I bought a replacement gas hose for my cooker and did not get round to fiting it. It is still in the bag and I am about to get round to fitting a new one. The one I have is dated 2011. Is there a shelf life for gas hose ?

I don't think you will get an answer. The problem is that if there is a fire you may have trouble with the insurance - naturally excepting all questions of personal risk.

My local Calor supplier says the standard orange rubber hoses should be replaced every three years. The one fitted to my boat was at least 15 years old, and good as new.

Not worth the risk / bother of fitting a hose almost at the end of its recommended life of 5yrs IMHO although, like OH, I've had it in use for (very) much longer.
I while back tried to use a length ( unused ) that had been on the garage shelf for a few years beyond its recommended life and as i pushed it onto the nozzle it split lengthwise!. Funny I thought, that went on easily!

I use the HP braided, so splitting is less of an issue

Service Life
BS3212 or BSEN1763 hoses should bear the year and name of manufacturer.
We have no specific recommendation for the exchange interval for vapour hoses, but it is considered
that the normal useful service life of such hoses is 5 years.

I find the HP hose rather more difficult to push onto the standard Fulham nozzles. I need to be able to pull it off and push back on again when changing bottles because i have a Gaz bottle with bottle mounted regulator.
I've noticed that the nozzles for HP hose are different to those for LP hose. I don't know if that is significant
I have HP hose at the moment. Its (over) due to be changed so will probably go back to black Lp hose. Unfortunately the local camping shop only stocks the HP stuff.

Bend the hose over . Any cracking indicating perishing and the hose should be replaced.
But if replacing a hose it would make sense to buy a new hose with this years date on it. The hose is £1.99 a metre at our local caravan shop and you should only need 1 metre.

The one I referred to in #4 showed no signs of cracking when bent so that's not an infallible test!
If you buy from a caravan / camping shop check the date on it before you buy. When I looked at what our local camping supplies shop had it was already two years old!

I had the gas done the first year I had the boat. The orange piping was dated 1982 and looked as good as the new stuff that was fitted.

I'm cynical about this 'change-by-date' thing as well as I've never had a leak, even with cracked stuff that was ancient and being replaced anyway.
However, I am worried to hear of a failure of unused pipe : I have been led to believe it is the chemical makeup of the gas that attacks the pipe over time, so a new bit still in the packet would be expected to be OK regardless of what is stamped on it.
I do accept that it could be difficult to explain the use of long shelf-life stock in the event of an accident though.

If the hose cracks and causes an explosion, the evidence of its age will be long gone.

The gas alarm should sound long before an explosive concentration of gas is reached. 10% LEL ?

If I were attaching and detaching hose like that I would fit a quick release connector in the hose... http://www.towsure.com/quick-releas...RJCnL79bJ_DxGOEhzt8DDIRDdYJV8BemJ4aAs4p8P8HAQ

Yes I was wondering about one of those. I suppose they must make a good reliable leak free connection.
Although if I fit a marine regulator

The recomendation is that the hose be replaced after five years from the date gas first passed through it. VicS, can't you lift the gas cylinder out of the locker whilst it is still attached to the regulator and hose?

Don't have to ask this question here. Hoses have 'must be replaced by 20**' stamped on them.

Thanks for the insights. It seems a service life of 5 years is recommended and seems sensible

That may become more common. My local shop is the same and they tell me that they will no longer buy in the LP stuff.
