and back on with the old one - cut off the (useless) crimps push the pipe onto the serrated rings, cut back the braid so that the clips compress the pipe, and 3 small jubilee clips. No worries since then - 13 years ago. And yes - we do inspect regularly.
Â Please remember, Gas qualified technicians (Corgi) deal almost exclusively with fixed installations - even if they are leisure qualified - that means mostly caravans and BBQ's.
Â Â This was the most dangerous incidentin over 40,000 sea miles and 15 years on the boat.
Â Â I trust jubilee clips that I can check and tighten and a visible rubber section that I can inspect - I do not trust some anonymous automatic machine. (Now a bit of a rant) Health and Safety Regulations have made people expect machines to look after them - Sailing teaches you to look after yourself - thank God.
Mike & Chris, (her with the sensitive nose!!)

Thanks for your reply. I'll check the info. I am also looking for some hands on experience to share. I put some photo's of the bimini in the Razor's Edge photo folder. Just in case you want to use it.

It may help to check out www.socal.co.uk they have all parts for Eno cookers. Click on toolbox where you will find a wide variety of hoses and fittings for gas bottles.
I hope this is of some help to you.
On a separate subject, you did a great job with the canopy/bimini on Razors Edge, we are currently trying to do something similar at the moment.
On retrospect is there anything that you would now change?

I want to replace my rubber gas pipes from the bottles to the copper pipe and from the ENO stove to the copper pipe. As there are compression fittings being used I assume there will be an old compression ring left on the copper pipe. Has anyone experience with replacing the rubber gas pipes and removing the compression rings?
I have to do it myself since there are no certified companies in the marina where I am (Turkey).
