Flexible Gas Hose

oldbobsbus · Guru

Where are the hoses Bill?????

Before or after the regulator..

If they are before the regulator you need to buy special flexible pigtails only available from Gas Centers that service the industry and have them fitted by a licensed LP Gasfitter.

If they are after the gas regulator you also need to buy LPG certified hoses and if they are in your van or MH or a household installation you again should have them fitted by a licensed LP Gasfitter.

If they are on your BBQ and running on less than 10kg cylinders and the hose is on the low pressure side if the regulator you can legally do the job yourself as that installation isn't covered by the code..AS5601-2004..

All gas installations have to pass a leak test and then you know they are safe.. smile

This information is offered as a guide only..

Hi Everyone,
Firstly one of the gas hose (armoured flexible line) failed on my camper the first night of a trip a few years ago. Looked like it had been crushed somehow. Blamed the cooks son as he was the last to use it.
Great cooking for two weeks on one of those single burner gas stoves. Replaced it with another. No more trouble.

Replaced camper with a caravan. No trouble for a while but at the start of a long spell living in it one hose failed again. Went to the local Jayco dealer for a replacement to be told to use copper pipe instead. Seems that the gas degrades the rubber in the flexible line
Have done so but don't like them. Have to bend too much each time I change cylinders.
Has anyone heard of this as I would like to switch back to flexible lines. At home we have 2 BBQ's & a gas heater all connected with flexible lines (not armoured) that give no trouble but don't want to be caught out again. Won't be as bad as I carry the old flexible lines as spares.

Hi Bill, I have had a gas hose do the same thing just blow may be from age ,I went to a gas dealer and he told me if you bye a good quality flexible hose should be ok ,the copper pig tail one is the best,he told me the cheap flex hose can start breaking up from inside and stuff your regulator as well ,so go for a good quality flex hose or the little piggies tail.

You would think Teflon lined hoses would be better ? Guess they would have to be custom made ?

We had a leaky Bromic one which we replaced with another Bromic from a gas supply shop - Bromic say to replace them with a copper pigtail supplied by Bromic on the recall site:

I didn't think teflon and LPG got along to well? Or maybe it was something else

Braided LP Gas hoses have a yellow tracer woven into them and rubber hoses have LP Gas printed along the side of them..
Nothing else is approved for use with LP Gas..

PTFE is Teflon.. It is approved on LPG.. Id like to know what they use if Teflon isn't??
It cant be burnt easy either..

Don't know if this will help, but we've had flexible S/S gas hoses on our bus for a number of years without problems. Personally I prefer flexible ones, we once had a MH which had solid copper gas piping fitted by a qualified gas fitter and were always tightening connections and getting breaks fixed, because we do a lot of our travelling on dirt roads. So fitted flexible s/s ones on this bus when I converted it and placed them in poly pipe sealed with silastic, even put them through bends and have never had any trouble with them. When I took it to the engineers, they said it was a great thing to do, as it protected the gas lines, secured them and allowed them to be flexible without being damaged.

I've used Teflon in race cars using E85 and alcohol .

My gas man says its over the top, but I know it's good stuff .

. It's really flexible, doesn't change like other flexible hoses.

Looks Good Kiwi - the label on my Bromic hose says "Inspect regularly, replace periodically" which means they ain't designed to last long.

That recall was in March 2001...

It was for a Black Rubber flexible pig tail hose designed to be used between the cylinder and the regulator and would normally be exposed to the weather..

If anyone still has a hose that old in use I suggest it is well overtime for its replacement..

I do believe that the braided hoses with the yellow tracer do have a teflon liner..
