7Kg Calor gas bottle.

[CalicoJack]

I have been using 4.5Kg Propane Calor gas bottles, but I have now discovered that I can fit 7Kg bottles in my gas locker. Assuming that I go down this route the fittings on the 7Kg appears to be different to the 4.5K am I right in this thinking and is there anything else that I will need?

How to safely connect and disconnect gas bottles

Do you mean butane?

Propane bottles have a female POL connection

The old 4.5 kg butane bottles had a 21.8 mm left hand male connection but larger sizes have a 21mm push on connection.
Do you have a cylinder mounted or a bulkhead mounted regulator?

I thought all propane bottles had the same connection regardless of size or supplier

They do, but this discussion appears to be about Butane cylinders which in the OP were incorrectly referred to as propane. (the small calor Propane is 3.9Kg, if the cylinder is 4.5Kg is is butane.

Which, of course, has also been discontinued

This is to convert from 7kg butane to a left handed thread standard 4.5 kg butane.. blue bottle.

Yes, the OP is trying to convert from 4.5Kg butane to 7Kg butane which is still available and he has found fits into his gas locker. and he wants advice on changing the fittings to make that work.

He has consfuded a lot of people by wrongly referring to them as propane.

At any rate, a new adapter and perhaps a new means of securing the larger bottle should see his problems resolved.https://bigwhitebox.co.uk/product/gas-bottle-floor-holder-bracket/?gclid=EAIaIQobChMIyZv-yq2qgQMVF4btCh2gyAnGEAQYByABEgJ-G_D_BwE

Opps, sorry. It’s butane for both sizes.

Your old left hand threaded screw on regulator wont go on the 7 kg bottle.

Best way is to buy the correct push on regulator for the new 7kg bottle and connect the gas hose directly on to it.

We are doing the same thing, 2 advantages are you dont need a spanner to attatch the push on regulator also the on /off valve is a lever that moves through 90 degrees to let the gas flow which is less likely to be left fully open by accident.

It depends on whether he has a bottle or bulkhead mounted regulator. I asked in #3 but it is being kept secret.
If bottle mounted then a new clip on regulator, or the adapter suggested by wingcommander, is required. Preferably the clip on regulator.
If bulkhead mounted then the adapter is the solution.

Thanks for the link, I couldn't find the adaptor when I was searching.

Have finally just swapped an empty 4.5k butane for a full 7k butane via a local Calor gas agent. Charged £31.50 lnc Vat..
Fitted a new bottle mounted regulator.
With a bit of a struggle it just fitted in my gas locker
