I am confident I’m my ability to assemble and leak test gas fitting.
This SHOULD NOT be attempted IF YOU ARE NOT ENTIRELY CONFIDENT IN YOUR ABILITY.
I purchased a set of fitting and hose for transfer filling from a donor Calor Butane 15kg to camping Gaz 907 bottle. see photo below ( component parts need to be assembled and can be bought from gas spares suppliers on line. (Choose quality brass parts only) sets can be bought online comprising all the parts you will need ( suggest a NRV is included for added safety)
I assembled the components and joined them to the hose using correct size spanner’s (ensure a Non return valve fitted to the assembly)
I filled two partially empty camping Gaz cylinders from a larger 15kg blue Butane bottle. Large 15kg Calor gas butane ( current cost £52 / 15kg)
the 907 cylinder is stamped with the Max capacity for both Butane & Propane volumes.
local Hardware shop refill (exchange) camping Gaz 907 bottle £37 each
using the 15kg butane as the doner at a cost of £52 equates to £3.46 per kilo x 2.7 kilo capacity of the 907 = £9.36 per 907 fill vs £37 from an exchange from a dealer.
a saving of £27.64 per fill. (The cost of the parts pay for themself with the first fill).
