LPG/oil in hose

[Phil and Lol]

Am going to change my rubber 'pig tail' feeding my LPG regulator, I have read about issues with rubber hose created by oil. Has anyone installed a stainless steel hose and did it help resolve the oil issue?

YES

Ours happened at 1 year old. So replaced with SS lead, been Ok since 9 years.

Thanks for that.

The situation is well summarised here

The thinking behind changing to stainless-steel gas pigtails was that the LPG itself was ‘clean’ and that regulators were being damaged by the phthalates used in the manufacture of flexible ‘rubber’ gas-hoses.

 

You’ll see from the link that this theory has been largely discredited and (as was always the logical argument) received wisdom now is that the ‘oil’ is present in the LPG and that the more sophisticated regulators introduced in the early 2000s tolerated the oil less than the simple on-bottle regulators previously used.

 

I bought a Hobby motorhome in 2005 and had two Truma/GOK regulators fail in fairly quick succession. I then revised the gas system so that the pigtail led upwards from the gas-bottle and I also fitted a genuine Truma-marketed ‘rubber’ pigtail. I sold the Hobby in 2014 and the 3rd regulator I had fitted in 2007 was still OK.

 

If you really want to protect against regulator oil-contamination, you’d probably be better fitting a Truma gas filter (though these haven’t exactly been problem-free themselves!)
