Light weight gas bottles
Permalink  

I am looking at possibly changing my two 9kg gas bottles with the 7.5 composite gas bottles

https://compgas.com.au/products/fysp-7-5

 

what experiences are out there on these, its a large cost but is it worth it, and yes I would like to reduce weight on the drawbar now that I have a bike rack and two bikes

 

also how hard is it on the road to get then re-filled ?

I would have bought them a long time ago, but they don't fit the space I have.
New build will not have gas.
Filling should be no different from any other approved and in-date bottle.
They are available in Europe as swap bottles.
Cheers,
Peter

Or the other option is to move from 9kg bottles to 4.5kg, cheaper option and still lose weight ?

Our gas seems to last quite a while

Neighbour with experience of composite bottles filled at up to 400 BAR suggests the re-certification period is 15 years.   He also warns that quality of gas used to refill is important as the metal fittings used may corrode if less than pure LPG is used.    Apparantly the refill process is the same as for the steel BBQ type bottles.    The profileration of Swap-and-Go type outlets may cause an issue finding an outlet to fill the bottles.    My local BCF is the only outlet for a long way that can and will fill gas bottles.   Cost wise, very expensive way to save about half the weight of a standard steel bottle.

No. 10 years like all the others.

The "metal" is brass. Same as all the others.

Cost wise, very expensive way to save about half the weight of a standard steel bottle.

And get a bottle that will never rust (inside or out) and shows the exact gas level accurately at all times.

Cheers,

Peter
